I drove the new XJ I just bought last week for quite some time tonight and came across a few problems I need help with. It is a 1990 4.0 with the automatic and 242? (part time and fulltime) transfer case. There are 140K miles on it. Also just so you know the exhaust is shot. Some of the problems I think may be from lack of backpressure but im not sure. First of all, sometimes when accelerating, the engine almost seems to cut out for a second before it takes off. Second of all, at some times when idleing or reversing then switching to drive quickly it stalls out. Third of all, when the engine is heated up and has been running for a while there are times when it does not want to accelerate and wont go over 2000 rpms. It sputters and feels/sounds as though it is misfiring or knocking or something rather. This is my main concern as it was happening on my first cherokee when I decided I should get rid of it. I am new to working on cars.
Also I will be changing the oil tomorrow (my first time ever changing the oil). Any tips? What all tools do I need? I also plan on doing a tune up within the next week. What all do I need to do for that? I have a basic mechanical knowledge so this shouldnt be too tough but I have no hands on experience (which was evident when i changed my alternator in my TJ lol). Also, aat 140K what are some things I should check/replace. I want to get this in good running condition so I can get it on the trails asap. Thanks for the help in advance.
