Car running, runs like 4 cylinder diesal

[E30godz]

i was running around with the car with about 3 feet of exhaust on it and it ran like shit...stupid slow and puttering, and i attributed that to the fact that there was no exhaust on it. Now i have exhaust on it and it runs the same.

the idle is fairly steady and it will rev the 6500 but it goes like a 4 cylinder diesal....it takes forever, its heavily down on power. Keeping up with traffic is kinda difficult....sooo im not sure whats wrong? All the cylinders seem to be firing as i took off each wire to each cylinder while it was running and the engine started stumbling noticably each time.

it also has a small vacuum leak on the AFM boot, but its been there and its never run this ....slow before.


poor acceleration.

I had a hole in the 90 degree rubber boot that connects to the AFM, my car ran like shit because of it. I got some plastic posy stuff to seal it and it runs much better. I was so amazed a small slit in the rubber can make it run so poor. Get a tube of that plastic filler stuff, and fill the leak, my guess it will really make a difference. I guess the engine really needs to be tight where the flow of air comes from.

i dunno...ive sealed it up with dut tape and ive had worse vacuum leaks...this drop in power is phenominal...its like driving a 318i
