Check engine lite came on at 98K. Replaced all 6 spark plugs by a shop.
Mechanic says that #6 injector is 'lazy'. Does not inject proper amount of fuel during idle but ok at higher rpm(1,500). Since I do alot of highway driving, I just let it go. Now at 120K, I'm noticing #6 getting
more misfire when accelerating. Had shop replace #6 injector. But now the mechanic says their diagnostic equipment says #5, and #6 is having misfire only at idle speed, but when revved up, misfire goes away. He swapped coils on #1, and #2 to #5, and #6 with same results. Mechanic says could be a blown head gasket. My thoughts is, if it is a compression problem, then why the misfire goes away at when engine is revved about 1500rpm. I just want a second opinion on this. Thanks for your help?
have the same problem?
