i went to autozone and hooked my truck up with the scanner, it came out to be two codes, the first one said : one large vacume leak, the second said: one small vacume leak. and im cant figure out wut the problem is, i had a cold air intake on the truck before but now i have the stock unit back on and right now i have a dynomax muffler with a dump, none of that stuff could cause that problem i dont think, anyone else had these codes??

 

The codes weren't exactly for vacuum leaks, but rather EVAP leaks. As in evaporative emissions system leaks. Check under the hood, and on the driver's side you will see a vacuum line with a green plastic cap on it. Make sure none of those hoses are cracked and then check under the truck - near the fuel tank you will see the charcoal canister. Make sure none of the hoses at the canister are cracked. I would be willing to bet you will find it in one of the two places.

 

check your gas cap to make sure its tight, thats the code that it throws for aloose gas cap
and its the easiest thing to check

 

yup thier were two hoses on that black box by the gas tank that were either cracked and almost completely off, where do i get new hoses, just the hardware store or wut

 

jsut cut them back past the cracked part and slide a good portion of the hose on instead, there is usually enough slack in the hose to do this 4-5 times
