1995grand cherokee4wd when truck is started it dies right out and won't stay running.


Hi Susan,
I would do a full tune up. Change oil. oil filter, air filter, fuel filter, spark plugs, plug wires, distributor cap and rotor. I know it sounds like a lot, but this is considered a full tune up. If problem persists let me know and we can go from there.

79 chrysler codoba ? don't think its a fuel problem ! I can't believe a cordoba ????????/ really ? I knew someone who had one, white w/ blue interior ! WOW ! after all these years, I need to wrap my head around this . give me a minute ! this bucking violently sounds so familiar ! I'm thinking electrical, BAD COIL, when it overheats, it comes & goes ! spark plug wires need replaced also ! what type of distributor ? replace cap / rotor ! whats in distributor , points ? electronic ? ignition module ? I'm so intune with todays cars, can't remember ! TIMING may also be an issue ! have you checked all the VACUUM HOSES ? EGR valve ? TODAYS FUEL is bad for this vehicle ! need I say more !

If you can determine the ignition system is ok, I would look at fuel pressure and the fuel filter. If the distributor was loose you may have to check base timing.

Dodge stratus misfire, runs rough has random misfires in cylinder 1,3,and 5 and a vacuum leak, I,m not too worried about the leak unless it is related to the misfire


I WOULD REPLACE DISTRIBUTOR CAP AND ROTOR.MARK LOCATION OF ROTOR OR MAKE NOTE SO YOU CAN INSTALL NEW ROTOR IN CORRECT FIRING POSITION. IF THIS CAR HAS A LOT OF MILES I WOULD REPLACE DISTRIBUTOR CAP, ROTOR.SPARK PLUGS AND WIRES.REPLACE IGNITION COIL.CLEAN FUEL INJECTORS, FILL GAS TANK UP TO 3/4 TO FULL TANK OF GAS POUR CAN SEAFOAM IN FUEL TANK IT WILL FLUSH OUT THE FUEL INJECTORS WHILE ENGINE RUNNING OR DRIVING CAR. REPLACE FUEL FILTER. REASON I SAY DO A TUNE UP PROBLEM COULD BE MINOR FIX.COULD NEED TUNE UP.IF TUNE UP DONT HELP THEN YOUR PROBLEM IS DISTRIBUTOR OR THE CAMSHAFT SENSOR INSIDE OF DISTRIBUTOR.THAT WOULD SET OFF CHECK ENGINE LIGHT.BUT I WOULD SAY TUNE UP COULD FIX PROBLEM.

Will not idle. i have replaced plugs distributor cap and rotor. i spray throdile body cleaner into carb and it runs fine until it evaporates


Sounds like a fuel problem. Check or just replace the fuel filter. If that doesn't help check the fuel pump. Check for fuel at the carb or injector rails.

Engine stalls out on occasion like the key was shut off have change air flow sencer mapp sencer new vaccum lines


Check your plugs, wires, distributor cap/rotor, fuel filter, and air filter.

If I had to take a guess, I would try replacing the Distributor Cap & Rotor, as well as the Fuel Filter. Also, try running some Gumout Fuel Injector Cleaner and a tank of good gas through it.

I hope this helps! Best of luck to you :-)

Best Regards,

James
