Does this log look normal? And a long list of problems!

The car is a 90 tsi running stock boost with a aeromotive fpr, and a walbro 255. Its VTAing now since my rfl blew off my homemade recirculation pipe. I think thats the least of my worries right now.

First off:
The compression is between 90-95 across the board. Not good.

Second:
I launched it at about 5500rpms and now it makes a terrible vibration sound. Sounds like a broken engine or exhaust mount, but nothing seems to be moving more then before. I cant figure out whats going on. It sounds like an rc car/ baseball card in bike spokes/diesel (at low rpms). Any ideas with this would be greatly appreciated.

Third: Heres the log.
RPM: 5531
INJD: 58.5%
KNCK: 0
O2-R: 0.89v
TPS: 96.4%
TIMA: 15degrees
02-F: 2.50v

RPM: 1406
INJD: 4.6%
KNCK: 0
O2-R: 0.91v
TPS: 33.2%
TIMA: -5degrees
O2-F: 2.50v

RPM: 3062
INJD: 18.7%
KNCK: 3
O2-R: 0.82v
TPS: 97.6%
TIMA: 15degrees
O2-F: 2.50v

The O2 sensor is pegged at 2.50v through the whole driving cycle. If im not mistaken, then that means its running extremely rich right?

3 is the highest knock count throughout.

thanks for all your help?

That compression is terrible, it's time for a rebuild... once your engine is healthy again, then it's time to post logs.

I agree with blingstatus. unless your living at over 10,000 feet your compression is bad

HAHA you funnay; but anyway yeah you can't really do anything unless you rebuild your fire engine.

looks like its time for a 2.3l stroker kit.

is there any cheaper way to go about it then slowboy?

Go to www.jackstransmissions.com and send him an email. He was having a sale on a stroker motor. Not sure if he still ships motors due to liability issues but he still may do it.

Just noticed your from denver, send him an email and he will give you an awesome deal on a motor.

With the program you are using, O2-F is nothing. O2-R is actually the front O2 sensor, so that's the one you want to look at.

hmm... Thats odd. So its actually running slighly lean?
