i have a audi a6 that is causing me problem after problem. i took it to autozone to see what codes were coming up, it said the crankshaft positioning sensor is bad and cylinders 1,2, and 5 are missing firing so i replaced the cks sensors and the car still wants to idle at 1200 rpms and shot off on me while im driving. the epc light and the check engine light keeps coming on. please hlp me in anyway possible. thank you and have a good day
