86customanche Posted January 21, 2010 Share Posted January 21, 2010 I have a 86 MJ with a 2.5L that is running very rough. :headpop: I took it to the shop and they said that there are multiple problems with it and that I'm best off finding a 4.0 straight 6 out of an older model XJ. I was wondering what you guys think are my choices for either fixing my small, underpowered motor or finding and replacing it with a more powerful one. :help: Quote Link to comment Share on other sites More sharing options...
