well my monte seems to have a "that time of the month" section were crap just goes wrong.. and its frustrating. my check engine light came on about 2 days ago and is still on right now. so i pulled the code today after work with a OBII scanner. and i got a P0446 its a evap failure or malfunction.. what should i look at replacing??

 

Did you gas up recently? It could be a loose gas cap. It could also be a restriction in the tank vent, or a malfunctioning vent valve.

 

i did gas up like 90 miles ago and i checked the gas cap its on good... i changed my fuel pump a few months back and had a small ishue with the fuel pressure sensor on top, but managed to get it to work. now is this part the same thing?

 

The vent valve is #22 in the diagram below. A bad eletrical connection or valve could cause a P0446 code. An obstruction in any of the hoses leading to the canister or a plugged canister itself could also throw that code.
