I noticed my Check Engine Light come on and I took it to auto zone. They did a diagnostic on it and it came up to be a leak in the evap system somewhere. It noted that it was a large leak. Is this a common issue for 2.3L? It is a 2003 XLT.
ive had this prob many times, my prob was the hose on the side of the "coffee can looking thing" under your bed. the hose is on the drivers side, see if one of those has popped out, if it has plug it back in..clear codes
