I got a 2012 peterbilt 386 ...it just came back from the shop a few day ago to get injectors 4 and 5 looked at and repaired ....I'm getting a fault code for injector spill valve and a engine light ....I tried resetting the computer to get rid of the code but that's not it ... uld timeing of this cause the problem ...but other than that it runs like a champ so what could I do to fix this is it time cause I did probably get re timed when they repaired it
The fault for the spill valve is not something you can correct with timing. When they repaired or replace injectors they need to be programed into the computer so they match the other injectors. The spill valve is in the injector and is there to return unneeded fuel back to tank. If this valve does not work you could be over fueling or run the risk of fuel cooking in the injector making a mess of the spray pattern. It should be telling you which injector is throwing the code and if it is one of the two that were worked on take it back.
