2.7 L engine - recently replaced water pump which failed and while at it I also replaced the timing chain and primary tensionser. Now, after driving for a while (20 minutes or more) the idle drops at stops to between 4-5K and occasionally stalls, but prior to this (even after engine fully warms up and reaches closed circuit) there is no problem at all. What could be the source of this?
