If throttle is quickly pushed to the floor from idle, RPMs climb very slowly - sometimes misfires. Better response after RPMs are up but still not right... Car runs sluggish. I've checked for correct timing and vacuum leaks. Recently replaced: cap, rotor, timing belt, O2 sensor, plug wires, plugs, fuel inj. seals.

Any ideas?

open the hood when its dark out... rev the engine and check the plus wires for arcing... you may have gotten a bad wire

you could probabley change your fuel filter, and check under your intake boot where it connects to throttle body there could be a hole, also try twisting your distributer cap a little bit each way because it could help with a timing issue.

i am sorry twisting the cap wont change the timing but can give you a better fire if your cap has been twisted to a bad position previously.

I `ve rotated the distributor body on my
`91 passat 16v and it worked
Anyway check ignition timing , spark plugs
and fuel filter
I hope it`s not low compression
Good luck
