Rough Running + High Fuel Consumption = FPR??

[tcyoung2]

I have an 89 325is in which I just replaced the head. I've put about 150 miles on her since her reassemble. Problems:
1. Runs rough - seems to stumble through acceleration
2. Won't rev past 4000k. At several points while driving her, she wouldn't rev past 3-4k. At one point she didn't even rev past 1500 and I had to pull over. Once I let he rest for a few seconds she was okay.
3. High fuel consumption - I burned nearly a full tank of gas to go 150 miles.
4. Started her up yesterday and had some smoke coming out of the exhaust. After about 15-20 seconds it stopped and normal exhaust was emitted. I also noticed a slight amount of exhaust exiting around the number 6 cylinder exhaust port.

I initially believed that it could be a problem in the ignition system. Results from my check:
Coil:
Primary Resistance: 0.8ohms
Secondary Resistance: 5910 ohms
Wires: (checked from their corresponding contact inside the cap to their end which connects to the spark plug)
6070, 6160, 6030, 5850, 6060, 6120 ohms
Coil wire: 1990 ohms
Rotor button: 1270 ohms

According to the bentley, the coil and the wires may need to be replaced. I doubt that they are worn out enough to cause such a problem with the car though.

Let me know your thoughts and suggestions. Thanks!

Check the rail fuel pressure and pull the top timing cover of and check cam timing.

What color smoke was coming out of the exhaust? I'm with Jim on double checking cam timing, sounds like it may be a tooth off.

+1 for cam timing.

also: your car is a machine. it does not have a fucking gender.

Unless you child names your car; then you just go with it. :roll:
