I own a 94 Camaro V6 3.4l and had/have issues with a misfiring engine. When it first occurred a mechanic installed new spark plugs and replaced the ignition wire set. After that the engine was running perfect no misfiring and definitely more power than before. So I was very happy, well until about 2 weeks later. While driving on the highway the engine went suddenly from perfect to misfiring really bad. Back to the shop. They found wires and plugs were still fine, but there was no output by cylinders #2
, 3, and 4. But #1
, 2, and 5 had good output. Compression was at 125 psi.
I had to decline the recommended replacement of all 6 fuel injectors since the cost estimate was about 2k, which is more than the car is worth. One mechanic mentioned that maybe bad fuel could have caused the 3 injectors to fail and recommended filling up with high octane fuel to "clean out" the injectors- is that a possibility/ good idea?
Thanks a bunch,
