Finally got the car to start up last night and tonight, but will only stay running when the throttle is all the way open, but still only runs around a grand maybe. I have zero throttle response. I will not infect you guys with my thoughts and I will listen to what you guys think the problem could be. All the information would be greatfuly appreciated.

I am running 450 dsm injectors and I have the resistor box hooked up and done correctly. Got a 2.5 bar map sensor on there. If you wanna know anything else just ask and I will let you know.

And now the diagnoses are given.....

Thanks

full specs on engine also might help man. was this motor completely rebuilt fresh parts? etc...

what is your fuel pressure? It could be your FPR or fuel pump. And what about your timing?

I had that problem and my map sensor wasnt working. Fixed that and ran good. Does it run insanely rich?

1. Did you adjust the MAP sensor setting on the ecu to 2.5bar?
2. Did you set the fuel trim? running rich bogs it down since you have 450cc's
3. Did you by any chance **** around with the TPS? or accidently adjusted in a way?

I'm running a B16 with just new OEM bearings in it. The ECU was already setup for a 2.5 bar map sensor. Fuel pressure is right around 40. We screwed all around with the fuel pressure. Ran it way lay and high and still did the same thing. I popped in my stock ECU from my 92 hatch (P06) and it hit 2 grand and shut off. (I think that was just because it was not set for the 2.5 map). I was going to try and wire the stock map back in and try that.

Anymore thoughts?

Thanks for all that information. I will try each one and see what happens.

Any thoughts. I am going to change the injectors and switch back to stock map sensor since I will only be running seven pounds. Hopefully this will solve the problem.

The only thing I do not have hooked up is the electronic boost control. This would not cause this crappy crappy idle/ not driveable problem would it?

Jimster480

have you swapped it back to stock map yet?

Bwhit12

Not yet... I am waiting to get a new wire harness and then I will.
