Hey,

My check engine light came on 2 days ago and i had no idea why. But Yesterday while i was driving on the expressway i noticed that while trying to floor it past a few slow drivers my car (an automatic) would drop in RPMs right before it would shift into the next gear. Not a lot, only like 2-300 RPMs but it still dropped. It would then climb back up and shift. Is this a transmission problem or a computer problem. I did this two or three times while driving yesterday to make sure it wasn't a fluke and it happened each time. I have to take the car to my mechanic for final diagnostics but i am trying to figure which way this is gonna go. Any ideas?

thanks

The check engine light may be coming on due to a transmission problem. My check engine light would go on and off in my old 95 GT auto. Turns out the lock up function in the torque converter was broken. I did not have it replaced because of the cost, so I had a chip burned at a local performance shop that shut off the lock up function. My check engine light went off when he did that. He also informed me that if I replaced the converter, the light would have gone off, but the chip was cheaper. That was my story....

Go to autozone, they'll read your code for free. At that will narrow it way down and give you a clue.

Before you spend money at a shop I would suggest you have AutoZone pull the code and post it here.

Also check the transmission fluid level.

Its my cats. My mechanic says that my computer has to be retuned to accept the new performance parts. Either way the light is off.
