I have a 2002 Chevrolet Impala with 73,000 miles on it. Last night it started to hesitate when I push down on the accellerator. Normally this car would take off with power, now it seems as if it is straining to go faster. The RPM's go up but the car is not moving any faster unless I let off the accellerator a little bit. Could this be the catalytic converter?

Doesn't sound like the catalytic converter, and more of a transmission slipping problem. I've had this problem on an older 1979 Datsun 280ZX which had a slipping transmission. Gunning the engine would not cause it to go faster and the only way to go faster was to ease up on the gas to allow the transmission to engage. Take your car to a mechanic because your transmission is the problem. Also, check your transmission fluid, as being low on this will cause the transmission to slip as well. So much for buying an American car.

well it sounds like your catalytic converter is not your problem, so the problem seems to be a bad torque converter. The other possible solution to your problem could just be a lack of fluid inside the trasmission, if it is low you should probably get the transmission checked anyways by a specialist because a transmission is completely sealed and if it escaped then you have a leak and will do no good to put more fluid in it, but the problem sounds more like a locked up torque converter

Definately not the catalytic converter.
Sounds like you might have either a torque converter or tranmission problem. Can't pinpoint what it might be with your description, but I'd have a reputable transmission shop look at your tranny and see if there are any stored trouble codes that don't constitute a check engine light condition.

Sounds more like the transmission slipping. When the catalytic converter plugs up, the engine slows down because there is no place for the exhaust to go.

Do the engine RPMs rise? If so, you could have a transmission problem. Try manually shifting the transmission and see what happens.
Also, check the fluid level in your transmission.
Also, when was the last time you changed your air intake filter?

Check the O2 sensor sometime you can have hesitation due to this being faulty if may be in need of a tune-up. clean your battery terminals you may not be getting the right amount of juice,
check all fluid levels especially the transmission. Spend a couple of hundred if you can spare and go get a diagnostics test done on the car. I would have to agree with alot of the other guys that have answered your tranny could be hooped.

My suggestion is to take it decrease back to the same save to substantiate it isn't the same difficulty. that is feasible that in the cat. conv. fix, the a number of connectors to a sensor would gotten free and brought some undesirable connection. in spite of the undeniable fact that, in the adventure that they declare that that is a sparkling difficulty and not in any respect with reference to the previous fix, request a replica of the codes saved if feasible on the artwork order. Then tell them thanks for checking it out and that you'll reschedule an appointment to have them do the upkeep or some thing like that. in spite of the undeniable fact that the plan is to get a 2d opinion from a respected fix save and get there feedback on the precedence. also supply them the fix history with a purpose to study and study what they got here across. As far your question in the adventure that your motor vehicle has 2 cat. conv. i'm assuming that your engine is a V6. that signifies that there are 3 cylinders in line with cat. conv.

I would look at the air filter, fuel filter and transmission before i looked at the catalytic converter

When you floor it do the rpm,s exceed 2000. if not the trans might be ok and the problem lies in restricted exhaust or plugged fuel filter.really need to have it ck by a tech to get a accurate diagnosis.

MY QUESTION TO YOU IS WHEN WAS THE LAST TIME THE CAR HAS HAD A GOOD TUNE-UP. WORN OUT IGNITION COMPONENTS CAN AFFECT YOUR CARS PERFORMANCE DRASTICALLY. I WOULD ALSO RECOMMEND REPLACING YOUR FUEL FILTER AND RUNNING A GOOD FUEL SYSTEM CLEANER SUCH AS LUCAS OR SEA FOAM...LASTLY I WOULD RECOMMEND CHANGING YOUR AIR FILTER AND SPRAYING OUT THE THROTTLE BODY TO ELIMINATE THE POSSIBILITY OF VARNISH RESTRICTING THE FREE MOVEMENT OF YOUR THROTTLE PLATE.
