Stalling on freeway.
So I've had my zj for a while. Every time I drive on the freeway around 65-70 mph it's bucks and stalls. Like if it's cutting gas. I've changed the MAP, TPS, EGR valve, done a full tune up. I don't know what to do anymore. I've read about the PCM wiring harness on the I6 not making contact is this similar to the 5.2?
