For the last several years i have been driving a 928 s turbocharged with a T04 and an electromotive tec III, 45# injectors etc etc. I have gotten very spoiled with the tec III because it is so easy to diagnose and it is pretty much bullit proof.

At any rate I was ready for something differnet so I found a 103K mile well maintained sweet 87 944 turbo in really good shape. My friends cant even believe its 18 YO. It had around 13G worth of work done in late 2002 and sat for 2 years. At any rate...........


Problem #1
It starts up a little rough, hot or cold. I rev it a couple of times and withing 20-30 seconds its very smooth. No idea whats causing this since it does it all the time.

Problem #2
At 4000rpm and full boost it starts breaking up and acts like tis not getting enough fuel. The guy I bought it from bought it not running from the guy who spent 13G in 2002. I asked what was wrong with it when he bought it and he said the fuel pump, but who knows. First off I plan to change the fuel filter, because I could not find any info on when that was done and also check that it is really a turbo fuel pump.

I also though that this could be the knock sensor false alarming.

Any ideas ??
