For a couple months now my Jeep will **** twice and then act normal when I would first start off driving after it had sit for at least a couple hours. We figured it was just cold. But this morning I went to pull out of my subdivision and my jeep wouldn't go but the RPM's soared and you could hear the engine trying to make the car go. I checked everything to make sure I was in drive and everything was fine. Still the same results. So I put the car in reverse to try to get back home and the car would only crawl back with RPM's soaring and engine reving. I finally got turned around and put the car in drive again. It started to creep along with the RMP's soaring and the engine reving. All of a sudden the car **** very hard twice and jumped forward going at normal step. I drove around the block and it acted fine. Does anyone know what is going on or has had this issue. I have not service lights on or anything. I am taking it to the dealership but they said they might not be able to figure it out if the Jeep doesn't do it for them. Please help, this Jeep is the vehicle I use to transport my children so I want it to be safe. Thank you

I had a skim module go out in mine in the ignition, and I have a 2001. It's a 100 part, and now it starts fine.

I would check to be sure that the timing chain hasn't jumped at all ..
SOURCE: transmission issues (I think)
Use a engine scanner to pull codes, If none it sounds like the lock-up torque converter may not be disengaging at idle. Or you have a idle air control valve or TPS going bad, then repair codes by replacing failed sensor or shift control solenoid as needed. If no codes are present your transmission could have a internal failure. It's also been know that oil transmission fluid in the system will have a higher fluid retention causing the 2nd gear solenoid to stick causing the transmission to stay in second till the line pressure rises and drops back to first with a hard shift. Keep me posted be glad to get your transmission running again.
SOURCE: I put my jeep in reverse and it stalls. When i put it in drive it
check your plug wires and it wouldnt urt to check the distibutor car and rotor
SOURCE: Hard starting when cold ( engine cranks normally )
see if your engine has a ECT sensor (temp sensor that delivers information to your ECM) they are installed on the intake side of the cylinder head, it usually has 2 cables, have it checked replace if necesary
