Cleaning E36 ICV (Idle Control Valve) . . . DIY! http://www.bmwe36blog.com/2007/06/23/cleaning-e... Hi Guys,Car hesitation and RPM bouncing are the most common problems between the BMW E36 cars. It seems that many cars have the problem and the problem is very hard to fix. I recall that even my previous E30 used to have the problem, but some how, the problem was solved. Maybe with something that I did and didn t notice it fixed the problem.
