Help with 2002 V6 Coupe & PO455 code
My 2002 3.8L V6 Coupe's Service Engine Soon light is on and also the Check Fuel Cap light is on. The code that was given was a PO455 (gross evap leak). I tried a new fuel cap, as my stock cap was pretty worn out. I reset the battery, but about 120 miles later the Service Engine Soon light comes on and another 50 miles or so, the Fuel Cap light comes back on. I assumed that because of the GROSS evap leak (as opposed to a small leak) that it was something larger than just the fuel cap, but I never smell gasoline or anything. Is my next step the fog machine to find the leak?
Thanks in advance for any help or just reaffirming my denial.
