Took rusty 2.0 on a bit of a longer ride today, once i got into town i noticed a slight missfire/stumble after changing gears or coasting.

Seems to not do it as bad the harder i get into the throttle after shifting/coasting.

No smoke or anything and its not even thae bad, it clears up within a 1-5 seconds and its not really horrible at all but id like to figure it out.

Im *leaning" toward the map sensor, but the new plugs i had put in before the big issues started, the #1 was pretty black when i pulled it to time it.

Any yall got any ideas?

I cant keep track of all the stuff you've done so forgive me, but did you ever do the injectors? One could be leaking just enough to run good but come off throttle it leaks and floods the cylinder?

With all the fuel stuff done I'd consider the map or tps. But seafoam is never a bad idea. Hot soak it and you'll at least clear your yard of mosquitoes if nothing else.

Haha! I'm half afraid to try that here in southern California! Might have the whole city evacuating, thinking the wild fires are at it again! Haha!

Lol. I just do it at night. Usually works out well. Sometimes it doesn't.

Shit doesn't do as well as a parts washer or walnut shell blasting. But. It works.
