Hello Carolyn
what car, a jeep GC, sure, but what year, and what engine size.
jumps. (ill assume engine jumps and not transmission slips)
the engine can jump or many types of reasons, failures. 50 or more.
i guess you what us to guess, and not do tests and find true cause?
1: failure to do the service on the car is the all time top #1 reason.
spark plugs, and filters stop this list. every 60k miles or as the operators guide in the glove box states.
2: bad fuel. (or wrong fuel)
3: Bad TPS sensor.
4: low fuel pressure.
5: engine intake air leaks. (vacuum leaks)
6: bad MAF or MAP sensor,
7: ASD relay dropping out, for a second due to 7 errors it sees. ask.
8: 12vdc battery power dropping out for any reasons, (many)

2005 nissan murano jump started witnow it will only idle but will not accelerateh jumper cables reversed


NOT SURE WHAT YOU SAYING ? WHEN GETTING JUMP STARTED, THE BATTERY FROM THE GOOD VEHICLE MUST PLACE JUMPER CABLES ON BATTERY TERMINALS, THE CAR BEING JUMPED, YOURS, THE (+) TERMINAL IS JUMPED FROM GOOD BATTERY, THEN THE (-) JUMPER CABLE FROM GOOD BATTERY GETS CLAMPED TO YOUR CARS FRAME OR ENGINE BLOCK, NOT YOUR DEAD BATERY !!!!!!! YOU MAY HAVE SHORTED SOMETHING OUT, MAYBE EVEN YOUR COMPUTER CHIP IN THE ECM ! YOU NEED A MASTER TECH TO HELP YOU ON THIS ONE, I WOULD'NT TOUCH THIS WITH A TEN FOOT POLE ! SORRY, I COULD BE WRONG, BUT, NOT AN EASY ISSUE OVER THE NET !!!!!!
