I have a '87 toyota 4x4. When I hit high rpm I hear a congested noise and sometimes lose power, but when I let off the gas I feel the power come back. Any Ideas? Could it be the clutch?

I'm not exactly sure, my pickup doesn't have a tach. but if I had to guess, probably around 3-4000 rpm

Might be your fuel filter needs replacing.

probaly not vaulve float then. i agree with brianR. check your fuel presure... doesnt have any check engine light does it?

No check engine light, I replaced the filter maybe six months ago, could it be the pump? Or can the filter go bad that quickly?

sure could be the pump. throw a fuel presure guage on there to test it. there kind of pricey and a bear to change so you want to be sure its bad before you replace it.

Yeah I just replaced the pump in my 92 honda accord, I don't ever want to do that again. I'll check it out, thanks for the info.
