So i finally pulled the injectors out on my uncles 96, we thought for sur it needed new o rings. Pulled the injectors out, started looking at them and noticed that there were only 3 injectors with the right o rings on it. They had different sized o rings and rings in the wrong spot. One was a Reman and it was the worst! The metal ring at the top of the injector was under the 2 o rings it shoulda been on top of! Anyways, truck runs great now! I guess its a lesson learned on who you have your mechanic work done with.

 

humm who worked on it last?

 

Truck hadnt been touched since we bought it.. so we have no idea
