New To Site, Have Some Questions

[Dj_325]

Hey whats up everyone. Im brand new to this site. My name is DJ i live in Kentucky and im 16. I recently bought a 1986 325 BMW. Its not only my project car but my soon to be daily driver.

My questions are pretty simple, hopefully someone can help me.

1. The engine in my Bimmer idles really erratic. It revs really high and then really low and then back relaly high. It only does this some of the time though. What can it be?

2. I also have a 85 528E. Not exactly the same car, but the 528 has no tranny, but the engine is in good condition. Can i swap a cam in my 528 to my 325 *The 325 has a flat spot on one of the cams*

More questions to come im sure, but for now i appreciate any help. Later

its the same engine so the cam would be interchangable.. but if there literally is a flat spot on the cam lobe, that would indicate a oiling problem, one that i would get looked at NOW...

and the eta engine has a idle control valve.. check it, clean her out, and presto idle hopefully is fixed.. otherwise you may have a vaccuum leak.

this is a question and an idea

if the cam lobe itself has a flat spot, maybe that can throw off the idle since maybe it throws off the intake/exhaust/ignition or compression?

just an idea. . .

Quite possibly could be the Cam. I think i will try to replace the Cam as best as i can this weekend and see how that turns out. Where is the ETA on the idle regulator located?
