Hey, after installing my long tubes the truck ran fine. Later that night I took the truck out and it ran fine all night in the snow, randomly the truck started to hesitate and backfire and stumble. Also had a rough idle. I have the egr deleted but I do have the o2's on the headers collectors. I made sure the plug wires were in the right spots on the cylinders and coil. I did have to extend the o2 wire on the passenger side to reach the collectors, I just crimped the wires on the o2 in order to extend it. Is there a possibility while driving those wires on the o2 got wet and then fried the o2? Or am I completely looking at the wrong thing? Also now when you start it up it runs rough and stumbles as well as backfires but only when it is cold. Once it heats up to 150-160 degrees the truck runs completely fine. What is wrong with this thing!!??
Thanks
Greg
