For the last couple weeks my 4.0 has been doing something strange. After being driven long enough to come to operating temperature, if I park it for a while (10-15 minutes) and then start it and take off again, it stumbles while trying to accelerate and acts like it's going to die though it never actually does. If I back off on the throttle for a few seconds it then clears up and runs normally. If I start it cold and take off it will run all day with no issues around town or on the highway. Plugs new about 5K miles ago. I replaced the distributor cap, rotor and plug wires yesterday as the cap and rotor were somewhat pitted. That didn't change anything. I had planned on changing the crank position sensor anyway since it has 180K on it so I did that today. Again, no change whatsoever (but I have a spare CKP now just in case). No DTC's are coming up at all. Any ideas on what might be causing this or how to troubleshoot it with no DTC's showing?
Thanks, Steve
