[QUOTE="Vman, post: 444328, member: 22091"] There are a couple other common locations for large evap leak. I had to chase down evap stuff myself when I got mine. Don't overlook the most common cause: the gas cap. There is also a module on the charcoal cannister called the ESIM which also has an o-ring that can go bad. I had to replace both the ESIM and o-ring to fix mine. There is also a vapor line that goes into the gas tank that likes to crack: [ATTACH]120420[/ATTACH] If you're having misfire issues, just replace your plugs and wires first and then your coil pack. You probably have no idea how old those items are and they're critical to performance. I had a cylinder 1 misfire when I got mine and luckily during my inspection found (by smearing my greasy hands all over the porcelin part) a hairline crack in it. Used that to my advantage to get another $500 off asking price. Your traction control light is probably a wheel speed sensor that has gone bad. These problems probably existed before you bought it, and whoever owned it before you just didn't want to spend money to fix it. [/QUOTE]
