I have a 06 5.9 Cummins. The other day I noticed that the engine revs high and when I put it in reverse or drive it jolts up to either 10mph then then idle back to normal and is drivable afterwords but when I put it in neutral it'll rev high then idle low. And maybebsometimes itll stall out. I don't know what it is. I hear PPS or TC. But yeah when I turn it on its normal but once I shift into D or R it'll go fast up to 5/10mph and when I try to brake it won't stop all the way unless I slam the brakes down and it'll rattle the dash a little like Its getting too much gas to stop. Please help!!!!?

 

Got a rail pressure gauge? Get one! Possible FCA, TPS or Pressure sensor. Do you have any codes?

 

Awhile back I got a code for a obd2 sensor and governor sensor but those went away.

 

TC is bad. Replacement time.
