My '91 XJ is a 4.0L HO 5-spd, and has been running awfull funny lately.
It ran great with lots of power, and then the problem started....this was not a gradual thing.
I went through a couple of moderately easy, though bumpy mud trails with my buddy a couple of days ago. On the drive home I noticed a lack of power when i would step into the accelerator. It almost felt like some kind of driveline drag, except that it was not constant. It starts stumbling during acceleration at about 1800 rpm's, and will randomly run very poorly while cruising.
*I replaced the fuel filter, and the air filter is clean. The fuel injectors don't appear to be leaking, and have very obviously been replaced somewhat recently. I checked for vacuum leaks in a few places, and intend to do a more thorough inspection tomorrow when it's light out.*
if anybody knows what this is, or has an idea what it could be, I'd love to hear from you.
thanks
