Check Engine Light
Ok so my check engine light came on today, got it pulled at Autozone and it was P0442 which is the gas cap. But it wouldn't let him clear the code and it took him like 10 tries to get it to read. I don't know if something is up with my computer since the BL or what. Any one have any ideas, I have both battery cables unhooked right now to see if that will do anything, the gas cap was kinda loose so that might have been it.

Trent, it could be as simple as replacing the gas cap or you may have a hole in your EVAP system. Either try what your doing by unhooking the battery or you may need a new gas cap, Make sure the one you have now is on correctly.
Or it could be you have a hole in your fuel vapor lines going to the charcoal canister. Try the cheap options first...gas cap etc.

The code should have cleared no matter what, it would have came back on if the problem wasn't fixed. I hope it was a problem with his code reader, not my truck.

I looked and it was just like stock, no pinching or anything. I'm gonna extend it anyway, better safe then sorry. I know 2-3 guys that didn't have to extend theres and its been working fine for over a year.

Trent, next time you want to reset your PCM, you don't have to wait 30 minutes. If you turn on your headlights, then remove the negative battery terminal, it will reset in a matter of seconds. The headlights provide a current path to discharge the filter capacitors on the unswitched 12V line in the PCM.
You can also touch the negative battery cable you remove from the negative battery terminal, and touch it to the positive battery terminal, and it do the same thing.
I remember you saying you had your bed off lately, the fuel filler tube could be causing your CEL.

If you just unhook the battery, it does take awhile, because there is no current path to discharge the filter capacitors, other than leakage current in the PCM.
