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.
