Hey guys

First off, im sorry for starting yet another thread on the topic, but i feel bad hijacking another persons thread, taking it into different direction and them not receiving help they are waiting for.

I did the stomp test on my 535i 89, the check engine light did what it was supposed to do, and i received the 1444 - no fault code. However my idle varies slightly in the cold start then stabilises itself after few seconds of varying. I thought after i got the check engine light to work id finally get the code and see whats wrong with the varying idle. Now with "no fault" im back to square one. Not a major problem (ive had lot worse) but it bugs me .

Anyone have any suggestions?
