mad idle problems on 85 gsl-se
hey there. ive got a 1985 gsl-se with 158,000kms on it.
just recently i have been having some really weird idle problems.
whenever i start the car it will rev up the usual amount, then as it slows down to what should be the normal idle speed it will drop much too low (about 500 rpms or so) then if you give it a bit of gas it will shoot up to about 1500 or 2000rpms and rev like that until the car heats up. THEN after that when the engine is running at operating temp. the rpm will flucuate horribly. it will start at 750 or so rpms, and then drop to 500, then surge back up to 750 after a short time. i have been racking my brain, and the brains of everyone else i know but i CANNOT figure this out. i have been thinking fuel pump problems. but i cant be sure.
can anyone out there help me!?!? if you need more specifics or anything just ask and i can tell you. THANKS

i dont know if this is a symptom of the problem either, but ive been getting shitty as hell gas mileage aswell. so far ive driven 230kms and im at about a third of a tank. and during acceleration in first gear at about 3500rpm there is a little surge of energy it sorta feels like. i have a feeling it could be my fuel pump starting to go or something. anyone agree?
