Car fires without a problem, but idles quite rough, and runs very rich, so much so that when the it settles down to normal idles, it floods out. MPS was replaced with a used but tested one recently. When it was last running ( a year ago) it ran a little rich, but nothing like this.
As of now, the CHT is not connected. When it is connected, the RPMs jump up to 4000 and stay there. When the CHT is bypassed with direct grounding of the harness, the results are the same as with the sensor being disconnected. I have no reason to suspect the injectors, FPR, Decel Valve, or the MPS. Any and all advice is welcome. -Todd |

Did you check the adjustment on the FI Brain. I used to run mine 4-5 clicks from closed. CW to rich CCW to lean.

Thanks for the additional ideas guys, here is the status:
The throttle valve switch and intake mani gaskets are brand new. The FPS and the FI brain have not been touched since the car ran correctly, so we don't suspect them as being at fault. The TVS was removed and cleaned, and I will check the connections on the circuits when I can -- Which is more accurate for setting the throttle; matching to the picture, or setting with an ohm-meter? Also, does it make a difference if the MPS is properly bolted in? We have been leaving it loose/unsecured in the bay as we test things. Thanks again, -Todd |
