autozone... do they have them in canada? more importantly in winnipeg?

 

Back to the exhaust question, I did find a company that makes true duals for my truck at least, I'm not for sure if they make one for a 4.7 or not, but Spintech does. Its just high

 

thanks man. but im just gonna keep this exhaust for now.
so i used the sticky thread and ran the code. mine is P0441.

P0441 (M) Evap Purge Flow Monitor Insufficient or excessive vapor flow detected during evaporative emission system operation.

could anyone help me out and explain how to fix this and what parts i need. the sooner the better i get nervous when my truck has the CEL on. thanks

 

don't think there is autozone in canada but try Parts Source....

 

It means the purge solenoid in not working, or the vacuum to it is missing, a quick explanation is. After the leak detection pump passes all its tests, the PCM closes the vent valve and turn the purge on to see if it will create a vacuum in the tank , it has already check for leaks using the pump , now with the purge on and no leaks it should see the pressure switch go from closed to open . If not then it assumes there was no purge flow , hope this helps

 

thanks. helps a bit. if you could tell me where it is and how to fix it that would be awesome. and do i need to pick up any parts? i also heard this can be caused by over filling your tank. which i do.
