High idle stalling at turns - Third Generation F-Body Message Boards

92 Rally · 12-14-2009, 04:07 PM

so as the title says it is a 89 305 tbi and the car had been idleing low so re replaced the IAC and reset it to what the instructions said to drive at 40mph and it will reset and now it is idleing at 1500 in park and 1100 and drive and just today the car stalls when comming to a stop or turning after it stalls it starts right back up i am at a lost as to what to do now.

Problem solved by swapping ECM to another one runs like a champ now

still no success replaced gasket, checked timing injectors spray fine idk what to do.
would like to also note that when going to jump A and B on the ALDL service engine light never flashes is there something im missing or is it my computer messing up?

Re stalling at slow speeds, check your oxygen sensor.

Does the service engine light light when you have the car OFF but the key is in the RUN position?

If People Drove Any Slower They’d Be Going Backwards

When you see fog lights on in good weather beware. Low performance driver ahead.

How bout those nitwits too scared to drive without headlights in the daytime, and the nitwits that need headlights for a little rain

yes the service engine light comes on and stays on. i also have a ALDL cable for laptop but could never get it to work i have all the drivers and correct settings in winALDL. also how would i check and make sure my oxygen sensor is working correctly

To find out why you’re getting no code 12 with the A-B jump:

Make sure the key is OFF.

Disconnect the ECM.

Turn the key to RUN.

Let me know if the SES STILL LIGHTS with the key in RUN.

just a update still having high idle i have replaced TPS and no fix. i brought home a sanp on pro scanner and it will not read the computer either. when using the jumper the check engine light just stays steady and doesnt turn off. I just dont understand why it runs so smooth but is idleing at 1500rpm.

If you followed the procedure in post 5, and the SES was lit at the conclusion of the test there is a short to ground on the negative lead of the SES lamp.

That line comes off pin A5 of the ECM.

Check for a contaminated oxygen sensor.
