Light throttle Hesistation/Miss?!

1995Qsport · 04-25-2008, 06:45 PM

Ok i have a slight problem, while taking off going light throttle the car will hesistate and then pick up if you tap the gas a little more. When revving in neutral its a clearly audible miss-fire did the dark test and #6 wire was arcing on fuel line, fixed that and still does it.
Possibilities: Dirty MAF- Did have to remove to install new ISV when the problem worsened.
Plugs/Plug wires about 6k on plugs and unknown on wires. Maybe im missing some small thing that could cause this problem, Oh and no know vac. leaks : )

Let me hear your idea's!
thanks

A/F gauge reads Pig rich when it hesitates, maybe if it read lean i would worry about filter, it might be injector ill have to test em. Im gonna pick up some maf cleaner today after work ill let you know the outcome.

you need to replace the rubber seal between the plastic intake plenum and the intake manifold. Mine was doing the same thing only to find that i had a vaccum leak around there
