I replaced the o2 sensor. the old one was white. its been raining off and on this week and I've been real busy at work so I haven't had a chance to get out there and mess with it again. I'm planning on changing the fuel filter this weekend and see if I can "T" into the fuel supply line to get a pressure reading. This is the first time the Jeep has been driven in about 4 1/2 years, so I'm thinking there may be some gunk somewhere. Plus the alternator just crapped out on it so thats another $80 I have to drop on it.
