Lose of Power (real hard)
My truck is loosing lots of power. I can not go speed up, but the truck is drinking fuel (11.8mpg instead of 20mpg before).
I changed refill full the gas tank twice(thinking in a bad fuel), but i still have the problem.
when i try to acelerate slowly, truck does good. i can reach 60mph acelerating slowly, buy if i push hard the pedal, the truck does not reach the final speed, it seem something is pulling backwards.
i try in manual position, when im in first and push hard same happens, it goes very slowly to the final velocity.
there is no light that says engine check.
Brakes seems ok, no hot weels or something, all liquid levels ok, air filter clean, no hot engine. I went to a shop and they changed all the spark plugs, but nothing happen.
Today in another shop, the guy told me that maybe is a damage fuel pump, or the inyectors are soo dirty and needs to be cleaned. I dont know what to do at this point, i think it is safe to drive like this because no engine check lignt.
just 10 days ago i fuel the tank in a gas station quite suspicious, maybe that fuel was dirty or maybe that was not premium fuel, i dont know what to do now. If somebody can give me a suggestion please believe me it helps.
If nothing happen to the end of the year, im planning to go to the dealer (probably they will told me to change the hole engine, all suspension, even the tires for thousands of dollars, they are good doing that).
The truck has 70,000km. 2008. Im looking after my warranty info, but probably the dealer will say that i didnt change the windshield water with them so the warranty is avoided (this happens in Peru with Jeep, incredible!!)
PLEASE ANY HELP IS WELCOME
