Having problems with your 2004 Ford Ranger ?
2002 RANGER RUNS OK UNTIL RPM GOES OVER 3000 AND THEN IT LOSES POWER. NO CHECK ENGINE LIGHT-PLUGS WIRES ETC REPLACED RECENTLY NEW AIR FILTER, CLUELESS.
Check for a restricted or plugged exhaust system, you could have a catalytic converter going bad... If you have no misfires and all ignition components seem to be in good condition then I would suspect maybe a issue with the exhaust system...
