Well fellas I need some help. I have noticed a power loss on my 96 dodge 12v. Im not really sure whats going on with it.. I have had the truck for about a year and a half and can tell its not as strong as it was when I fist bought it. Its got 135,000 miles on it. I pull a 26' gooseneck steel horse trailer. With just the truck alone my mileage went from 17 to 15 since ive had the truck and noticeable power loss. Any suggestions on what is going on.. All help is appreciated...

 

cheek your air filter and fuel filters to start with.

 

sounds like filters to me

 

Also might wanna check fuel pressure. I've been having the same troubles myself as far as loosing power and fuel mileage, i need to change my FF. Also I've heard during winter time all vehicles loose fuel mileage because of extra oxygen in the fuel. I've always been taught, Winter for horsepower and summer for fuel mileage! Hope this helps!

 

The fuel filter is brand new, and as far as the air filter it looks good... I put a BHF on it with the filter from fleetfilter. How hard is it to chek the fuel pressure?

 

Try a tune up on the truck if thats not it, then id say it's the tranny! Same problem in mine! 47re= Garbage!

 

What kinda suggestions do you have for a tuneup..

 

an all around tune up, Looks for leaks, tranny, and makes sure the pressure is right in everything. Epecially fuel pressure. Like i said on the phone man, i think your looking at a tranny problem because mine is going down hill the same way. Let me see what my mechanic says about my problems and ill let you know whats going on wednesday!! Give me a number to reach you afterwards and i betcha were having the same problem!

 

Anybody else got any input?????

 

I know I sound like a broken record but check the pre-filter in the fuel heater. That burns a lot of dudes.

Have you seen a drop in boost or an increase in EGTs? Anything?
