blacksmoke/soot at idle, undriveable

I have an 89 with the Chrysler 2.5 liter Turbo. I have never looked at the compression, the valve assembly, or iginition timing though. Ill ask my friend tommorow to do these things and get back with you. He is currently working with me on a real BEAR of a problem. Ill show you the post I have on Technical/Engineering Thread. Unfortunetley I have had NO responces to help me at all. This stupid thing hasnt ran good enough to drive for like 7 months now, and it still doesnt run... hmmm maybee tomorow...My post is as follows:
=========================
1989 chrysler 2.5 liter turbo with 4 port fuel injection.
engine idles poorly w/ black smoke, runs fine at or above 2500 rpm.
will not get higher than approx. 3500 rpm, stalls at that point when put into drive. In addition when more pedal is applied at 3500 rpm the engine bogs down like its too lean.
Replaced:
1. MAP sensor
2. throttle position sensor
3. oygen sensor
4. disconnected the EGR Valve
5. checked distributor and plugs (did not check timing)
6. replaced fuel pressure regulator
7. checked for blockage of airway
8. replaced main computer
9. checked for the feel of vacuume from various hoses, but did not take redings.
10. did not do a compression check.
If anyone can help, please email at [email protected]
Im desperate now as my backup vehicle is on the way out.
Thanx Rodeee... the bald guy with the speckled mutt.
