No egr on my truck then. Ok the codes came back, but only after like 200 miles of driving, before it was coming on like every 5 mins. When im on the highway in 5th i can feel the converter trying to lock, but it wont engage, this makes the truck feel like its starving for fuel and it bucks a little. This only seems to happen when its raining out. Could this be symptoms of a bad converter, or should I be looking at the speed sensor/wiring?
