Dando Posted November 30, 2015 Share Posted November 30, 2015 So last week I was driving on the freeway and the jeep overheated, stuck thermostat. (1990 MJ with 4.0 aw4 231) I blew the head gasket in the process. I replaced the head gasket and put it all back together. Had what seemed like an intake manifold leak and I tried to redo that Saturday. Now it idles at the right rpm, but it just drives like $#!&. Won't come out of first gear, lack of power, sounds like there is an exhaust leak but I can't find it. What can cause all these issues? What did I do wrong? Truck was finally starting to run great before the head gasket. I am broken down currently at a job site for work, need to figure this out please please any help is appreciated Link to comment Share on other sites More sharing options...
Dando Posted December 1, 2015 Author Share Posted December 1, 2015 through this entire process I never replaced the intake manifold gasket, I reinstalled the one for over a year ago now, should I have replaced it? Do they always need replaced after manifold removal? Link to comment Share on other sites More sharing options...
