Hi all, hoping someone can help diagnose. My new stroker is running well one day, won't accelerate the next. Has about 100 miles on it so far. New GMPP ZZ383, DEMON 650 VE, new GM HEI.
Starts fine, idles fine, vacuum about 20" off manifold at idle, revs high about 1250 (now), shuts down fine, will run about 7mph without throttle, but soon as I step on it, it misses, and will stall if I don't get off it..
Was running strong a day before, a little pinging under acceleration, was gonna address that when this happened.
No inline fuel filter, if plugged somewhere wouldn't idle be affected?
