I have a 2003 A4 3.0 Q with 98K miles. I went and put fuel in the car today and then about an hour later I was coming back home stopped at a light, all of a sudden the car started shaking and the check engine light started flashing. Got the car back to the house, popped the hood and noticed that the engine is shaking more that usual. Drove the car around the area, acceleration is now a little sluggish. Kinda putters a bit before feeling normal again. The tach still rests at normal idle position. Do I have a serious problem or could it be just bad gas?

Replying to: rowlandj (Jul 16, 2009 2:47 pm) I looked in the Audi manual as well and it says that if the check engine light comes on and starts blinking the way it is now that it's a faulty cat converter. Also the person that checked the computer said that cylinders 2 and 5 are misfiring.

Replying to: gregaudia4 (Jul 16, 2009 3:05 pm) Engine mis-fires and bad spark plugs/coil packs will basically send raw gasoline into the exhaust and ultimately damage the converter. I believe that if you fix the mis-fire issues that should help in that regard. A good run at full operating temperatures will also help once you fix that issue. You should not drive the vehicle until this is resolved that is why the engine light is blinking and not just remaining on. If you fix the mis-fire issues the blinking light should go off but you may still have a solid check engine light due to the evaporator issue. That fix may be made after the fact but if you want to save expensive repairs to the catalytic converter you should fix that mis-fire matter immediately. |
