Am I reading this right? You're swapping out a big 6 and putting in a 4-cyl? What car is each drivetrain coming out of and going into?

Not judging, just wondering...

I'm suspicious of the AFM now--I checked it out and the cover appears to have been taken off by a previous owner so it's been part of someone else's troubleshooting.

I don't want to loosen or adjust anything that I should be avoiding; can I reposition the arm to be outside of the worn "track"? Is ...

I've been doing research to see if anyone else has had the same problem to see how they fixed it... I've found someone who had a situation that sounds identical posted on Roadfly a few years ago, but unfortunately the only response they got was "Go to First Fives site instead."

Forgot to mention, I have also recently replaced the out-of-tank fuel pump, fuel filter, and fuel lines running between those parts and the tank.

My '81 528i has developed a particular sputter that I've never experienced before. It's an E12 so it has a rough idle--hasn't been a problem yet. It has also had a whistling sound for the past month or so; the sound comes from somewhere around the front of the engine and disappears under ...

E21 Recaros are a straight bolt on.
I also found that early and late E12 seats are intergeable. You just have the use the rails that go with the car.

Not true in my experience-- I've made some ghetto brackets to adapt some E21 Recaros to my E12. I've been wondering if there are other OE rails ...
