What plugs/wires?
What did you gap the plugs to?
Have you done a boost leak test recently?
Is your throttle cable adjusted properly using the bracket bolted to the intake manifold?

That would be my guess.
Have someone press the pedal down all the way while you check under the hood to see if its 100%.

Boost leak.

Backfire, Slow/hesitant acceleration.

btw... what is boost...

how do i do boost leak test......


thanks again

Please search. There are plenty of write-ups on boost leak tests. Might want to check the VFAQ, DSM FAQ, or Tech Articles.

Heh. I'm pretty sure he didn't have his profile out on the initial replies.. So we just assumed turbo.

Lol. check your throttle cable. how are your plugs/wires?

That would make sense. I don't remember seeing a profile filled in, but thought I was going crazy or something.

Usually when there is a backfire, you're running rich. Add in the fact that you're experiencing a slow acceleration problem and you may have an issue with your O2 sensor or fuel system. Have you recently replaced or worked on anything fuel related, including the fuel filler cap, pump, FPR or injectors?

Slow acceleration is more a symptom of poor spark timing, but if you're running rich enough to be backfiring, then there's obviously at least a small fuel related issue.
