Bogging, Smoke, CEL, HELP!!!
02 f350 7.3 289K auto. 5" Exhaust, K&N filter, HPOP Crossover, Gauges, No chip or programmer as of right now. Getting ready to order a PHP.
Running Howes Diesel Treat.
It's been 20-40 degrees in the morning lately. I keep my truck plugged in all the time. When I start it up in the morning it seems to take longer to start than usual but starts right up and runs fine. I let it warm up for 10-15 minutes then head to work. When driving it will load up start to bog and blow white smoke. It doesn't do it all the time and it only seems to do it when I start to lug the engine. When it starts to bog and smoke it will throw a check engine light and start running rough but then will clear up the light goes away and it will run fine for awhile.
I had a check engine light after it happened yesterday so I pulled into O'reilly auto parts and tried to run the codes but it didn't have any codes.
I've searched all over the forums and haven't seen any post with the same problem.
I am going to try a fuel filter and oil change tonight and see if that helps. Don't think the oil has alot to do with it but it's due anyway.
It started about 3 weeks ago but would only do it one time after I took off in the morning so I figured it was just cold but now it's doing it all the time after my temp is up and my egt's are around 700.
Egt's are fine when this happens, The truck is still putting up 21-23 psi.
Fuel mileage has dropped from 12.7 around town to 7.5 on the display. I know that's not completely accurate but the truck is burning a ton more fuel.
If anyone has any idea's please help! If I can't figure it out soon I'm going to have to take it to the shop and have them diagnose it. It's only $65 but it takes them a couple days and I need the truck.
Thanks in advance for you help, Derek
