hi, all
i have replaced a valley pan gasket , and while i was at it, i clean the tb and intake manifold on my 02 x5 4.4.
after everything was put back together, i noticed engine idle dips to about 300 and comes back up to normal idle speed, when coming to a stop. it only happens when engine is warmed up, and when i put gear in D position. if i put gear in S mode, car drives just fine.
thanks for your input in advance.
