Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,Are you getting a check engine light and if so do you know the fault codes ?
If you are not getting any check engine light and there are no engine vacuum leaks then I thing there are a couple of things you should try, start first with removing the negative battery cable and then take some carb cleaner and a soft cloth and give the throttle body a good cleaning, while doing this also give the MAF sensor a good cleaning with some MAF cleaner. After doing both, reconnect the negative battery and start the engine and allow it to idle for 15 to 20 minutes to allow the computer to relearn the closed throttle values. Give this a try and see if will resolve the problem for you.
