One problem related to fuel injector has been reported for the 1999 Chevrolet Malibu. The most recently reported issues are listed below.
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.
