Looking for a mechanic

[1987E30project]

I need some recommendations for a mechanic experienced in repairing E30s in the Beaverton Oregon area. My car has the "erratic idle disease" and I have been unable to find the cause of it.
It all started after I changed the timing belt and tensioner. I also changed spark plugs, wires, rotor, oxygen sensor, fan clutch, adjusted the valves, new motor mounts, shocks, springs etc, etc, aaaagghhhh.:crazy:
Yes I have been using the Bentley manual. If the timing belt was off by a tooth would that cause the surging? Any ideas before I pay a mechanic. It did not have this problem before I changed all the parts.

Anyone??

What are the problems you are having? try and make them detailed as possible.

Possible that the plugs are not gapped correctly or that the timing is off because the cap was installed incorrectly? Just some ideas to get the ball rolling here.

i was thinking the timing was off.

Pedro,

The symptoms so far are. Idle OK while cold. Then it revs from 200 to 1200 rpms once warm. I thought it was the oxygen sensor but I just installed a new one two days ago. I tested the ICV and the resistance is OK and it closes if you apply 12v directly. Put some cleaner in it and checked the hoses attached to it. Everything checks out.


Mike325,

I gapped the plugs to the Bentley specs same with the cap.

Being that the problem started after the timing belt replacement I was thinking that it would be something related to it. Also the "check" light has been flashing since I bought it.

Is there a way to check the timing now that it is all assembled.

throttle position sensor
vacuum leak

is the check light just for the brake lights?
