Question about 1985 Pontiac Fiero

1 Answer

Engine Dies When driving or idling, the RPM guage will drop to zero and within a second or two the engine will die. It will restart immediately by reengaging clutch ( if driving) or by using the starter if sitiing and idling. It will run a minute or two and the process repeats itself. It has ran perfect since a rebuild this spring and a new distributor was installed then. I suspect the control module, since, I believe, it also controls the fuel pump operation if ignition is lost. I tested the module on a module tester and it shows good. I'm wondering ,being an intermittent problem, it may still be bad. The current module came eith the new distributor. I'll start by replacing the module if you think it would be first on the list. Thank you.

Check the crank trigger sensor as well this can be presenting the way you described i dont feel it is the throttle position sensor but you may want to test that as well if the crank sensor comes back clean

1996 mercedes c280 dies when put in drive


Engine stalls or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Hi! The MAF (mass air flow) sensor is surely faulty. The MAF has big contribution on the engine performance specially on the idling an vacuum supply. If the MAF is faulty the rpm will drop eratically or die. Regarding the overheating problem, you may want to check the radiator blower for it may be tripping that sometimes it works and sometimes won't. This can be a good cause. Hope this helps and thank you for using FixYa!

RPM drops to zero at idling after engine accelerates when warm


This may been an ignition module or a MAF sensor, this car may need to be diagnosed using a OBD I computer code reader to accurately diagnose the problem.

Check your vacuum lines, make sure there is no leaks, and go from there, then all you electrical connection in the engine compartment.
I have a 1996 Jetta Trek Edition, the hoses, and wire harness, are so brittle, any movement can cause hoses and wire insulation to crack.

Cold Start Idle Issue


Problem might be the air control valve, it's located at the right side rear of intake manifold and has a hose going to the air intake duct from the air cleaner, as a test you might try pinching off that hose when the idle is a problem.

1999 300M 150,000 Miles

Car dies when coming off acceleration or at idle in traffic or at a stop. I can watch the Tach go to 0 RPM, some times it will restart immediately other times it is hard to start, so far I have always been able to re-start it and Drive on. Does anybody have verified fix for this issue, I have seen posts saying can and crank sensor, throttle body, EGR, and many more ideas... Do not really want to just start replacing parts with the hope that I eventually get a fix. Help...
