To all you guy's who gave me suggestions, I want to say thanks! I finally got this girl ironed out. It ended up being two problems and timing wasn't one of them!

#1 was the ECM. The right side fuel injector driver was bad and according to Mitsubishi, sometimes when the driver craps it makes the injectors fire rich all the time. The ECM doesn't know this problem has occurred but it does sense a rich mixture and try's to lean it out. This results in the working bank running lean and the non-working bank running rich. Hence the retarded timing!
Note: This failure did not kick any codes because the ECM did not know it wasn't working correctly.

Swapped in a used ECM and the timing was corrected and she ran like a different motor.

#2 The fuel preesure regulator was faulty.
Once we got her timed right, she still didn't have as much pep as I thought it should. The fuel pressure was in spec but seeing how I had already purchased a new regulator I thought it couldn't hurt to replace it. BINGO, I don't know what was wrong with the original but once it was replaced she really came alive.

I tried a stall test but at 2000 RPM she spins the tires thru the brakes <img src="/forums/images/graemlins/evil.gif" alt="" />

I am tickled to have this ironed out. Everything seems to be working, she idles smooth, has a quick response and scoots right down the road.

The only thing I need now is a new EGR tube that goes from the intake to the exhaust. The one I have was broke at the flex, so I welded it back together but I don't know how long it will last. Any body got an extra one they would be willing to sell me or a suggestion of an alternative? <img src="/forums/images/graemlins/wink.gif" alt="" />

Well now I'm cleaning her up and checking the brakes (They ought to hold her for a stall test! Gonna replace the pads.) Then it's the ultimate test- 16 yr old driver! Go get em kid! <img src="/forums/images/graemlins/kewl.gif" alt="" />
