2000 Saturn sc1 1.9L SOHC MT
to refresh: I replaced in order
coolant temp sensor
I also cleaned the throttle body & gasket
Yes thank you your info got me thinking.
. Its a leak like you say.
So I did so more reserch I have found several cases w/ the same symptoms turns out there problem was a leaky intake gasket.
Then I went out started my car and sprayed carb cleaner at the #1 cylinder intake and a change to the idle occured, so I'm pretty certain thats the issue.
I havent had time to get to this or the EGR valve. I am planing on changing the EGR valve & gasket first and then the intake gasket after that.
I will let you know
