I have a 1989 325ix that had recently had an intake mainfold gasket replacement. The vacuum leak allowed the system to have more air then usual and after being fix it now has a cold hard start problem. Because this model uses a the Motronic system, there is no cold start injection module rather, it uses the computer to engage the system. I once heard that there is a possibility that there may be an injector stuck open that may be slowly flooding the engine. However, when I had the fuel rail off to change the intake gaskets, there wasn't a problem with them. Plus, when I pump the gas while it tries to start, it helps it out and it starts a little sooner. If anyone has had this similar problem with an E30 325 model between 1988 and 1990, please post here. I am interested in solving the problem with out too much cost.
