BMW E36 Forum

I am having trouble with my 318is it does not idle, have turned to idle up so i can drive it, some days it will drive fine most days not so good lacks power idle rough hard shifting i have sprayed 2 tins of carby cleaner around to inlet to find leaks but nothing and then when i took the manifold off the inside had a silver liquid almost like it was painter silver on the inside i have put even had, I have had the problem of the air vents over flowing with water into my computer compartment but been checked and they reckon no codes its all good but is still dont run right. the computer has E34 written on it is it the wrong computer??? i have been told many of things it could be

hi
with this silver liquid was it everywhere and did you clean it before you replaced the manifold???? oh and btw how hard was it to take off as i have a 1992 m42 engined 318is and was gonna have a little fiddle and/clean out?
