Check engine light. Chip? Filter?
#1

So I just bought a 1999 Ford F350 Dually and it has a check engine light on. The guy I bought it from says that it is chipped and it has a K&N filter and that is the reason the check engine light is on. How can I check if it has a chip without pulling the computer or dash or...wherever the chip is apart? Or what other things could the light be for? It has an exhaust leak, does that cause the light to go off? Other then the exhaust leak the thing runs fine and has plenty of power.
Thanks guys

Your run of the mill autozone code reader will NOT work.
Where is the exhaust leak?

Yeah my buddy has a good code reader Im going to ask to borrow on monday, I thought I would ask about the chip here first. The exhaust leak I believe is where the header couples with the...Y pipe? The flange doesnt have a good seal I guess. Unless that completely wrong I really havent looked at it much yet. I bought it a week ago and havent had time to go through it besides cleaning the interior.

As mentioned, if the SES light is on and stays on all the time, the only way it would be related to the chip would be if the chip is damaged or the program on the chip is damaged or incorrect for the application.
It's not that big of a deal to pull the chip out and see if the light goes away. Just make absolutely sure that the ignition key is in the back seat or in your pocket before you fiddle with the PCM, particularly if installing/removing a chip. At least that would verify if the chip itself is the problem and provide a more defined direction to investigate.
Definitely check the DTCs. Those are invaluable when it comes to diagnosis.

My edge evo will trip my light when it's set at above 80hp...the code is a low oil supply to the injectors, meaning nothing to me cause it runs the same, when it's on. I just use the evo to cancell the light. But when set at 60hp it doesnt come on. Since i have been using full synthetic it dont' come on near as often. Just cant afford stealth pumps and a tony wildman tune yet, and the evo was FREE! So i am dealing with it.
