Body/Appearance/Interior / Re: SN95 seats DON'T just "bolt to our tracks"?
Oh, I'd prefer to keep the passenger side lumbar, and adjustable bolsters on both. No worries there - the stock frames would be ideal for me too, so if I can find new owners for the Mustang seats, I'd be happy.

Years ago I figured the later seats may be stronger too, but I've seen some threads mentioning that the SN95 seatbacks can also twist/bend and get the lean.

I have listed the seats for sale, and have a potential sale already getting lined up. Mostly a waste of money and time, but I'll at least recoup my costs and gain some experience. Just lost some garage floor space and storage of foam/upholstery for a couple years...

I'd love to do this Mustang foam/upholstery swap onto the stick frames, after repairing/strengthening my driver side seat back. I'd also likely refinish the frames, as you had.

The Wideband(s) are on a DataQ. I have the EGR blocked off right now, but also have never used it for o2 input. Hardwired via analog lines in DataQ only.

I just need to look at the spec sheet and reset the wideband map to factory range, check again, and adjust as needed to get close to the switching from the narrowbands (a bit above and below lambda of 1).

Yeah, I want to throw fuel at it again. When I did this weeks ago, it didn't clear anything up, but I was also on the dying coil. Need to re-do some tests.

Install second LC-2 wideband in passenger bank and hook up to DataQ, setup in BE, run engine until CL and make any adjustment if necessary to get wideband map closer, disable CL and mess with either injector values or MAF depending on which settings look like they'll be the correct correction, richen mixture a point and see if anything smooths out. Mess with timing and see if anything smooths out. Run car without alternator to see how it is on a fixed DC Voltage from the battery. Run second EEC-IV ground from battery to EEC.

These are some of the things that I'd like to perform and (re)test tomorrow. Simple tests out of the way.

The stock tune reading the stock MAF should be pretty dead-on though, with the factory tune. Stock airbox. Airflow metering should be accurate between it or the PMAS/Pro-M MAF.

Yeah, they're stock-like. TRW-L2305F30 pistons.

Block was 0-decked and TW170 heads were milled .030 to get 54c chambers. With those and the HO cam, there was loads of clearance when I checked. The clay looked to have almost as much as 1/2 inch - I didn't measure exactly as it was simply thick.

I am happy with the HO cam, if I could get the shortblock to run smoother at idle. Don't care about getting every last bit of power from the motor (even +30hp), it already moves fine with the parts it has. But if I were building a new shortblock today and knew I wouldn't have ptv clearance (clay), of course I'd try a different/newer style cam that's a bit more aggressive. I'd also run a completely different longblock, and wouldn't be cheap. Then I'd probably still have idle issues and hate driving the car.

Engine Tech / Re: Troubleshooting persistent misfire
Agreed on the pita, but carb is easy if you already have the intake pulled. Just re-use the old gaskets with rtv for the test, and new gaskets when reinstalling the efi intake. Degreeing the cam, I'd just advance it while in there already. I'd completely swap the cam if I wasn't worried about ptv - don't want to pull the heads. The motor has a ton of ptv clearance right now though - lots of clay thickness when I tested it during the head install.

Can you send me the set of photos from your other thread, so I can piece together what all you did? I can pm you my e-mail address if you don't have them up anywhere, such as dropbox, google drive, etc.

It sounds straightforward, but seeing is telling.

Engine Tech / Re: Troubleshooting persistent misfire
Still going to get you that datalog of my spark at idle this weekend. But until then I have more questions, what AFR are you shooting for at idle? are you hitting it? and when was the last time you calibrated your wideband sensor?

Whats your fuel pressure at idle and what does it change to when you pull the vacuum line off the regulator?


So you have an A9P running on a 4r70w. Which controller are you using to control the trans?

Sorry for all the questions there's just such a wide range of things that can affect idle quality and trying to give you any sort of good idea without being there is difficult.

The AFRs are simply switching around lambda, I run 92 octane "up to e10/whatever they have in the pump" sometimes, sometimes 92 octane e0. I have mostly the 92-octane from a chevron a few blocks away in there right now. Of course it's hitting lambda if the narrowband o2s are switching.

I haven't touched the wideband in years, but I do have a second new gauge-less one to install here soon in the passenger side. I've had an old aem thing in there that requires the gauge, and outputs the signal line from the gauge. Driver side has the Innovate LC-2 screwed ion.

FP was mentioned earlier - it's 33psi with 16in of vacuum, 39psi with vacuum detached. I'm going to play with some random tune settings this weekend to see if ANYTHING gets the idle any smoother.

