Any Tech Help Please-Engine hiccup, skipping
Have some trouble with my 2004 F-350 6.0 L it has 115K miles, I’ve owned it the entire time.
Problem had been going on about 2 months, when the truck has been sitting about 4 hrs (going to lunch, after work) the engine skips and sputter, hiccups, bucks & chokes, what ever you want to call it. It does not put out smoke, only if you really get on it, then it puts out grey smoke. When it skips it also has a lose of power,
It got really bad last week and we took the EGR valve out and cleaned it, it was really clogged up. Truck runs a lot better, BUT now it skips a little bit all the time.
I do know that the EGR Cooler is cracked, happened back in February, and we put 2 bottles of Bar’s Leak and it has not leaked more than 1” per week out of the degass bottle, and then only if I take a couple hour trip, then it leaks only that night.
I have run Lucas fuel cleaner thru 3 tanks, 1 tank with kerosene, 2 tanks with Sea Foam, and have changed both fuel filters. We have also had the truck running with the computer hooked up with no codes coming up.
The skipping never gets bad enough to stop the truck, just have tried everything I’ve been able to think of if it’s dirty fuel.
It is a stock truck except it has a Hyper tech computer chip.
I know it’s impossible to diagnose with just my limited info, but any suggestions of what to look for would be greatly appreciated.
Thanks again for any input, let me know if you need more information.
