Replace just ignition coils ???
2008 audi A6 3.2 quatrro with over 210K miles suddenly just started with LOUD ticking sound. Initially thought it was the timing chain tensioner that needed replacing.....BUT.
After adding some seafoam to nasty old oil, changing the oil......the engine started VERY roughly. In order to keep the car running you have to step on gas. Drove it this morning and NO power at all. Got these codes this morning: Audi Codes PO300- random/multiple cylinder misfire PO068-mass airflow sensor, throttle position sensor and the Manifold pressure (MAP) sensor. P12A1- Fuel rail pressure sensor-signal low P0346-camshaft position sensor A circuit range/performance (bank 2) P0172- Fuel trim, bank1 system too rich P0301-cylinder 1 misfire P0302-cylinder 2 misfire P0391-camshaft position sensor B circuit range/performance (bank 2 ) P0306- cylinder 6 misfire P0305-cylinder 5 misfire Should I just replace ALL the coils and clean air intakes or MAP? Thank you in advance for any advice/help |
