85 5.0 High/low idle issues May 13, 2019, 03:13:37 PM So i have a 85 5.0 and have been dealing with this issue where the car starts and warms perfectly except the fact i have the depress the gas pedal to get it to come off high idle, Except when its pretty warm outside, the car starts without kicking itself up on high idle at all and has trouble on first start without really giving it some gas but once it warms it idles just fine. I was thinking it has to do with the carb choke thermostat but im not sure and dont want to replace a bunch of stuff randomly even though i most likely will anyway. Now this is not a big issue just something more or less i would like to iron out. ALSO when car is idling i can rev the engine and not every time but usually while the car is waiting to warm up it will stick around 13-1500 rpm then i have to press gas again to get it to kick back down. could this be related? i have checked for voltage at the choke thermostat as well and i do have power.
