1994 Jeep grand cherokee with engine power loss problems when driving?
my jeep grand cherokee with engine 4.0l mfi will start from a little below 12v and drop down rapidly to below 9v depending on the outside temp.when really cold the drop is slower than when hot and then it starts to stall and the check light comes on and
My 94 Cherokee was doing the same thing. In my case,the crank sensor needed to be replaced. My mechanic said it was a common problem with Jeeps.
