    I had a similar problem, but it would run very rough... Turned out to be a faulty wire on a vacuum sensor. Took 2-3 weeks of driving before engine light came on to pull a code and a good 2 hours to search out the faulty wire.

Most common failure is crank sensor. Before running out and buying one, I strongly recommend that you do some further testing. Any decent manual has instructions for testing systems. Also: test both running and after it dies. (while running everything may check out as good) If you have spark when not running, check fuel filter as well!

1995 jeep grand cheerokee laredo 6 cyl. randomly dies then takes anywhere from five minutes to hours to restart


The only component I know of, that shuts a Jeep off while idling or driving 40mph down the road, is a bad crank sensor. Usually when it starts going bad, it will sporadically shut off, like yours does. Eventually, it will just die and the Jeep will not start at all. Have it tested and replaced, if necessary.

1995 jeep wrangler just stops running without warning.


A bad crank sensor will shut the jeep off suddenly, while driving down the road, then restart later and it repeats over and over until you replace it.

Starts up like normal but jumps up to about 3 grand on the tach then falls down to 1.5 and stays there, engine surges at this idle. Runs good on the road till u have to stop and surges(jumps a little)....


P1294 indicates a vacuum problem or a idle motor control problem. Since you already checked for vacuum leak then the iac on the side of the throttle body will need to be removed and cleaned. The best thing to do is remove the whole throttle body so it can be cleaned as well - both with carb cleaner. The idle solenoid (motor) on side of throttle body should be removed to do a through cleaning. All of the black needs to be removed from inside both before remounting to the intake. Make sure all connections and bolts are tight before starting engine.

When idling my jeep overheats. The cooling fan is running and it speeds up when temperature goes up. The temperature gets close to 260 degrees and the engine tries to stall. when I start moving it cools...


At idling speed an engine does build up a lot of heat and the cooling fan will kick in. In slow moving traffic or traffic jams the temperature gauge can touch the red - particularly on hot days. The reason it cools down when you start moving is because of the air flow through the radiator.

Presumably there are no leaks from the cooling system otherwise you would have mentioned it. In normal circumstances the fan will not be running as you are driving at speed, as the air-flow through the radiator is sufficient to cool things. The fan only kicks in to get rid of excess heat - and this usually occurs at idling speed or after you have parked the car.

If the fan is running all the time as you drive, this points to either a fault in the fan switch, or the car is running too hot. presumably in normal driving the fan isn't running and the temperature gauge reads normal?

It is common - in stationary traffic many cars overheat (particularly big engined models) try to stall and 'cut out'. Restarting can be difficult until the engine cools down.

Is your car overheating in normal driving conditions or just at idle speed? Overheating in normal driving conditions can be caused by things like a failing water pump, blocked radiator, collapsed hose, faulty thermostat or, in the worst case scenario, cylinder head problems.

Overheating at idling speed is 'common'. Check your coolant level. If your car isn't using/losing coolant then there probably is no major problem. You can flush out the cooling system and refill with new coolant - and also check your radiator. Are the cooling fins crumbling with age? Or maybe they're partly clogged with insects and debris from the road? A blast with a hosepipe wil sort that out ..

The question is how much does your car overheat in normal driving? If it doesn't .. it appears as though you have nothing to worry about as such. Most cars have 2 speed fans... the 2nd faster stage kicks in at some point dependant on engine temperature. Perfectly normal.

My 2003 Jeep Liberty Limited Edition blows out cold air while im stopped at a light or stop sign or whatever. But as I drive it will blow out warm air!! Can someone please help me with this problem!!!!


Yea, theres an air bubble in your coolant system. Check your coolant level, and top off the fluids.

When your jeep is going down the road the water pump is cycling the coolant, but when you are idling there isnt enough spin on the water pump to push enough coolant to compensate for the air in the system
