Engine Performance problem
2002 Lexus IS 300 6 cyl Two Wheel Drive Automatic 92694 miles
I have changed my spark plugs twice in the last 2 months and everytimne I do, the car runs great for a few weeks and then slowly begins to hesitate more and more. During my last plug change I replaced the center ignition coil because the dealer said it was missfiring on the 3rd cylendar. But still it hesitates. I don't really trust the dealer to go in and " look" to see what's wrong for $400.00 and then fix whatever they find for about $900.00. But I haven't been able to find anyone who has ever heard of this sort of thing before. I hope you can stear me in the right direction.
