guys, I have my 2001 A4 (1.8T Q auto) check engine light on yesterday.
code from autozone is:
P0322 Ign./Distributor Eng.Speed Inp.Circ No Signal
I also observed that EPC comes on several times (check engine light always on), and when EPC is on, idle rpm raise to 1100, normal is 750, and car has noticable reduced power. and mpg super low.
When EPC is off (only check engine light on), car runs almost close to normal and maybe a tiny little bit power loss.
Anyone can help me on this, which sensor or part should be fixed?
thanks a lot
Scott
