Hesitation No power lots of noise befire 4.5k RPM
Just thought I'd post this for future reference.
I have been struggling with lack of power, hesitation and generally running like crap below approx. 4.5K RPM.
Spec;
CA18DET in an RA23 Celica
Stage 2 H-Dev
GT28R
Exhaust
FMIC
MBC
Air Filter
NO Dump valve
After checking all the usual suspects, AFM, Coilpacks, Air leaks etc etc, I discovered that my Inlet Manifold PCV was stuck half way, causing a boost leak.
It was such an easy check and easy fix, I can't believe I didn't check this first! Hindsight and all that....
