Hello, I have a 1998 Nissan Maxima SE with approximately 75,000 miles on it. The check engine light on my dashboard is illuminated. I took my car to a mechanic who ran a diagnostic test. The test said that the problem is a loose gas cap. I purchased a new gas cap and the mechanic reset the onboard diagnostics computer. A few days later the light came back on. I took the car back to the mechanic and he ran the diagnostics again with the same results. Clearly the problem is not a loose gas cap. I have read that the problem could be a small hole in one of the hoses for the fuel system. I would like to know if the fuel system hoses could be causing this problem and if so, approximately how much it would cost to fix this issue. Are there any other problems that could be causing this to happen? This is a major problem for me because I live in Chicago and need to pass the emissions test or they will suspend my drivers license.
Thanks for the help, Billy
