CTK22, you have solve your jerking problem by engine swap, good for you. But has anyone ever solved the jerking problem without engine swap ? No really I mean fixed the jerking problem? Why so many VQs have these problem after certain years of usage? Is that a engine flaw or what. I've notice that even in the states they r having this similiar problem. I don't hear a camry or an accord having such problem (same manufacturing year). I'd reaaly like to find the culprit. Any suggestion?
