Hello, does anyone know of a way to test my engine loom an on m42 e30 318is.
I need to test the ICV connector/loom part as i have a feeling the ICV is doing nothing at all. I've tried two known working ICVs, they both have the same malfunctioning/not working effects.
Also, i need to test the TPS wiring. If i tug slightly on the connector, the engine will stall...which is a bit weird.
The loom and connectors are a bit worse for wear after the engine was shipped on a pallet and transported around.
Help is much appreciated.
Thank you.
Testing the loom

This will give you the wiring diagram: http://www.autolib.diakom.ru/CAR/BMW/19 ... 0DIAGRAMS/
Then it's just a matter of checking each wire with a continuity tester.

Do my symptoms sound like the icv is not working at all, or isn't being allowed to work?

Hello again,
The symptoms summed up more concisely:
If it disconnect both the ICV and TPS, the engine runs no different as it does to when they are both connected. Is it possible that the wiring may be at fault here?
Also, i can't hear the ICV buzzing when in key position 2
The MAIN sympton however, is that the car idles at 500 when cold, and 1200 when warmed up. The idle rises as the operating temp of the engine rises.
As well as this, i feel this problem may also be related:
When clutch is depressed slightly when in gear, the engine revs drop down, and will not rise whilst the clutch remains depressed. As soon as i press the clutch down, the idle rises back up to a steady value.
Thank you.
