Problem:
Car started having high idle(warm and cold) around 2,000-3,000. This started after no changes to the car, randomly. Diesels when turned off.
I took the vacuum line going to the idle diaphram off(the one that looks to have some sort of check valve on it, that leads directly into the diaphram), and the idle surged, and when i put it back on, the idle resumed to a normal position(1,000ishRPMs). I took the line off again and stuck my mouth on it and sucked in. The small amount of vacuum i created made the idle go down a little.
I thought i had fixed the problem, maybe it was just stuck somehow. The car continued to run with the correct idle for around half of one day. The car was started in cold weather, idled correctly and parked all day. When started for the 3rd(not second) time that day, the idle went back to the constant high idle.
I know the idle diaphram is screwing up somehow. What causes this? Can this diaphram stick, or is it a vacuum problem going to the diaphram? If so, where should i be lookingAll hoses appear to be fine, but i dont have a vacuum tester at school with me.
