2002 Jeep Grand Cherokee with the 4.7L.
The Jeep will stumble and bog down under load, especially when going up hills and I'm having trouble pinpointing the cause. Seems to get worse after it warms up. City driving is fine but not highway speeds. I've searched hi and low online and have yet to figure it out. I've read it could be moisture in the transmission, maybe one of the coils going bad, TPS sensor (which I have replaced). Check engine light is on for an evap leak but I don't think that would be the cause? This Jeep is my winter beater and I'm trying to diagnose the problem without throwing parts at it.
Anyone here ever run into this? Thanks.
