Why won't my 02 ranger 4.0 go past 3000 RPMs?
The engine starts and idles (a bit high). Won't rev higher than 3000RPM. It
seems to flatten out at 3000 almost lit its hitting a rev limiter. New plugs,
wires, coil pack and no check engine light. I've cleaned the mas air flow
sensor, I'm going to try the crank sensor next. Any other ideas would help.
I have an 02 standard cab base model and mine seems to have done that randomly a few time. It was brief and then it just stopped. Although it wouldn't run smoothly when you tried to accelerate. Unfortunately?, it only occured briefly a few times so I couldn't catalog all the little details of the problem. It hasn't recurred in many months.
Should have added that it's a 2.3 engine.
