I am unable to get over 3500 RPM while running, although in neutral I can get over 6000. I have narrowed the problem down to intermittent output on all cylinders and at least 1 cylinder dead. I have replaced coils, caps and leads but the problem still persists. The engine runs fine to 3200rpm but then will not gain anymore power. Not to sure where to look next
