Please Help! I have a 2001 PT Limited Edition that I purchased 2 yrs ago, my car has 118,000 miles. I just recently had a tune-up done with Firestone because my PT started idling and running rough, I would even lose power while driving. I couldn't drive over 40 mph or the car would start to shake and misfire. Firestone changed my spark plugs and did a chemical flush to the car. its now been 5 days and my car start idling and running rough again. Do you have any advise on what is cause my PT to do this.
Thanks!
