take a look at your sway bar arms are they fully extended like pulling on the sway bar The rear ones are the proper length to go on the front for a 2,5 inch lift. And get some new for the back,
Had most of the same issues,plus mine would shift into nuetral and set a camshaft code.put a scanner on the alternator output found out the alt diodes were shot and it was putting a fuzzy 1/2 AC current changed the alternator no more problems.
