The check engine light came on after the car was ideling very rough. O'rielly Chevrolet said that the #5 injector was sticking, they flushed the system & replaced the fuel filter for $207.73. Two weeks later on 2-25-02 the check engine light came on again. I took to O'rielly chev. & they said it was the #5 & # 3 injector had to be replaced. The first time the #5 injector was sticking the service rep. Said it was because I was using cheap gas. I changed the type of gas to chevron & after taking another trip, I had the same symptoms & after taking the car to O'rielly chev. The #5 & #3 injectors had to be replaced. The total costs of repairs for both times is $717.88. I don't recall, other than the level of octane, reading in my owner's manuel anything about using a better type of gas, but Chevrolet agrees with the service manager at O'rielly's that this is the cause of the problems with the injectors in my car. I would appreciate any help that you can provide. I feel that I shouldn't have major repair problems with a vehicle when it has was only 1,181 miles out of warranty. I have a friend that owns a 2000 Malibu ls & she has also experienced problems with the #5 injector, but at least her car is still under warranty. Thank you in advance for your attention to this issue.
