I bought this 1993 Jeep Grand Cherokee, 5.2 V-8, Fulltime 4wd
It runs great, drives nice until it reaches operating temp.
Then I intermitently lose O/D. In the mornings, It starts the first time your release the excellerator it shifts hard out of O/D from 60mph,
It works fine again for about another 15 minutes, then it will only shift to O/D after 65mph, and it takes another 5 minutes then I have to hold 70mph to shift to O/D. Shifts back to 3rd and won't have O/D until it cools back off.
5pm I only have O/D for about 10 minutes at 65mph and then its gone.Shifts great through all of the gears up to 3rd.
Then no O/D until morning. I'm Thinking now that the O/D band in the trans may be out of adjustment?

After all that Happens I start noticing an intermitent misfire. It sometime comes and goes quickly, 2 to 3 second interverals. sometimes more random. It kicks off the cruise control. Which I understand.
Wires, plugs, cap, rotor all new. Coil tested good. Could it be the Cam or Crank sensor?
The miss sometimes feels like a lack of fuel but other times it feels like a spark issue.

Any Ideas? I hate just randomly spending money on different sensors. It does have a new TPS.
