View Full Version : Evap Canister

The check engine light came on on my 1999 Grand Am SE II, so I took it to Autozone and then said the problem showed an fuel evaporation problem. The clerk said that usually means a bad gas cap or evap canister. I changed the gas cap and I still have the engine code.

Both before and after the gas cap change, the light goes on and off.

The question is, is it most likely the evap canister? And if it is, how do I change it?

could be anything in the evap system...best bet is to take it to a shop, what theyll do is put smoke in the evap system or nitrogen and look for leaks...thats mostly all you can do to find it...anyone else wanna chime in with a better way?...

actually it is sometimes the rubber hose that goes from the evap solenoid to the intake, the rubber U elbow, but that system can find a leak as small as .020" so good luck finding it, i would go to a good shop with a smoke machine like Xtreme said.
