With my windows rolled up I can hear the engine stumble and the rpm needle just bairly will drop and pick up again. Its almost invisible unless your really looking at it.

If I tap the gas just a bit it goes away and its not at every stop I Jake only 30% of the time it will idle in a lumpy way.

Anybody have a diagram of the vacuum lines And whats the best fuel injerctor cleaner to use? Thanks for all the replies you guys are solid awesome.
