So i have a 2013 freightliner mc2 rollback. Has 105,xxx on it.
Truck has this issue where say youre at a redlight and you pull out. The truck goes to take off, and then falls on its face. Itll almost like cough and repeat. Itll continue doing this cycle randomly until highway speeds. Truck also doesnt seem to have balls behind it as it did.
No codes
No lights
We initially thought regen issue and put it into a forced regen. It took. Didnt seem to help.
We then thought bad fuel, drained water seperator, no water.
We then replaced the fuel filter and added additive. No change.
That was yesterday. Today the truck still had the issue. Spools up, falls flat, spools, flat. Doesnt make a difference if loaded or not.
Got home to park the truck, and it went intonanregen again. I let it finish and test drove. Again no change.
Anyone able to offer any insight? No hidden codes, no cels, no codes, no lights, gauges and fluids normal. Pm was last done 5k miles ago. Fuel filter was done again yesterday. As well as new air filter, also checked all couplers and hoses. Air to air hose ok. No pin holes. No slipped clamps. Were all stumped. Dpf? Injector? Fuel trim? Vgt harness? All systems seem ok on the scanner. thank you in advance!
