LOPE

KC
I have replaced everything under the hood, I dont know what to tell you mine still lopes slash surge I dont know what you would call it. I call it 3k later and sanity is leaving day by day. The men in little white suits will be here soon. I have reduced the lope a little by putting new injectors, I have not replaced cross over tubes yet but after going this far whats 125.00. Its all new under the hood changed out 3 vp's and all of them do the same. My last vp is a blue chip.If you go to you tube and type in JL Welding truck you can here what mine is doing. It also has a erratic miss. Running A/C and it is a lot worse.

FOUND IT


Scaned again for the 20th time and found it. Ecm is receiving 13.65 volts going into. Coming out and suppling vp 11.49 Unless someone here can tell me that's normal. My thought is there should be at least 12volt or higher.
 
Looks as if something in yoru ECM is sinking too much current to me. May try finding a buddy with the same truck and swaping for a test drive, no longer than it takes to swap an ECM. Should be able to do it in around 15 minutes. I've done that a couple time to rule out the ECM.
 
Yes sir I swaped out actually bought a ecm from Brandon on here and it ran the same. It has to be a connector pin or near break in my harness I think. It will be in shop at Austin Fuel Inj. first of next week.
Justin and Billy where more than helpful there I felt like I knew them for a long time, truelly good people. They went out of there way to help. When it came time to pay for the four hours of labor they told me dont worrie about it.
 
Man I watched video and that is exaclty what mine is doing. Did you end up getting a new harness, ecm or fix bad connection?
