What would cause a 2002 infiniti qx4 to sputter and not rev up past 3000 rpm
Low fuel pressure or supply, plugged exhaust system, cam or crank sensor erratic signals, rev limiter malfunction.
Not really, I've had a a fair number of rigs that came in and no codes were present but did show erratic signals from either the crank or cam sensors, had a Chevy truck show both and still no code.
