Question about 1997 Jeep Grand Cherokee
Engine dies all the time! Blew out muffler twice.Replaced muffler and catalytic converter with o2 sensor. Still stalls out and backfires.Some days no problems at all.But most days still dies 2 or 3 times on 18 mile drive to work.Will backfire on expressway and die out.Sometimes it will start right back up and other times take 5-20 minutes to get started.It has 200,000 miles and plugwires and plugs were changed about 75,000 miless ago.Does not have to be hot for it to die on me, weather or engine temp.This is very troublesome for me! Please help!
Since its a 1997 your jeep has EFI, electronic fuel injection. The most probable reason for your troubles would be the injectors or a problem with the computer controling them, not allowing enough gas to be pushed into the cylinder causing stalling or lack of power, also too much gas iin the cylinder can lead to back firing and stalling. This would also explain the reason it takes so long to start back up some times, all the excess gas in the cylinder is flooding the motor and u have to wait till the gas disipates till the engine will turn over.
