used Hi, this is my first post! Lucky I have a problem, or I might never have found this site!
I am a fairly competent BMW wrench guy, having owned three other cars. I have changed drive shafts, replaced timing belts, and other routine maintenace proceedures, but this one is very puzzling.
Last night, I went for a late drive. I live in Ohio, and it was very cold, about
7 degrees. (or so said the on board computer). The car stated instantly, and would idle, but any attempt to rev the engine, resulted in stalling. After allowing it to warm up to full operating temp, same thing! I can drive it, but it will not tach past 2k! Has almost no power. It was fine when I drove home yesterday and the car has been recently been tuned. (new plugs and wires) Too damn cold to play around under the hood, I suspect a stuck cold-start valve, or maybe a stuck
air flow sensor. Any thoughts would be appreciated!
