Question Asked: Engine Surging and Hesitation While Accelerating
February 15, 2010, 12:09 PM
My regal is surging while idleing and hesitates like it is losing power when I accelerate. It only does the hesitation sometimes and when the engine is hot. I had my ignition module, all 3 coil packs, spark plugs, crankshaft sensor replaced. Vacuum hose and fuel filter cleaned. I have been to 4 different places and none of them can figure out what it could be. Code 42 came up back in December which is the C3I Electronic Spark Timing Failure. My service engine light did not come on since I had it reset. I had all this done and it is still doing it. Someone told my cam sensor could be bad but that should of came up on the computer because the mechanic said he tested everything and they were fine. Im tired of getting the run around. So if you know what it could be. Please feel free to respond. Thanks
