Question about 1994 Cadillac Seville

1 Answer

I own a 94 Seville and when i start it up the idle fluctuates between 600-1250 rpms but when i put it in drive its find but then it will start acting up again and when your doing anywhere between 38-52 mph it kinda feels like its missing it strange and someone told me it could be a "idle speed control" but i don't really know and was wondering if anyone else knew of anything that might make it do that????

My car idles roughly and jerks. The rpms fluctuate and the lights flicker when it jerks and shakes. I just had someone change the spark plugs, could they not have done it right?


Yes, first it shouldnt take an hour to do spark plugs, also there may be an HT lead loose, but most likely incorrect plugs, wrong gap or worse, a cracked plug if they did them up too tight. I would remove them and check everything asap as it will be putting stress on your coil/coils.

The normal idle for your engine should be 550 to 600 RPMS so thats not to far off . But the fluctuation is more likely the crank pisition sensor then the EGR valve this engine has a condution called crankshaft wip witch is normal but going down a rough road can somethimes set off a misfire code It wouldn't be a bad idea to take the EGR valve off and clean it and check it but the CPK would give you the fluctuation in RPMS . It still could be a few outer things but this it the most likely cause

What was it doing before? was the idle fluctuating before you cleaned the iac. If so then you probably need to replace the sensor. what did you use to clean the sensor? Some IAC's are sensitive and cannot be cleaned without damaging them.
