2001 Chevy Prizm: Sluggish acceleration, recently replaced Cat.

Hello,

I have a 2001 Chevy Prizm. Initially, the check engine light came on. I was told it was the cat. The car began to run sluggish and the R.P.M.s were eradic when I pressed the gas pedal in neutral. When I drive, the car wll become sluggish and not able to climb hills. I use premium and Lucas but this has not seemed to help. Everything I read seems to be directed towards the mass air flow sensor. Could this be the problem?
I look forward to your response!
Thanks,
Tom

    Follow up note:



    It was the mass air flow sensor, the electrical component at a cost of $149.00. The car runs great!

    Have you ever changed the fuel filter at all most cars require them to be changed around 30,000 miles if the filter is pluged it will cause power loss also when climbing hills and its a cheap fix is the check engine light on at all ?

My 2001 jimmy has a slow and sluggish takeoff and acceleration speed. Wiring harness was melted apart from busted heater core hose.would a bad connection cause this problem.


Usually not. If it is shuddering while accelerating it's usually a plug wire. If you have a check engine light on then start there

My chevy impala lacks power and acts very bad sluggish while accelerating


Any check engine/service engine soon light? Could be a clogged catalytic convertor, search for cleaning a catalytic convertor. Try cleaning the mass air flow sensor, it is before the throttle plate. If you are losing coolant, your engine is prone to this, it could be leaking intake gaskets.

Sluggish accelleration


If the check engine light is on, it could be one of several different sensors.
Otherwise, I would want to know what base fuel pressure is to start with. And has the fuel filter been replaced in the past couple of years ?

Problem started suddenly two days ago. Engine is 4cylinder - Autozone diagnostic showed codes p0441, p0442, p0446. Replaced spark plug wires and disconnected battery to reset computer. Now - no check...


PO441 ,PO442 codes have to do wit the oxagen sensors, If there is a problem with both of them,Or your cat is pluged up ,The car will not run (Properly)

Car is sluggish, Low Acceleration, Check engine light flashes, Code reader indicates #1cylinder is out


Of course your car is sluggish, cylinder number one is misfiring, that is why the flashing check engine light, if you continue to drive this car this way you risk the exhayst system overheating and starting a fire. Ge the car tested for the cause of the misfire asap.

My 1999 Chevy Prizm has the check engine light on - although I have had no mechanical problems with the care, it drives fine. I have lubed it, and gotten gas recently, but light still stays on.


Your check engine light is an emissions warning. Your vehicle will not pass smog with the engine light on. You can go to kragen or other auto parts stores and buy a GM code reader for it. Though it runs fine, its telling you that a sensor or something is bad.

2001 Chevy prizm with persistent check engine light, have replaced multiple sensors and canister. Has been on for four years running, current error code is P0441


4 years? you really need to find a mechanic that knows what hes doing. if you have replaced the canister and purge solenoid valve (muliple sensors? you realy need to be specific on what has or has not been replaced ) most times the hoses are not installed properly on the purge solenoid, or leak. the hose with the green cap/test port should be closest to the electrical connector.

Check engine light keeps coming on


The 1st thing to do is find out which one of over 100 codes is stored in the engine computers memory, whenever the check engine light comes on a code for that problem is stored in memory. You can go to any Auto-Zone parts store and they will run this code read test for free, then post them back here and I will help figure out what has gone wrong.
