Audi A4 1.8T Quattro Engine Stall Problem
Got my 98 Audi A4 1.8T Quattro 2 months ago, and slowly found out some problems with this old but still performing guy. The most annoying problem is the engine may just stall when i break at the junction, although it didn't happen frequently. Before that, the car will just shake for a short while. I just changed spark plugs, fuel filter and etc recently. Could it be caused by a dirty throttle body or the mass airflow sensor, or both? My technician told me that i got to change the throttle body, however, it is just so expensive. Can i just simply do some cleaning of it?
Thanks for any helpful suggestions!
