been chasing that code for a couple weeks now in my 98 tj.. took it to an off road park .. and on the way home died on me..towed it home.. just wouldn't start .. changed both cam and crank sensors And it now starts but still running like shit .. but that's the only code it's giving me .. even went as far as cutting both ends of connections for the sensors and hard wiring them together with no change ..so finally decided to pull the distributor.. bushings are shot .. cam gears are worn down on it ,as well as the flat end where it inserts into the oil pump.. so there's some unwanted play on the distributor shaft .. so this video is definitely making me feel hopeful on this being the culprit.. will find out for sure once I get the new one.. thanks for the video
