2000 alero gas pedal hesitation as well as shut off when slowing or stopping


Usually the problem of hesitation is caused by a faulty throttle position sensor or low fuel pressure, and stalling is a dirty throttle body or faulty idle air control valve.
Is the check engine light on ?

Hi, i have a 2002 alero that is having engine hesitation ever since i got my ac fixed last week. was only slightly hesitant at first, but now it will barely go over 40-45 mph.thanks!


AIR CONDITIONER PUT LOAD ON ENGINE.IN ORDER FOR ENGINE TO CARRY AC LOAD YOUR ENGINE HAS TO BE TOP KNOTCH SHAPE.SPARK PLUGS + WIRES HAS TO BE GOOD.FUEL FILTER AND AIR FILTER HAS TO BE GOOD SHAPE.INJECTORS BEEN CLEANED.SEE YOUR ENGINE HAS TO HAVE FULL POWER TO CARRY AC LOAD.IF ENGINE POORLY TUNED THE AC WILL PULL DOWN ENGINE POWER THATS WHY YOU GET HESITATION.

Idles fine, but has hesitation and cutting back when you accelerate.


same with mine... exact same situation. I have an automatic, and when it switches gears the rpms may spike and/or it won't shift. further investigation showed that the transmission fluid was leaking thru a hose... add a half quart of trans oil and drive it to a mechanic unless you know how to check your level

Chirping when @3500 to 4000 rpms, 2000 taurus


3500 rpms is about 80 mph. Is this noise in 1st, 2nd & 3rd gear? Is check engine light on?
Chirping could be accessory belt noise. Spray them one at a time with belt dresing to see if it goes away and which belt is doing it.
