2014 isx vibration

[race7820000]

ok..........so the chatter under a load is completly gone. the clutch is nice and smooth now and there is almost no vibration from trans.

but when you pull under a load the motor sounds like crap and the truck shakes, u can fell it in the steering wheel and the dash, as soon as u back off throttle it goes away and it only does it when im loaded. or atleast does it really bad. im bad at sound effects but the motor makes the same sound as a tire with a flat spot going down the road, but when u let up on throttle it goes away.

its almost as if the motor is being restricted, like when a motor starves for fuel. ive talked to someone who owns a 2011 cummins and he says hes motor does same thing and its a cummins thing.

there is no way in hell its normal lol

so motor has 435k miles ish and i watched all the videos on this site and while i was out there today i pulled the map sensor just to see because it was easy to get to and its one bolt and the sensor had carbon build up, i would say over half the sensor is closed up with carbon.

no one is open today that sells carb cleaner so i will have to wait till tomm.

also i had to add half a gallon of water to rad, first time i had to in last 12k miles of owning truck.
