Re: Cold stall problem 700 1987

Hi Bruce,

Under the throttle body is a black screw like thing....this is what is most likely causing your problems...i had a similar one, except mines a manual, so it would make it to the end of the street then stall.....Given that the throttle body is clean and all, go to the left hand side (exhaust side) of the inner fender. There will be 2 connectors there, one is white with a red stripe, the other is white with a green stripe. What you have to do is ground the RED stripe wire....(Just use some alligator clips or something), oh, don't ground the green one, it comes directly out of the ECU for fuel mixture checking....god knows what would happen if that was done!! Now, with the red stripe wire grounded and the car WARMED UP (!) the idle should be VERY low, i.e. if you put it into gear the car will probably stall. Now, get a meter of some form to measure RPM (or just make an approximation using the dash guage) and adjust the idle RPM to approx. 700-725 (for manual, not sure about auto, sorry) but even that should get the car running MUCH nicer. Have you ever noticed that the car idles low when pulling up to a stop quickly? Should have noticed something like that...Once you disconnect the grounded red wire the engine will race to about 1200-1500rpm for a little while, then slow down....this is the IAC setting itself right. After this you should notice a HUGE improvement over cold idle.....My idle was about 200-300 RPM when i grounded my cable...the car was BARELY turning over.....(emphasis BARELY)...

That should be all you need to do!
