Wide open throttle prob

[sadiemuu]

Hey, I am an old member but must have gotten booted for not logging in.

I have a 97 ranger with a 4.0. It runs fine when cold, but after it warms up, it loses power at about 30 miles per hour at w.o.t. It will spin the tires from a dead stop and I can drive it all day long feathering the throttle, but if I floor it from a dead stop I hit about 30 and it's as if a rev limiter kicks in and bogs. Thanks in advance, Matt.

Hi my-friend:
I had a similar problem and much to my amaizment just cleaning the mass airflow sensor made the truck run like a brand new one! I am far from any kind of auto tech but that sure worked for me. I have a mechanic do all my work including oil changes.

That was the same thing mine did and that fixed mine
