D-Jet WAAAAY To Rich, or JOES 2012 HERSHEY EMERGENCY THREAD Options

[jsayre914]

My 2056 w/ D-jet has almost 200 miles on it, i have been tweaking little things here and there. Today I was trying to adjust the TPS. I turned the ignition on and slowly opened the throtle till i heard 20 clicks and then i tightened it down. Got on the freeway and seemed to run a bit better (less bucking) but then i drive 30 min and starts jerking like crazy

I am loosing at least 1 cylinder under steady cruise and pick it back up on accleration. I get to the end of the freeway and i cant even idle, feels like running on 3 but still has full power. I also hear a knocking sound.

shut it down. put the tps back where it was, pulled the plugs. BLACKer than black. Wipe them off and start it back up. Engine is idling rough and i smell gasoline strong from the exhaust.

I pulled the wire off the head temp sensor and grounded the lead to the negative side of the battery, and I think it helped. I also adjusted the idle screw and the knob on the ecu till it seemed like it smelled less like gasoline.

Here I am, firing on all 3 with full power, engine pulls strong but a lot of misfiring due to rich fuel i believe


what the hell is going on here???

Joe, I went back and read your build thread looking for clues. Rwilner asked but you did not answer re: which CHT sender? is it compatible w/ the ECU. Also, the MPS; is it compatible. Does the MPS also ohm out correctly. Did you ever dissconnect the TPS to check driveability? I noticed that your injectors were rebuilt then rebuilt again after setting awhile. These are suspicious to me. Have you rechecked your valve clearances. You didn't clamp the air cleaner down over the fuel return line did you? You also mentioned that it idled great when cold and stalled once warmed. Did you ever correct that? If your MPS, ECU and CHT sender are kosher and working and if your running the 9550 cam; roll your idle controll CC all the way. You'll never get it tuned to idle, otherwise. One more thing; did you verify that the mark on the dist is at the correct position? Hang in there. (IMG:style_emoticons/default/beerchug.gif)

EDIT: Can you post a pic showing your dist from the top view w or w/o the cap on it.
