Suspension/Steering / Re: Problems with Cobra brake swap
The one that was on the car felt find but bled off when you held the pedal down. If you stepped on it again it would do the same thing.
All three of them I couldn't get a stiff pedal out of and the fourth one worked perfectly with almost no bleeding.

Electrical Tech / Re: PMGR Starter Issue
Pretty much every starter has the same tooth count reguardless of flywheel tooth count.
When I did my sn-95 t-5 swap, I found out that there are two different offsets for the nose of a starter, 3/8" and 3/4" length. The first starter I tried. It hit the flywheel but could not pull back enough. After doing some reading. Lot of guys had the same problem and added a 1/2" stack of washers. That when I found out about the nose length difference and I got the correct starter out of a pick up truck.
My thinking. It might be possible that you have the wrong lenth and the teeth don't always make contact.

This is me pulling codes on an 87. I am using a volt meter to show how you can do it without the check engine light.

Engine Tech / Re: Strong engine stumble
The entire time I've owned this car, its gotten bad gas mileage (between 20-25 freeway) and its had an intermittent stumble that I just couldn't find.
I have occasionally gotten an o2 code and even swapped out the side that had the issue twice. Both times I assumed that it was fixed because it seemed like the issue went away.
Even after I did my head gasket, it seemed to run better, but I was bummed that it still had a miss. I did a basic tune up on it and couldnt find anything wrong so I jist left it as is.
I've owned this car for about 3 1/2 years. In that time I've put around 120k on it. I though I knew it pretty well and had it pretty well figured out. In all that time, ive only been able to chirp the tires on wet pavement.
Not only does the stumble seem to be gone, but the intermittent issues as well. I haven't quite ran a full tank out of it yet, going to do that over the holiday weekend.
But it also seems to have all kinds of power down low. Up top feels about the same, but I can now spin a tire from a dead stop and keep it spinning.
I honestly believe that wire was messed up the whole time ive owned the car. It also had a brand new o2 sensor on that side when I bought it.
Its not perfect, feels like it might be pinging a bit at low rpms/high load, and feels like it needs a real tune up. Maybe its time to change the oil and air filters for the first time.

I hate to say it, but there are really only maybe 6 wires the car needs powered up to run and there are really only a few critical sensors. The computer will tell you if things aren't working.
If you don't want to check if the computer is working, I really don't see much point in trying to fix the car.
It takes two minutes and a paper clip. Most 86's done have a check engine light, so we have to use a test light or a 12v buzzer or an analog volt meter.

Hopefully its good enough to drive to work tomorrow.
Seems to be running better. I'm hoping somehow this had to do with my strong stumble.
Pretty sure the wires were shorted out between the heated o2 wire and who know what that did to the eec.

Engine Tech / Re: Strong engine stumble
Soent about 30 minutes pulled the connectors off the o2's. One connector is melted at the o2, so i need to either replace the o2 or repin it with another and haven't gotten the other side fished out quite yet.
Started it up jist for fun. Idles a bit off but seems to have fixed the fire and hopefully my intermittent stumble and battery issues.

Engine Tech / Re: Strong engine stumble
Is there no fuse or fuseable link for o2 sensors on an 86?

Engine Tech / Re: Strong engine stumble
Shut off the jump box and pulled the cable. I was able to blow out the visible flames. But I am at a complete loss. I've never had a car catch on fire, and the only wiring I could see In the area was the o2 sensor harness. Fuseable links don't appear to be melted. I am not going to have a chance to mess with it until next weekend. Gotta be in bed by 8 and up by 4:30 in the morning for work

I'm down to wiring or fiddly things. Working 6 days a week, 10 hrs a day 3 hours from home is catching up to me.

Engine Tech / Re: Strong engine stumble
I pulled the spare out of my engine (been sitting since probably 2007 and dropped it in. Car feels a bit lazy, might have gotten the timing a bit off, but it hasn't stumbled once since.

Engine Tech / Re: Strong engine stumble
After that the car seemed to run much better so I left it alone. Of course it started the random sputtering again. This time I put the fuel pressure on the window. Couldn't get it to dip or do anything funny.
Ran codes again, smog pump (82) which is bypassed. And get came back (34) so I am gonna mess with that next weekend. Ran another engine cylider ballance test and it passed, no more o2 code.
Since its still been stumbling, I pulled the dizzy/tfi out of another car. Cap looked pretty good and so did the rotor button. Cars running pretty good, gonna try to drive it again tomorrow but I couldn't get it to do anything bad.
I'm not convinced its the tfi/or pip, but it should rule that out if I have any more problems.
