I just put a new motor in my dc2 and when I start it the idle sits at 2,000rpm after it warms up the idle will eventually drop to 800.If u let it sit for a while it will start idling up and down from about 800 to 1k rpm.I have already rlaced the IAC valve,TPS,MAP sensor,redone the FITV and replaced all vacum lines.Anyone know any other ways to fix the problem???

have you tried messing with the idle screw yet

 

Yes,Im not sure where the stock setting is but right now its almost all the way closed.

 

im running a 70mm bbk...i had idling issues...i found out that the gasket they gave me overlapped where the actual throttle turned..it was restricting its position to go back to idling state...so i trimmed that..so check ur gasket if its overlapping...

also like said...play with ur screw..mine tends to flucuate once in a while but goes back down after a few secs or so...but hell..ill live with it...

 

Sill cant get it to idle right.

 

Have you done a valve adjustment?

 

Havent had a valve job done yet.Also when I let the car idle it will run for like 10 sec then it seems like it stumbles and does it repeatedly.

 

Do the valve adjustment, see what happens. That might fix you right up

 

Will get one done soon any other thoughts on the subject?

 

Check that distributer out.

 

Dizzy has a new cap,rotor,and coil.The bearing still spins like new.

 

try bleeding the coolant, might be air trapped in the line

 

will try the coolant tomorrow

 

I know this is an old thread...but was it one of the temp sensors?
