97 tj 2.5L auto…Cel came on yesterday after a long drive, p1391… this happended last year and I replaced the cam position sensor, crank position sensor and timing chain, all mopar, and cel went away… checking everything out today I pulled the distributor cap and rotor and found that the distributor shaft has a very little bit of back and forth play, not much, but enough that you know it’s moving… should the distributor shaft be rock sold or is a little play acceptable… any other ideas?… Nothing changed about the way it drove yesterday, no miss, no backfire, nothing… I thought it was going to be the normal p0420 because I don’t have cats…
