I was getting around 19-20mpg in my truck I recently had 4 objectors replaced now it gets around 11mpg and smells like raw diesel at idle. It has great power now but it is terrible on mpg. Is there a way to regulate fuel going to the objectors? Or is there maybe another issue?

 

Sounds like you're leaking fuel on top of the engine somewhere. Check the valley to see if there is a puddle of diesel on top of the engine.

 

I have not noticed any raw fuel on the engine...

 

Where did you get the injectors from

 

Bean diesel I think... It was from Nashville Tn

 

You may have got a couple bad injectors that are leaking to much fuel into the cylinder

 

Also blows white smoke at idle. Smoke smells like diesel fuel as well. It done this before the injectors install I was told the newinjectors and glow plugs would solve this however the only thing the injector swap has done is give it more power and half the fuel economy.

 

White smoke is unburnt fuel. Does it go away after the truck warms up?

 

Lightensbut does not go away. It is only noticeable at idle. Driving down the road it is not noticeable.

 

Did you or someone else install the injectors?

Make sure the MAP sensor hose is connected, easy to forget after installing injectors ...



Make sure hose is not clogged, especially at engine intake side. Have you tried unplugging the MAP electrical connection to verify MAP is working properly? You will need to take it for a spin and you will get a CEL light but it will go away when you plug it back in. If things run much better then sensor or hose is defective.

Any chance you have or can borrow a scanner to watch real time data, that would help isolate things quickly.

 

Ford mechanic installed... Forgive the ignorance but... Map sensor??? You said unplug take for a spin if it runs better replace? No I do not have a scanner or know anyone with a scanner that I could borrow... Again forgive the ignorance but by trade I am collision repair and paint not very mechanically incline.

 

Where do you live maybe someone here is by you and could scan it for you also post in your state chapter section to see if someone could scan it

 

Jackson, TN

 

Yes the MAP sensor is over your AC blower it had a 3 wire plug and a hose going to it. Unplug the electrical connection take it for a ride and if it run better then the sensor is bad

 

Ok I unplugged the map sensor a lot better but in replacing the clutch slave I found a fuel leak.... Coming from around the starter and trans any help...
