OK here is what I have going on my wrangler is a 94 I haven't ran the vin or anything but it does have the external slave. Problem is that so far I have had to buy engine parts for a 93 like the AIT sensor and a rotor for a 94 doesn't fit. Now I did the cam sensor a while back and it hasn't run right sense well I bought one for a 94 could this have been the problem? I looked up distributors and the one for a 93 is different and it is the one I have in mine now. I am going to replace it which one would you guys buy?
