'97 Chevy malibu, 100,000 miles. I have had my car at the mechanic twice in the past two months because the car didn't feel right and the check engine light came on. They gave me a tune up and a Motorvac. The light is off but the car still doesn't feel right. It doesn't feel as powerful, I have some rough idling, and when I drive it just feels rough... It doesn't feel right, I don't know how else to describe it. I'm not great with cars and my mechanic hasn't fixed the prob, so I was wondering if anyone had any ideas. Thanks so much!

100k could be the tune up, fuel filter, MAF sensor

Have it scanned for codes. Check for vacuum leaks.

Suggested Repair

Scan for diagnostic codes, check for vacuum leaks, and inspect the fuel filter and MAF sensor as possible causes of the rough idle and reduced power.

Conversation Summary

The owner of a 1997 Chevy Malibu with about 100,000 miles reported reduced power, rough idling, and a rough driving feel after a tune-up and Motorvac service. The check engine light had come on earlier but was off afterward. Experts suggested the fuel filter or MAF sensor could be involved and recommended scanning for codes and checking for vacuum leaks.
