Cherokee problem
My Daughter has a 1994 Grand Cherokee that has suddenly started acting up.
Here's her description of what its doing: "Couple times the car would not start normally. When driving, car accelerated normally to about 45 mph then sputtered until we dropped down to about 30 mph then would kick in again up to about 45 mph and sputtered again. Car doesn't accelerate normally, generally when going faster, but has happened at lower speeds. Cannot get it to go past whatever speed it drops to (i.e can't get higher than 30 until it kicks into a normal acceleration). When sputtering/stalling, sounds like metal churning (happened once today when it stalled). Also a clicking noise started in engine." I was thinking that maybe the Crankshaft Position Sensor was going, but I'm not sure about the sounds she's hearing. Any help would be appreciated.

At any rate, Did the CHECK ENGINE light come on? First, pull the codes and see what is on the ZJ's mind. http://members.cox.net/wilsond/engine_codes.html Metal churning/ticking.... hmm.... (I'd pull a compression test to make sure it's not internal) Check the distributor, it can make that sort of noise as the bushing wears out. A sure sign is oil in the base. http://members.cox.net/wilsond/distributor/ I did get a grinding noise once on my ZJ. Only during moderate to heavy acceleration. It was due to the main bearing failing and required the motor be short-blocked. (lower end replaced) The problem could be lots of different things, start with getting the codes. Heck, it could even be a clogged fuel filter. That will definitly limit your max speed and cause pinging/bucking.

Hi Robert,
That's your computer defaulting to it's limp, safe mode. I believe your CPS guess is correct, judging by my Brother's four failures.
