This thing is killing me. So I am driving the other day and the jeeps starts to kick and sputter sparatically. I had somethig else going on at the time so I just got it home and parked it. I looked at it on Sunday and found a check engine light. I pulled the codes and got three of them. 33, 41, 51.
According the hayes manual 33 is Ac clutch relay ( don't have ac), 41 is generator voltage low, and 51 was o2 sensor voltage sensed low (new sensor). I also found the conncetion to the coil slightly loose (the lock is broken off and is held on with a zip tie.) I tightened the connection and thought that was the end of it. I took the jeep to work today. I started the jeep this morning, CEL lights were cleared and everything was good until about 35 to 40 minutes into the commute. She started again. by the time I got to work the CEL light came on again and it was bucking and kicking. The same three codes are logged. I noticed the electrical indicator was also low, around 11v. With the code 41 and low voltage, I am thinking alternator at this point. Does this sound logical? It is about the only thing left under the hood that has not been replaced or rebuilt in the last 4 years.
