Yet another nagging issue with my truck....I'm still getting a gnarley hesitation under load and it burns your eyes to stand near the tail pipe its running so rich and after testing and replacing everything and I mean EVERYTHING on this thing except for the paint job, I've noticed the resistor for the coil is completely frapped. When i look on the FSM it shows the resitor and condenser being one unit but with mine thats not the case, they're seperate. With this, the only one I can find new is in Saskatchewan and the shipping costs as much as the part itself (which isnt cheap). The parts prick (he was a real dink so pardom my french)at the dealer even asked "is it the brown one or the black one?" i replied it was the brown and all I received in return was an "oooooohhh ouch, the brown one". Anywho, would it be recommended i buy the exact one or could I use a combined unit out of a different year? And/or would this cause my problems?

I'm completely stumped everyone so I apologize for yet another answer hunt.

Sorry, I don't know about that, but I have to ask...

 

Have you checked/replaced the temperature sensor for the ECU? I understand this can effect fuel ratio considerably...

I have, I've just swapped the ECM as well but to no avail. I'm not getting any codes and It's become a serious bug hunt. It's running very very rich and the fuel i'm going through is intense. Not to mention it bogs out badly under load intermittently. The only thing I'm going to try now is to order this resistor and hopefully it changes the issue. I noticed in the dist. cap (being brand new) the contacts are already getting buggered up. Could this be because there's 12 V running to the coil even at an idle therefore creating too much heat?

You sure your injectors aren't leaking or your fuel pressure isn't too high?

Fuel pressure is perfect, ran around for a day with the tester zap strapped to the wiper. It doesnt even drop when its bogging out
