I brought my 98 A4 in for rear wheel bearings and an oil change.
When I picked it up from the shop the Check Engine Light was on
and the car ran like CRAP. I brought it back the same day.
The code was the #1 cycl. not fireing. He replaced the coil still not fireing.
He checked the fuse that was ok.
ANY IDEAS, HELP Besides find a new mechanic.

 

describe how it ran. in as much detail as you can.

 

My wife drove the car home from the shop. She said it was skipping, no power, shaking and
the Check Engine Light was flashing. I talked to the machanic today he said he thinks it's the
power unit or power modual cost of about $400. Strange coinsidence the car ran great when
we brought it in to the shop.

 

Swap the #1 spark plug with another.

 

ack, just make sure she doesn't drive it on a blinking CEL. Can you get the exact code that the ECU was giving? There are many differenct misfire codes.
