Low Power, Fuel Mileage Drop - Help Please
I have a 92 Dodge D250 with no modifications other than an Air Dog Fuel Pump and all of a sudden I have no power and fuel mileage went from 19-20 miles to the gallon to 8 miles to the gallon.....I have to put the pedal to the floor just to get up a slight incline. Does this sound like a Turbocharger? Not sure what would effect me so dramatically like this..
If it is a Turbo and I need to change, any recommendations for replacement? Can I troubleshoot myself? :humm: |
What's the engine doing (or not, as the case may be) when it is floored going up a slight incline? Miss, sputtering? Smoke? What color? Unusual noises or smells?
Gonna need alot more information to figure this out... |

check your air filter
|
So it's getting plenty of fuel, but not enough air - major boost leak? Torn intercooler connector?
Don't push it too hard like that - EGT will be through the roof. |

Have you actually inspected the turbo itself yet? |
EGT=exhaust gas temperature, I agree on a possible boost leak. Look all the rubber boots over real good and check to make sure none look as if they have moved on the piping I"ve seen the clamps fail. If there are no obvious leaks do an either check. Why do you suspect the turbo, is it making extra noise or some squealing sound which could also be a boost leak? Most turbo failures on stockish engines are oil leaks and not complete turbo failure. :rocking:Rocky

i agree with them it has to be a boost leak the stock boots tend to dry and split

Checked all of the boots (at Turbo, both sides of Radiator and at the intake). Basically my theory that the turbo might be bad seemed to be false so I have no idea what to check next. |
