This has been going on for a while now. I`ve changed all the coils and just changed the plugs. What gives. The engine misses not only on cold starts but even if it sits for an hour or two. After in reaches operating temps it`s totally smooth. The back two plugs #7 and #8 are always rusty and I have no idea why. It`s not head gaskets. Anyone else have this problem?

 

Does it miss just when it's at idle? If so, you probably have a dirty(easy to remove and clean) or worn Idle Air Control valve.

same problems here with the rusty plugs.

There was a problem with the heater core connections leaking down on the number 7 plug on the 99 and 2000 models, but i always had some rust on my plugs on 7 and 8 and I never wash my motor down. Has to be coming from the outside and dripping on the back of the motor? I stopped icing my intake at the track and never had that issue again. I even used to wrap the ice in a towel.

Maybe that's it?

 

not sure, i have a scanner if you need to borrow it. also left you a message, not sure if you got it, call me up.

 

Okay, what I`ve done so far have been, coils, plugs, filters, IAC cleaning and even a new MAF. Now` I`m thinking fuel like the pump issues on the 00`s. It starts fine with high idle and then when it idle`s down it bogs and misses. Worse if you drive right away without a warm up. HELP

Tom I got your message, Thanks Bro I`m calling back now!!

 

have you done any mods lately?

 

02 Sensors ???
Tune ???

 

No new Mods Talli-Man. And Rob, I just put in new plugs and the coils were replaced with Accells a few Months back. I gotta do a fuel pump pressure test and see whats happening on start up. If not I gotta drop it off at Sals. I'd hate to dump it on him but as usual, better him than me.
