Rough idle on 89 525 when first started

[jterrell]

Has anyone experienced the problem of their 525i running rough for the first few minutes after starting? This problem corrects itself after about 1/4 mile of driving but it is annoying and we want to try to fix it ourselves.
Any advice?

Hi I own a 525i also. Recently i replaced some crankase hoses that connect to the intake manifold and fixed my rouhg idle problems. A good close inspection of hoses going to and from your intake might reveal some leaks which cause the rough idle.
