JDM D15B Studdering at 4000rpm????Help?????
Thought it was the timing and tried to move the dist. around a bit, but no luck. When the vtec kicks in it starts sputtering almost two wher it sounds like constant backfiring??? It started after I replaced the old dist because of a bad bearing.

The motor runs perfectly at idle, but as soon as you rev it around 3800, it starts sputtering.
