Strange idle - transmission related problem
I got a 1994 325i with auto tranny; about 110Kmiles.
Here is the challenge:
if transmission is in "D", and I come to a stop, the idle keeps popping/moving between about 4-500rpm all the way up to 900-1000rpm up and down.
If I have it in "3" gear, it is rock steady at about 700rpm.
So, I started checking into this, and here is what is so strange:
if in "D", and I barely touch the shift lever and push it ever so gently towards the "3" gear, it immediately goes steady to 700rpm; if I let go, it starts jumping again.
So, can somebody please explain how this can be (i.e. relationship of gear and idle); and more importantly, how do I fix this?
Is there an easy way to "adjust" that shift lever???
Appreciate your help!
