I am Scared to take out the Valve as mechanic told me the 2 Screws holding the Canister are very difficult to come out & its going to damage the Canister . Its not only this Valve there is another part which related to EVAP Purge Vlave & Canister which also need to be replaced. He told me he seen this problem before no of times , just replacing the valve will not fix the problem , LED will come again if i drive for 70-80 miles to pass emission test. Ttotal estimate given by him is 400-500$ ( 54 $ for Valve , 80$ Canister + 200 $ Related Parts+ labour ). I asked him to take out the valve & chek but he denied, i am computer person dont know much in car mechanics & never did any work on my own. Pl let me know if estimation given by mechanic is correct or not. If you are in NJ i can drive to your place on weekend if u can fix it for less..
Pl let me know , appriciate ur help.
Thanks
