My dad recently purchased a 1988 740 with a five speed and after 2 weeks it developed a problem where after driving the car for a little while it will idle really high (2500 rpm) like the iac valve is stuck completely open. I hit the valve with a hammer when it was doing this and the idle came right back down to normal so I assumed it was a problem with the valve. Now we replaced the valve and its doing the same thing. Is it possible the valve is bad again or is there something else that would be telling it to idle high?
