i have been experiencing a loss of power and the car won't go over 25 mph ,it does this after the engine is warmed up and it acts this way for only a few minuites ,but when is does it is very anoying and seams like forever. does anyone have some ideas of what is happening ??

Does it start when idling, coasting, accelerating, cruising or...?

Cheers

the problem starts after the car has been running and is warmed up , and starts wile driving and/or restaring the car after making a stop. i hope this helps.

Does the engine miss and sputter or does it just refuse to rev up when this happens?
steve

when this happens it does both ,sputters and back fires smells like unburnt fuel and will not rev up above an idle. then it clears up and is back to normal.

Sounding more and more like a bad cat. Hook up a gauge and check exhaust backpressure when it's misbehaving.

Have you checked the ECU for any codes?

Failing catalytic convertor?
