I noticed my car would idle rough with the gas cap on, as soon as I remove the cap, the idle smooths out. The cap on the car is non vented. Can I just replace the cap with a vented one and call it a day?
Thanks.....
Not sure were it could be. Not sure if even the car came with a vent line. Replaced the fuel tank yesterday. The only lines connected to the tank were the 1 fuel line and the filler neck......
