In reading many other postings, all the little things may be adding up...
92 Jeep Cherokee. 4.0 Fuel Injected, Straight 6. 187K Miles. Living in the Desert. Knocks at start up, but quietes down by 150 degrees, or I can turn off the engine and restart it and it is quiet. Intermittent Rough Idle in reverse or forward, but not in nuetral or park. Intermittent (but getting more frequent) cut out anywhere from 25-65 mph. Driving along just fine and the rpm drops to zero, (radio, etc are fine), then immediatley return. Shop says no codes. Possibly a power booster leak on hard brake.Any ideas?
