Cold weather issues
I never knew about this issue coz I never drove my 1990 E30 in the snow. But the other night, I decided to take it out on the road, after it had rained. Ambient temp was about 40-45 degrees F out, and as I got it out onto the road, for some reason it didnt make power til i got it past 3500 rpms, which was a chore. It only did it that one time, after that it was fine. Engine is M20b25. What would cause this issue? Id like to know. It was almost as if it was out of gas, but it had some gas in it at that time. I also notice that if I start it when its cold out, and I go to rev the engine, it dies. It DOES NOT have a cold start injector. It is after the cold start injector had been phased out of the E30s.
