I am very well aware that the leaks can cause this problem, and my first guess was that the tank ventilation valve is stuck, but replacing it did not do it. Also, one by one, i took every vacuum hose off the manifold and plugged them up- did not help either.
ISC was taken apart and checked- everything looked very well. This car does not have the 14th pin in the diagnostic socket
The idle got even worse over a week. Now the fluctuations are in every mode - driving in traffic, reversing, parking. Also the CU gives me the " airflow mass sensor signal- voltage too high" constantly. I checked for the short circuits in wiring and found none. New air flow meter is ordered so i will have to wait and see what happens. Any comments and advice are very, very welcomed.
