Hi, I drive a 99 WJ 4.7L. Everything is nice on my Jeep except
that a few weeks ago, the WJ bucked once.
I lost the data on the evic, the radio cut, and the engine bucked, but only once. all of this at the same time, and it lasted a second, not more. then everything came back to normal. the radio came back, the evic also.
Then, nothing for a few weeks. then it came back......exact same thing. lately, it got more often. from once a week to two or three times a day.
always the same story. no evic no radio and i feel a 'power cut' or a buck in the engine
in the last days, it could happen twice in 10 seconds.
However, the engine never cuts out completely. It gets back each time.
but sometimes, i use the jeep and nothing happens for a day if im Lucky. Last week, I had all the symptoms, plus the chime got on.
Ive read about it, spoke with jeep techs, etc........They know NOTHING
My guess would be the crankshaft pos sensor, a faulty ground somewhere on the car (go figure where is it), a short or maybe the pcm (heard about the zipties but didnot try).
I replaced the battery and verified all connections. I lately installed a ground kit (big 3). It did not cured it. I checked all fuses, relays, and everything and cant find nothing.....NO MIL....Im puzzled
ever happened to someone in here ?????
