My 2000 Prairie loses power goin up hill and starts to put wen throttle is fully pushed ..could this be cause belt is loose and should I change spark plug

SOURCE: loosing power

Wow, I just went through the same problem and guess what it was a clogged converter and a bad oxyegen sensor. The garaged fixed it up for me by putting an eco converter on it and a new O2 sensor. I have a 2003 Chevy Impala,V6 3.8 engine. Good Luck!!!!

check you spark timing...the crank sensor.  Is a check engine light on?

Check for blocked/low fuel flow. ie fuel filter or failing fuel pump.

SOURCE: it loses power on acceleration and serious loss of power on hills

sounds like a clogged fuel filter. you need to have the engine pressure checked for leaks, you can rent the pressure checker at autozone, it connects to ur radiator and u pump pressure into the cooling system if u find water leaking around the head u know u have a blown head gasket. if ok then check the cylinder compression should beable to rent this also. it screws into the spark plug holes has a gauge on it. alternator problem w/ the light is probaly you need to tighten the belt.hope this helps!!!

Testimonial: "thanks very much. i'll check that out."
