In 2010 I purchased a beautiful '98 Wrangler Sport,from an elderly lady that had only 51k miles.It had a 4.0 with air and auto transmission.Within a week,the jeep would for no apparent reason,begin to stall and miss.This episode would last anywhere from 45 to 60 seconds,and by stomping on the gas,it would backfire,and then smooth out.In the last 10k miles,I have spent approx. 2500.00$ trying to resolve this problem,including 1300.00$ and 18 weeks at the Dealership.After 4 and 1/2 months,I brought it home today,same problem.After owning four Jeeps, this is my last.
Nothing.I have never been so disgusted with a vehicle.
Good afternoon Pwayne .your stalling and all around lack of power is surely caused by a lack of good fuel pressure .that is caused by either a faulty fuel pump , clogged fuel filter .it could also be caused by a fuel pump relay that is getting warm and cutting voltage to the pump . Don't give up on your jeep yet !!!!
