Need help with 2001 Toyota Celica GTS Sign In

My teenage son has a 2001 Toyota Celica GTS 6 speed. It has 207,000 miles on it. Recently the check engine light came on, and it spits and sputters when accelerating and shifting between gears. While you're accelerating, the check engine light also flashes. Once in 6th gear and maintaining a constant speed, the car runs fine. The check engine light stays lit but does not flash. We've tried changing the spark plugs and putting fuel injection cleaner in the car, but it still has the same problem. Any help would be really appreciated. I would like to avoid a costly repair if possible as I just had the clutch replaced a month ago and that cost me over $ 1,000.00. Thanks so much in advance for your help!!! Smile

Re: Need help with 2001 Toyota Celica GTS Sign In

 The "check engine" light is an indicator for a system that monitors many electronic functions in the system, also called the "malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.

Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we can be a lot more specific about what your problem may be.

Sorry I should have told you this. We did have them check it at two different places, one Auto Zone and one Discount Auto. One reading said it was misfiring on cylinders 2, 3, & 4. The other one said it was misfiring on cylinder 2 and also showed the catalytic converter??? The readings were done within a day of one another. :o(

You have severe misfiring and you going to have to have some tests run to determine the cause. With that kind of mileage it could just be worn out mechanically.
