Need help 6.0
Hi Everybody,
This is my first post. I have a 04 F-350 Lariat crew cab long bed, FX4, 6.0 automatic. The only modifications are K&N filter and straight pipe. Truck has 111598 miles on it with out a major problem. Had one sensor changed @ low mileage on warranty. 3 month ago had 2 days when truck was bogging down & belching black smoke, cleared up on its own. 2 weeks ago batteries were getting weak, installed new, shortly after began to start hard & run rough for first 20 miles or so. Now truck will only start with use of block heater. When accelerated past 1000 RPM engine starts surging to 1500 RPM to 500RPM about 1 second intervals while belching black smoke. Had diesel shop check readings,no codes and injectors showed good, with slightly low voltage. Have changed fuel filters,added fresh fuel with Lucas Fuel Treatment.Checked and cleaned EGR,only had light coat of soot. Changed EBP sensor and checked tube from exhaust manifold. Disconnected EGR, no difference. disconnected ICP sensor, no difference. Was getting ready to sell truck as I do not need heavy truck at this time. Plan to get smaller Ford at this time.Any advice on this problem would be appreciated. I would make anyone a good deal on this truck right now ! Other than current problem truck is in excellent condition. $15000
