Hey I have a 95 Nissan Pathfinder. About a month and a half ago I took it mudding and then accidently sunk it pretty bad. I've been trying all sorts of things to fix it. Right now it runs better than it did, but when it's still cold if i press the acelerator all the way down it boggs and trys to die. So far I've changed the spark plugs a few times, changed the oil, added additives and changed the oxygen sensor (that made the most difference). Does anybody have any idea what the problem might be? It has a 190,000 miles on it, and the check engine light recently came on (actually before I went mudding). Do you know how to check the codes on a 95. I don't know if it has a plug for OBD I and if it does where is it...or how to check it otherwise...thanks appreciate the help!
