???Fuel Pressure Regulator???
I've acquired a skip or surge. Under throttle the truck runs good. Does not over heat. No coolant in the crankcase. No fuel in the crankcase. No smoke other than black out the pipe. Runs and idles fine while reaching operating temperature. Once it gets to approximately 190/200 degrees it starts a random surge in neutral or in gear. Seems to be worse in gear. The fuel filter (wix) has 100 miles on it. I'm currently running a mixture of hotshot extreme FUEL additive to see if it might be a clogged injector. Mixture is proportioned for 12 gallons to see if that would clear it up. Does anyone have an opinion or experienced these symptoms. I haven't checked fuel rail pressure. These symptoms are present weather tuned or not. Running a super chips have tried ALL settings and now running stock. I have already replaced the #2 &7 pigtails previously. I'm thinking fuel pressure regulator?
