My engine light the one described as the Emissions Warning Light just came on and stays on. I checked the service manual and it says if you change the tire size or the Exhaust system it could trigger the light to come on. I have done both, put the new Magnaflo Cat Back system on and changed the Wheels to 22 in. all around. Does anyone know if there is a procedure to compensate for those changes I made or will it have to go to the dealership to have the computer reprogrammed?

I didn't have any problems with the Mangnaflow cat back system and I don't recall others saying changing the wheel size affected emissions.
When my light came on, I did have to change my catalytic converters - after 60 or 70 something thousand miles.

I agree that many here have similar mods with no issues so I'm not sure I would blame the wheels or exhaust just yet.
Hmmmmm, how about the gas cap? Can that cause the same light? I know it's an issue on some vehicles. If the cap is a little loose and the tank does not pressurize correctly it could set a light. Check the tightness and the condition of the cap, pull the fuse to reset the computer and drive it around the block.

Check the O2 sensor
You could also have an Oxygen sensor going bad - there should be a code set in your computer pointing to a bad O2 sensor if that is the culprit. Most have a lifespan of about 60,000 miles, but I've had them quit far sooner.
