I have had a recurring problem and am wondering if anyone else has had the same one. Since December 12, 2002 the service engine soon light has come on 5 times. The last time was February 22, 2003. I keep getting the same code P0442 which I am told has something to do with the fuel system. Probably a leak. I know that if you leave the gas cap off or loose that can trigger the same code but everything check out and I still get that light glowing in my face every 2 to 3 weeks. The dealer fixed a loose wire on the computer (PCM?), replaced the gasket on the gas tank for the fuel pump, and a solenoid under the hood, and it still came on. The last time I took it in the dealer called GM and they were no help at all. GM had no suggestions as to what the problem might be or any remedy. Help!
