1997 Cadillac Eldorado ETC - Engine Stuttering/Stalling
 

Hi all,


I recently bought this car (a couple months ago) with about around 160,000 km on the clock. I've had no problems with it up until lately since the engine has been stuttering at low RPM followed by dying completely. If I keep the RPM over about 1,200, the problem isn't really pronounced, but it does stutter once in a while. It always starts right up after stalling with no hesitation. Sometimes the problem doesn't happen at all (it tends to happen within the first half hour of driving, but it's getting worse).


I've been told it could be a vacuum leak. I also did some research and found it could be a dirty throttle body or potentially a bad connection or faulty crankshaft position sensor or camshaft position sensor. The latter two I've been led to believe after checking the codes.

Any insight would be much appreciated. Thanks.
