My brother has a 90, 4.0, auto, XJ thats on the fritz. When you first start it up it runs great but as it warms up it starts to hesitate when giving it throtle and has a low ragged idle. The timing is on, has new plugs, wires, fuel/air filter. Any Thoughts or ideas would be great. Thanks, Dan "If you can't learn to do something well, learn to enjoy doing it poorly". 85 22RE, 5spd 4Runner project 87 Turbo Truck, Boost Controller, otherwise stock... for now. 86 Turbo 4Runner, Project Re: 90 XJ Runs rough.

Although there are others this is the main warm-idle psoosibilty.
