I brought my toyota solara 2002 to the dealer for diagnosis "check engine light on". The dealer suggested to change the canister that worth $ 300 bucks! I did try to change the canister cap but in a few days the warning light popped again. Any other suggestion? Thanks.

nurzes, I can help you because Toyota's are the name of my game... BUT... I need a little more info.
Since you went to a dealer, you paid a diagnostic charge and for that they must have told you a code (or codes) that your Solara put out and why your CEL came on.
Need to know what engine, and vehicle milage too.
