Engine Performance problem
2003 Saturn Ion 4 cyl Front Wheel Drive Automatic 140000 miles
Ok So I have a mind boggler, I pray you can help! My saturn just recently started having problems. Its lagging. I can push the gas to the floor and get no power, then it will randomly kick in. It has the worst problems when at cruising speeds. I took it to a mechanic who said that It was my transmission he was positive. Took it to a transmission specialist, they told me that it was fine, good as new, that my problem was with my engine performance. I then took it to a different mechanic and he called me before working on it and said that he wasnt sure it was the cause of the problem but my spark plugs were shot and my fuel filter needed replacing. I had him do that. He then called and told me that the car was running better, but the problem was still present. My fuel pump was tested and is fine. He said that the car is stuck in " open loop". He said my sensors were good and my computer wasnt getting a bad reading, my engine temp is also within the expected range. He could not give me an explanation on why this is. Im looking for some insight. PLEASE HELP!
