My truck is smoking HELP!!

[dixonbgood]

I have an '03 F250 w/ a 6.0. I have a 4 inch turbo back exhaust, banks intake and Edge Juice w/attitude. I usually keep the edge juice on the mileage setting, i drive 67 mile to work and 67 miles home. The other day i filled up in the morning and went to work. On my way home my truck started smoking. Not bellowing smoke but still constantly smoking. the color is black. When i got home I let it cool down and then shut off the truck. Started her up again a little while later and she started to idle real rough, kind of loping in surges and black smoke out the exhaust while parked. The check engine light has not popped on at all. The first thing that i did was pull the edge juice off and put it back to stock. No luck, so i pulled the egr valve and cleaned it really well. No luck, next I drained the fuel water separator and no changes. I checked all my plugs and vacuum lines and all is good but i still cant find a solution to the problem. Any ideas, im lost and need help.

Check for codes....they don't always trip the CEL.

Im gonna give that a try. Im just afraid to drive it for fear of a ticket for the amount of smoke im putting out.

Looks like you live close to Diesel Tech, give Loren a call.

I scanned my truck and the code p0403--Exhaust gas recirculation circuit malfunction. Any ideas on what to do?

[POWERSTROKEMIKE]

i would call loren at diesel tech he's close to you.. to me sounds like a inj failed

[SteveBricks]

Could be, but I'd suspect the EGR valve first....probably isn't closing completely.

Someone (like Loren) with the proper computer software could diagnose it easily...a function test for the valve, contribution test the injectors, etc...

Called diesel tech. Gonna take it down tomorrow morning. Maybe now i have an excuse to tell the wife i need head studs and other goodies. Will keep yall posted and thanks for all the input.

[POWERSTROKEMIKE]

What turned out to be the problem? When you ask these questions, you have to provide info so we all learn. Not being mean, just asking. Thanks.
