The reduced engine power has been coming up off and on. It's not in a regulatory pattern, some days it lasts a day others a few days.. It exceeds no more than 4 days at a time. I just had a fuel injection & oil change done 24hrs ago. I have an 08 Chevy Impala. I want my car working 100% and for the check engine light to go away... Pleas HELP!

If the check engine light is on then hook up an OBD reader (which is pretty easy to do and a lot of parts stores do it for free) and find out what the problem is.

there is a large evaporative leak. keep away form ottozoo, they dont have the brain power to actually diagnose a light bulb., their job is to sell parts., if they sell you the wrong parts tough.Take it to a qualified repair shop that does a lot of GM work or the dealer.

I posted a solution for another person with an Impala that had a problem with the car intermittently not starting. If you can find that post and follow those instructions that will solve your not starting problem. As far as the check engine light coming on the other persons are correct. It is much better to go to an Autozone and have them pull the trouble codes. Once you have those and can post them then one of us can give you some advice as to how to solve the problem. You can also take it to a professional garage and they can check it out and give you more detailed one on one professional advice as to what the problem is. If you just guess at these things you can spend a lot of time, money, and frustration for nothing. Good luck!

The fact that the oil was low would not be from the oil pump, but from wear in the engine. If it is not smoking when you start it or as you drive, you can probably keep it running by just keeping the oil level checked at each fuel fill-up. As for the car shutting off, you didn't say if the engine seized or got real hot. A low oil pressure problem should have triggered a warning light before the problem got to the point where you lost the engine.

If the car ran after you added the oil, you got lucky and need to always check it.

On my 2010 Silverado the message center says engine power reduced, service stabilitrack and service traction control system. What would cause these messages. It started after sitting for a few days


The fault codes have nothing to do with it sitting for a few days. There are sensors that work with your ABS brakes and TCS to help your car maintain control when corning briskly under load. You probably have a bad sensor on one of the wheels. Recommend you get the Haynes manual to see exactly how to test and replace them. A multimeter will help too.

I have a 2010 Chevy impala. Reduced engine power and check engine light also comes on but won't stay on. Codes are P2138 P2122 P0455


Hi Rosalee_IM,
The codes your vehicle is storing are for low voltage from your accelerator pedal position sensor and a gross evaporative emission leak. The code P2122 and P2138 are directing you to test the accelerator pedal position circuit and/ or sensor. This is the cause of the reduced power concern you are feeling.The P0455 is telling you there is a large leak in the evaporative emission system. The most common cause for this code is a loose or incorrectly installed gas cap.I hope this helps clarify the concerns you are experiencing. If you'd like more information on how to trouble shoot the problems,drop me a line. Please include the model Impala you have,(LS,LT or LTZ) and the engine size. I will do my best to get back to you as soon as possible.Thanks, Chuck
