Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello. Do you have any more history on the vehicle?
I does not really sound like a throttle position sensor to me.
When were the spark plugs replaced? Have you had any other issues?
Ok, let me know. I would like to see the fuel trims because they may help in a diagnosis.
I would replace the spark plugs as soon as possible and that may help.
That really sounds like you have a misfire issue.
