Car wont stay running

replace fuel filter and if it continues have pump pressure checked

check for a fuel flow problem( pump pressure-filter blockage-injector/s) run fault codes ( check for HO2S and O2S sensor operation.. Check cat converter is serviceable Blocking exhaust system

hello ther I belive it is your ecu very common

Have you checked your fuel pressure? Could be the fuel pressure regulator. Hard to say without a year and model of the jeep.

does your temp gage seem off does it go like up to the h because if it does you could try unpluging your upper coolent sensor because that could cause that because it is telling you computer to run in closed loop when it should be running in open loop

pull off the transmission transition switch wire pluged on to tranny
start car drive should be fine never hook op again 0 money
or pay 700 dollars to install a new one
or buy switch pull tranny and install your self

sound like your have the bad distributor, when you have trouble starting remove the distributor and have the auto part check it.

souds like the choke is staying on too long , did you check the chokevacuum pull off they often go bad

is it carb, or efi ? and what size engin?

Good Day,

That could be caused by the TPS(throttle position sensor), or MAP(manifold absolute pressure sensor), is yout check engine light on? If it is it probably a sensor. If not it could timing, a vaccuum leak, or other possibilty's. What size motor? The 4.3L or 5.7L?

Let me know I can try to assist further.
