Did the problem start suddenly, or has it gotten worse over time?

What year is it?

How many miles do you have?

Manual or automatic transmission?

What engine?

How long since you got a new battery?

How many miles since you got new spark plugs (and cap and rotor if before '99)?


With the answers to the questions above we will be able to help you better.

However....

in general if you have the 4.0 Liter inline six, you could be having an issue with the CPS, crankshaft position sensor. It can cause hard starting and make your engine cut out, and in some cases, make your auto transmission shift wrong. Please post back with your answers to the above, so we can help.
