Running rich or burning oil or almost anything.

What color ?

When it's cold or hot ?

Is the car warmed up ?

Too many factors

FYI.......Start your own thread for more assistance.

Okay, the plugs are in. Wasn't that bad...I expected worse from what I read on these forums. Anyway, misfires are better, but not non-existant. It is MUCH harder to make it misfire. I have only been able to make it happen sitting still in the parking lot and VERY lightly comming off idle.

Otherwise she runs better than ever!. All plugs look equal whitish. That is a good sign of engine heath I take it.

I will check the maps soon.

Its always going to have some aversion to low rpms. Unless you get better headers. Even my Unequal length GT Spec headers killed my stumble down low, but it also still killed some rumble.

Okay, so I have reviewed the Tip in Enrichment A and B tables from my current map and my stock map. Both are identical, so that shouldn't be an issue.

The problem seemed to have smoothed out after the plugs, but it is still there. I noticed it seemed worse today. Just thinking about all factors....I wonder if it's temp related. It is VERY hot right now and it was the other week when I made this post.

I drive my car for business alot and sometimes find myself idling for extended periods. This is when I notice it most and the engine is heat soaked at those times.

Otherwise it runs better than ever. Maybe I should just not worry about it:/

Switch the coils around. See if you get the same mis-fires

Huh that's odd. Could be your IAT I suppose. Also the tip-in enrichment tables should be different to take into account the intake your running. Then again it's probably one of those odd issues where it didn't matter I guess.
