Sorry about not being more explicit. My car is a 2002 Millenia S 2.3 engine. This what I have done to narrow down my problem.
Switched coils from other cylinder and changed spark plugs reading shows #4 miss-fire. So now I am thinking Injector. So my question about procedure to replace this injector.
Any suggestions?
One other thing that adds to the confusion, after running the car in the afternoon and having a missfife, and then in the morning runs fine on all 6 for a while, and then the miss fire comes back.
just doesn't figure. But the test shows #4. So what do I do? And how do I go about it?
Thanks for your addvice in advance.
