Hello, this is my first post here. I have been searching and couldn't find anything that helped so i have to ask. Just bought a 1992 Toyota pickup ext. cab 3.0 v6 auto 4x4. Runs good, idles good, but after its warmed up and you come to a stop the engine stalls. Doesnt matter if your in drive or neutral. The only way i can stop it from dieing is either slow down very slowly before comeing to a stop or throw it in neutral and brake with my left foot and give it gas with my right. I should also say that its not dieing after you stop, it will die if your turning into a driveway halfway into turning. I pulled the tps,which i think i tested right, good. Also tested the air flow meter, also good. Someone has removed the egr and crimped the hoses, so i think it might be a vacuum hose not hooked up right. The throttle opener does not have a vacuum hose going to it and it runs at a lower idle with it hooked up, and dies just the same. Any thoughts?

 

not sure about the vacuum hose not being connected there, but have you tried cleaning the throttle body and butterfly? this takes care of a lot of low idle and stalling issues at work for me. just a thought.

 

Yea i will give that a shot. Thanks. I forgot to mention too that it does not have a CEL. either the bulb is gone or has a short in it as it does not come on when you turn the key.

 

Clean and test the DASH-Pot. Also search for "Idle speeed control valve" or "ISCV", and read up on them.

 

Thanks Co, will give that a shot.
