Does it idle good or bad. What happens when you give it gas?

 

Is there black smoke coming out of the tail pipe.

 

I suspect either you have a bad fuel pressure regulator, or the connection between the Ecu and the harness needs to be cleaned. Brake fluid works wonders there. Also hit the connection between the harness and AFM.
