I replaced the camshaft sensor but still have a problem with the jeep
stalling. Now it is running very rough. I have a new code which states the
map sensor is bad. I checked the voltage on the map sensor & got 5.8.
I hooked it up again & got a code PO108 which is voltage to high.
Is the m ap sensor bad causing the high voltage or is it the computer
causing the problem?

How many miles, what engine?

Rough running and stalling are symptoms of a bad CPS (crankshaft position sensor) in the 4.0

Rough running and stalling are symptoms of a bad CPS (crankshaft position sensor) in the 4.0

It is a 4.7 V8 engine. Has 120000 miles on it.
when it was running good & started stalling it gave me the code "camshaft sensor". When i changed the camshaft sensor it started running real rough & stalling. Now it is giving me the code "map sensor".
I will change the crankshaft position sensor first before I change the
map sensor.Thanks for your input.
Any other suggestions would be appreciated

Before throwing a lot of parts at it, how long have the spark plugs been in it?

are you sure you are getting 5.8 volts at the map sensor...it's only a 5 volt supply so you should get 5 volts max unless your shorted to voltage...with the key on remove the map sensor connect a volt meter to the signal cicuit and apply vacuum check if the voltage changes..

Any other suggestions would be appreciated

Keep the TPS as a thing to check as well. I had similar symptoms and a new TPS fixed it all for me.

Thanks for the info. It will be a week or so before I'm able to work on
the jeep again. I will get back to you asap.

Thanks for input...I'll be sure to check it as soon as I can work on the jeep again.I'll get back in touch.
