what does your code say. do you have a cel showing? make sure all of the wire are pluged in tightly. i would check to see if CPS is properly installed.
welcome to forum, i am sure that lots of people would like to find a wrangler like you have. where it rare or not, some one else with more history could tell you. i hope you get many yrs of enjoyment.
that a GOOD looking machine. you can be commented for the good work that you have done. why are you even thinking about selling. the cyl that it seems to drop, change out the injector to another place and see if it still happens. maybe just a bad one. keeping driving till it get worse? run you...
thank you for follow-up. do you think that you could sent a message to Fel-Pro and see if they still make the gasket, may be just a mistake that they dont list.
let me make one final suggestion. if you find a good wrangler that you want to buy. get with the experts on this forum, let them tell you what areas to take pictures of and have them view. they can tell you what is good or bad. happy hunting
