I just got the car so nothing has been done to it. I haven't really drove it but home so I don't know the history on the car....
My car is idling around 1100-1200 rpm's but when I disconnect the 3-wire connector from my icv, the car dies. I thought it was suppose to idle up higher than normal.
I checked the 3-wire plug, with the key on, with an volt meter and I am getting full voltage on the middle wire and half voltage on the one side but only 1.6volts on the other side. I checked the ohms on the icv itself and it seems fine (36 ohms on the middle and 18ohms on the outside pins)
I was thinking my old Mercedes jumped up when I disconnected its icv ??????
probably the accelerator pedal or the linkage assembly is binding/stuck...grab the throttle linkage in the engine compartment with the engine running and operate it manually...see if something doesn't change. You know, try to rev the engine by hand inside the engine compartment and see....could be nothing more than some WD-40 and a rag...
spray some eather in the intake and see if the idle returns to normal for a moment if so you have a vaccum leak somewhere if not then I'm stumped for now
... never heard of THAT method... easyer way is to take a can of carb cleaner and spray around all the vacuum lines(WITH the engine running) and around all the intake hoses if the RPMs rise you found your leak!
