I have a 2007 jeep grand Cherokee with a v-6 engine. The problem I have is when I start driving up a incline about 30 miles per hour or so the engine will drop power almost like the fuel shuts off. As you push down the gas is just bogs. When you back off a little it will all of a sudden take off. I also want to mention it does not do it all the time.
