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???

Something tightened the valves up... That was probably stretched valves from running too hot~

Tight valves are a symptom.

Dont think it was tightening, as the engine never came half way up from the white area on the stock temp gauge. Think it was more of me not doing the valves properly.



to clarify:

no more white smoke out the pipe, just rich running and now i am trying to fine tune for optimal performance. I am certain that 29 degree mark is not giving this engine its full power.
