Where to start with this code? Drive a 2004 MDX Touring with a 132000 miles, car is running fine, with the exception of the MIL light coming on. Replaced the gas cap, my husband resets the code and then it resets every 4 to 5 drive cycles. The code is so vast, it could be any number of things. Anybody else ever have this problem or suggestions on where to start? Thanks!
