Car Forum / Pontiac / Pontiac Fiero / September 200685 GT staling
I got an 85 GT 6cyl about a month ago 63K miles its been running good until the last week now it stalls at intersection when I stop. It runs fine while I am driving it. Last night I took it out and it ran great today agian it keeps stalling when I stop. Help Thanks Hank If it's an automatic transmission it could very well be your torque converter lockup solenoid is stuck on the locked position. Again if it's an auto disconnect the connector on the tranny and see if it corrects the problem. > I got an 85 GT 6cyl about a month ago 63K miles its been running good > until the last week now it stalls at intersection when I stop.

They often get dirty and become slow to respond which causes stalling and or high idle. It can be (carefully) removed and cleaned. > I got an 85 GT 6cyl about a month ago 63K miles its been running good > until the last week now it stalls at intersection when I stop.

So I took off the AIC from a parts car I got this spring and installed it and it now has been running great for 3 days also the exhaust has quited down as well, other people have noticed that too that the past few weeks the exhaust was louder than usual. More noticable when you down shift or just race the engine and let go of the gas pedal as the engine reduces in RPM.

I've had a few Fieros and it seems like I've had to perform this same repair on them several times each. It looks like the design is such that some dirt gets sucked into the valve. I probably should have mentioned that you can also put a small drop of light oil on the shaft that the pintle rides on. This seems to work a few times before you have to spend the bucks to buy a new valve. It also helps to clean the pintle seat up inside the throttle assembly. Only 63k on an 85, that's pretty sweet! Have fun with it!
