What is your question?
Hi Guys. I just bought a 2003 Nissan Altima SL 2.4L engine 2 months back with 102000 miles on it for $5500. have driven 3000 miles on it. Last week, my service engine soon light turned on and it has remained on for the last 10 days. Went to my local mechanic. He checked the error code, did something called a smoke test and told me that i need a new charcoal canister, vent control valve, vent bypass valve and purge valve. and gave me an estimate of $1200. I don't want to spend so much money on my Car. Any help/suggestions? The error codes are listed below: - P0455, P1448, P0441, P1456. Any suggestions of good mechanics who can do it cheaper? Please help.

have you tried a new gas cap?all your codes are pointing to the cap.put a new cap on it and get AZ to clear codes,and drive it,to see what happens.this is the cheapest,so try simple things first.if your cap is cracked,not on tight,or the gasket is buggered up,you will see these codes.wont hurt to try.post results.good luck.copy and paste the below links and read probable causes.

Alright. Thanks. I'll try that first. And then get the code cleared by autozone. And see what happens.
hopefully,no more light.good luck
