86 4runner 22RE
Major hestitation starts around 3500 RPM and car will not rev above 4000. Car idles fine. Replaced injectors, fuel filter and cut off the cat which was running red hot. Still hesitates. Timing is way off as the revs increase so 2 questions.........what is the equivalent of vacuum advance on EFI and how is it regulated. I am leaning towards the ECU or ignitor but could sure use some direction from a more experienced 22RE wrencher. Thanks in advance
