my racecar will not rev past 6400 while running in third gear on track, as rpms climb it leans out and rpms stop rising. will rev up fine in neutral and up to 7 in 2nd gear
its a first gen integra running a blacktop zc converted to obd1
things checked:
timing
ecu
fuel pump
fuel injectors
fpr
blew air through fuel lines
fuel filter
map sensor
compression
getting no CELs
2 different fuel pressure gauges constantly read 65-75psi fuel pressure depending which pump is on the car, 2 different brand stock pumps. dont believe the rail is getting that pressure, i can turn the fpr pressure down and car will barely run, turn up the pressure and the car will idle fine, but the gauge wont change.
