My check engine light came on today...I have 12-15 mile drive to work when I got about a mile from wrk... I was at a light and when it turned green I pretty much had to floor it to get it to go 5-20 MPH...then it just goes to normal no hill completely flat ...Then it was fine all the way home then boom it did the same thing. Truck has always ran great never a issue has about 130 k on it no perf **** just long arm kit and lift and 33' ...But that's been on for almost a year now...

 

Find out what code tripped the CEL. Most auto places will scan them for free...get the actual Pxxxx code, not their "diagnosis" of what the code means.
