hey folks, when i am going to pass someone on the highway and i hit 140km/h my truck has a fairly aggressive shake but nothing too concerning, but if i continue to accelerate to 160km/h it gets much more aggressive and I get a flashing CEL but goes away once I slow down. I know i probably dont need to be going that fast but its whats gonna happen haha. If someone could help that would be great! Thanks!

 

Out of balance wheel.. Bad u joint.. Bad hub bearing... A misfire in the motor.. It could be a number of things.. But with the CEL flashing its leading me to believe its in the motor.. mis-fire

 

hmmm well that just makes for more questions haha.

 

any codes coming up?

 

i dont got anything to pull codes with ill go to a local diesel performance shop and borrow something from them. It only pops up if i keep giving er but if i let off usually it ****s off right away

 

could always do the key trick to pull codes. key on-off-on-off-on then watch the mileage display

 

hm ive never heard of that before, i don think the CEL will stay on long enough for that

 

Just see if anything comes up
