Engine Performance problem
1996 Subaru Impreza 4 cyl All Wheel Drive Automatic 180K miles
My Impreza Outback seems to have an overall low idle speed (only about 100-200RPM)
Prior to this problem I had some misfire issues in the fourth cylinder, but only during the winter, and shortly after that I started getting an EGR Flow Malfunction code which prompted me to ultimately replace the valve. When I operated the new valve the engine chugged and died like it should. Most recently though the speedometer cable broke. The mechanic I took it to removed all the broken parts of the cable that he could and the vehicle still shifts and drive fine thanks to the two digital speed sensors I was told it had as well.
The problem still persists and I'm not sure what else to check. The fuel filter was recently replaced as well and the intake is clean all the way up to the throttle plate.
