I went out to start my truck after work yesterday Tues. and when it started the check engine light was on, so i stopped by a friends and pulled the code maybe you guys can tell me whats up, i got home and then started it again and no light, but again today Wend. right after work it did the same thing and it is still on, the code was
PO541

Oh by the way, this truck is awesome, filled it up today and got 19.7 in town driving, but the fuel here is 4.13 per gallon (ouch)

 

hi

What the heck is that, its funny as it has just started to warm up here in NM and when i get in the truck to go to work it is out, when i leave it is on. I just went out tonight and its off.
