1990 BMW 525i m20 2 problems?
Hello again members, My 1990 BMW 525 i has 2 problems I have a high idle after the engine is warmed up idle is around 1000-1200 and when it is cold it seems to idle fine maybe a little lower than normal any suggestions? The idle doesn't seem to hunt up or down.
The second problem is the heater always outputs heat to the passenger vents and I replaced the heatervalve and still have the same problem. What is the best way to check for the problem. It has the regular 3 dial knobs for the heater controls.
The car has 204,000 miles
