1. i looked at the code inside of my glove box and the last line says "BC/CC U 382E 92H" is that the paint code? its like a tan stockcolor.. i was gonna buy a GM touch up pen that said something sandbut wasnt sure
2.my service engine soon light has been on for a while but i dont think anythings wrong. i'm gonna get a engine diagnostics check at autozone sometime this week, but does any one know any common problems?
3.also my oil pressure gauge doesnt work. any common problems there?
4. i'm hoping to sell it soon. is thereany easy things to do that can up my asking price besides the above stated?
