i had a flowmaster muffler/duals put on my truck and ordered an AF1 today.. do these void warranties?

 

Not unless the dealer can prove that that specific aftermarket part caused damage to a warranteed part. The short of it is: Mods don't void warranties, dealers do.

 

Put it this way...

If your drivers window stops working... they will not void your warrenty on it because of the AF1.

Now if you burn a whole in your piston because you were running lean and you had an AF1 on the intake, you bet they will void your warrenty.

is this a common problem with AF1?

 

The answer is NO. None, and I repeat NONE of the CEL lights on the 2004 models that experienced this issue( including mine while I was participating in the R&D'ing of this unit) was ever a direct result of the vehicle actually running lean.
There is a safety factor programmed into the ECU's that causes the CEL light to illuminate without the vehicle doing so. You should do a search for this information that was posted in the Chips section by Mike Troyer that will explain this issue to you in detail....
