Car Shutters, CEL, then runs fine
#13
you have a bad coil pack
I have a 98 A4. The CEL was flashing and engine running rough. Would smooth out sometimes. Want to a garage that work in Audi's, plugged it in to the scanner had to replace coil packs, plugs and wires. Runs like a champ. O2 sensor have there own codes. If it goes to long, you are dumping raw fuel into the exhaust system, the cats will go bad. You might get a code that states "bank 1 or 2 below ....." That is what happened to me.
