Idle issues (Page 1/1)
gb.84.fier0 APR 10, 07:45 PM
1984 auto with 88k miles. Replaced map, iac, ecm, o2.
Stalls at idle after you start it up after you get gas or something like that. There is gas all over the TB so maybe a leaky injector?
Also runs rich and gave a code 45. Also when it's hot out maybe 75 degrees it wants to stall at idle sometimes.

Any help would be appreciated!

It's possible you are dealing with a failing TCC solenoid. Learn more about it here............

I always feel the "4th gear" when accelerating, but once im up to speed with the foot steady at about 60, sometimes the car "downshifts" and rpms jump about 400. Could that also be a symptom of a failing tcc?

I'm guessing here... but that sounds more like possibly a vacuum modulator issue... if the factory 3-spd automatic has one. [EDIT] Turns out it doesn't.

Another guess... TV Cable adjustment.

I'll adjust that if I find out where it is.

Is this the connecter for the tcc? If I unplug it and drive the car a while and it doesn't stall then it's bad right?

I unplugged that connector and it is for the tcc. Drove it for a little bit and no stall yet. Ill keep driving but I am thinking that´s what is wrong. Thanks!
