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......

Probably, but dont know what car you have... If it fixed the problem I'd call it good...

Be like my wife, just leave the cap on the gas pump and drive off...
