just returned from another carriage delivery and was surprised while making my deliveries to see my carriages covered with a diesel soot dust on them. Have been delivering them for a couple years and this is the first time expeirencing this?
Mileage is about the same as always and is running great. I did add a stainless steel extention on my exhaust pipe that prevents the soot from getting on the truck but would not expect this could cause it ??

 

You didn't add the injectors and edge recently did you?

Wouldn't the IAT sensor be the first to look at? I did notice the automatic trans / no jake... But it sounds like it.

 

the injectors and rdge have been onboard for quite a while. run's as good as ever. the only recent change was the tail pipe extetion

 

It may be in the fuel. Try some conditioner and a different brand of fuel. Also check your air filter.

 

Could be the new extention is pushing the exhaust into a different part of the airflow around the vehicle and the turbulance is directing it to a new area.

 

Just a thought. If the only thing you did recently was add the extension, then I would look at that to be the cause. It might have put the exhaust in just the right spot to hit some turbulance that the exhaust stream wasn't in before.

 

mkubacak can type faster than me.

 

Aim the pipe straight out the back, the extra propulsion will make your truck go faster.
At least that's what the Ford guys tell me.

 

go faster??? i am wearing the brakes out trying to slow er down

 

Hmm... maybe your scorching them you're going so fast.

 

Maybe it's not soot yer seeing but brake dust

 

So you're telling me that my exhaust when it was straight back was the real problem and not the chrome propellor I had on my hitch receiver?

 

Yes.