4t70w is running from the original Baumannator TCS. Don't remember if this trans went in with the motor in the mid 2000's, or if I briefly ran the aod. I've had the 4r in there since before the Quarterhorse though, and likely before I ran a TwEECer.

Car has been in the family since 1991. It ran perfectly smooth with the stock powertrain, up until I swapped it out with the completely new motor. Has never idled correctly since.

Body/Appearance/Interior / Re: Seat upgrade ... attempt #2 ...
This post is incredible, how do we get the pics back and updated.  Would be a shame to lose all that info and work.

I second this - would like to see how this all fits on the stock frames. I'd be willing to throw the images into a folder on my web host, so these aren't stored on the forum itself.

I believe that this is the foam and upholstery set to use? https://www.cjponyparts.com/tmi-upholstery-03-04-cobra-style-sport-high-back-seats-1987-1989/p/U81-V/

For verification, are our Sport/TC seat frames and foam identical to the "1987-89 Mustang Sport Seats"? I've seen that mentioned elsewhere once on this forum.

I did some seat "upgrades" using TMI items as well.  I was able to take a stock set of Turbo Coupe seats and modify them.  First, I stripped them down to the bare frames, added upgraded "Cobra" style foam with more aggressive bolstering from TMI.  Then, I recovered them with a seat cover set from TMI that I was able to custom spec the color combo/material for ... the SVO Mustang used the same charcoal color, so it matched up nicely.  This allowed me to keep the adjustable side bolsters and knee bolster along with the lumbar.

Here's the link, but all of the photos have since disappeared:

Pics of the finished product ... you'll have to forgive the lighting.  This is where I ended, but there was a lot of experimentation along the way.  I did some hole drilling in a spare power seat track with some Corbeau seats, but just never got them to fit to my liking.  Looks like yours bolted up without too much issue,  Good job.

Do those Fox mustang "cobra" version sets work on our frames? Are the frames that similar, or are they identical to Mustangs?

Engine Tech / Re: Troubleshooting persistent misfire
You have a stock cam in it right? Personally never had an issue but I also know all cams are different from one another. Is it possible yours is different enough to cause an issue, maybe but seems unlikely. Youre right though putting a degree wheel on it is the only way to know for sure but seems like a long shot to me. I personally would start with different plugs cap and rotor the maintenance stuff that has to be done eventually anyway. Cant say I've ever had a set of plugs last me more than a year even when I was N/A, now days I go through a set of ngk 5673-7 in about 3 months at most.  I would also try and set base idle by unplugging the battery and clearing KAM unplugging the IAC reconnect battery starting it and adjusting the throttle plate until it idles where I want then shut it off and plug the IAC back in start it and let it run for a while sometimes Ive had to do it a few times after replacing my throttle body to get idle back to normal. You said it acts up at 2000 rpm right? Like its misfiring?

The cam that came out of a factory '89 Mustang longblock, yes. Originally had that with the topend from a '93 Cobra, and this A9P. I've been through various engine builds since then, with at least 3 plug wire sets, maybe 4 or 5 sets of plugs across the heads, 5 injector sets (three different 19lb sets, a 24lb, and a 30lb), 3 full distributors, 2 MAF sensors, 3 IAC valves, 3-4 EGR valves, 3-4 alternators, 3 batteries, a few new replacement engine and coolant temperature sensors, and who knows what else.

Kinda wish I just had an aluminum DART 351 block instead, machined from scratch and internally balanced...a fresh build.

I'll have to get a new parked video recording when I have some daylight.

On another note, my switching 5v regulator is arriving soon and I'll finally get the cluster's mechanical regulator replaced. Those three gauges have also annoyed me forever.

Engine Tech / Re: Troubleshooting persistent misfire
Someone today suggested that if I'm pulling the intake off to degree the cam, I should temporarily convert to carb to see if the issue persists. Seems like a reasonable plan, if the parts can be found cheaply enough.

Anyone know of the cheapest options to try such a thing? Would need the intake and carb obviously, and could just use a pump to pump from a gas can. igniton box. Sounds like I should have access to everything to test this, except the 4 barrel intake.

Really curious if the idle would smooth out by ditching all of the electronics, and this could potentially be a huge diagnostic test.

Yeah, they sell fox-mustang "Cobra-like" replacement foam and upholstery. I am still tempted to try such a thing out, but I'd also need to repair my broken or bent driver seat-back. There's things that I just like about the stock seats.

Would be easy to flip the Mustang seats.
