Engine Performance problem
1999 Pontiac Grand Am 6 cyl Automatic 143000 miles
I hope you can give me some answers. My car has been idling rough for a while & has been getting poor gas mileage. We thought it was the EGR valve, replace that & the problem still exists. Two days ago after getting fuel, the car started jerking and bucking when I would accelerate. If I decrease pressure on the gas pedal, it stops. The service engine soon light has been on for a while. We took it to AZ and the it came back with a code for multiple misfires. My plugs & wires are new, they tested the Ignition Module & it is fine. Could these problems be caused by clogged Fuel injectors and it just needs to be cleaned? I do buy really cheap gas!
