Hey guys I have a CEL code 90 i know what it is what I don't know what I can do to fix it. Pleeease help out guys. I have no clue on how to fix it.

90 is something wrong with the fuel canister right? i threw that code after i installed my skunk2 manifold. you should check and see if the lines are not crimped or bent in weird ways. reset your ecu and see what happens. if not then im not sure, good luck

I think that it has somethig to do with that little round can by the battery. Maybee a vacum hose is clogged or something. Also make sure u have the gas cap on tight. If its loose you wont have enough pressure in the gas tank.

that would be the fuel canister

I'm not really sure, because it could be my fuel filter, because I just recently installed a fuel pressure gauge and maybe something is not tite. I also installed a fpr and had to replace my fuel line so maybe the line is too long, I just mad the gas cap tighter and resetted my ECU and drove around for a while and o check light yet, but CEL comes on a little while after so I got to see what's going to happen.
