Ive been reading this because some of the authors poroblems are the same as mine. Ive recieved many suggestions that add up to SO MANY things to check or replace that my head is spinning. My truck idles at about 750. It Never EVER idles faster than that regardless of outside temperature. Sometimes, but not always, I get a lot of white whispy smoke from the exhaust. All the time though lately, the regular exhaust smells a bit different, almost like something burning. Until Ive idled for at least 5 minutes, it will not respond to throttle and acts like my bumper is up againt 10 tons of weight. This is in any temp under 50 or so degrees. All last week it acted TERRIBLE w hard start, engine jumping so hard I thought mounts would brake, then after a while acting like one cyl was dead. Idled pretty well but went crazy unbalanced when trying to increase rpms. Tank was about 1/8 full. Yesterday I went to station and brought back 10 gals of new fuel, also adding diesel additive--I think 'dieselpower'? Started hard but after a minute purred like a kitty! Drives well now except I hear a light knocking like at certain rpm , usually not under load such as coasting to a stop. It reminds me of wrist pin problems I had in an old chevy 350. Im having a little fuel in the valley on top the engine but cant isolate the source. Also I noticed that once in a while when turning the key to the position to heat up the plugs, I heard almost nothing as opposed to the usual clicking buzzing etc. This thing is driving me nuts. Someone suggested its because I keep the thing at 1/4 tank or lower at all times and its not picking up fuel well or sucking crud, etc. Other have mentioned the injectors, relays of all types, sensors of all types, rail pump?? Fuel line at pumpsucking air, etc etc I cant afford to take it to adealer but it sounds like ifI try to start replacing all potential problems Ill spend more in long run and have the truck down for weeks. What a love/hate relationship these things are...
