P0442 code w/ new cap My 07 corvette keeps throwing the P0442 code. I got a new cap from GM a month or so ago and it has thrown the code 2 more times. What is the next step to trace down this problem. Ive pulled the cover and looked at the lines they all look pretty good no cracks or anything. Thanks in advance
