I had just installed my ported throttle body, did the alignment check from vcds, cleared codes.. ran car a about a mile. Epc, check engine and battery light came on. Lost all power and steering. Luckily I was next to oreillys. Checked battery, starter and alternator, all good. Cleared codes. Drove home. No issues or codes, opened her up a bit. Still no codes or epc issue.
