S-Trim w/Powerpipe Users

What does you fuel system consist of (intank pump (put a new "sock" on the pump? might be clogged if still stock pump), external pump, # injectors, using fmu (what disk)? Change your fuel filter lately? What kind of plugs and are they gapped correctly? Cap and rotor for distributer changed recently? Spark plug wires?

I would check/replace all of these than if it doesn't clear up, head to a tuner and get that car on a dyno so you can see if your running lean, fat, etc. Yes, it's worth the money.
