I went for for it! Brought her home today.

4 hour straight drive from dallas to south austin enduring waves of misfires. Scary at first, but then I got the feel for it and just kept driving.

Temp stayed at 200 never moved.

Oil pressure stayed at 51-2 never moved.

Voltage stayed at just under 14 also never moved.

Gas went down LOL.

Every time it started missing I would release the gas pedal and it stopped. Then started up again.

After about 2 hours "about half way home something weird happened... While missing the AIRBAG light came on then Spedo, fuel and Tach dropped out. above guages stayed the same. this occured for maybe a minute... no misfires. Above guages stayed the same. Then (after the minute) the AIRBAG light went out and Spedo,Tach,Gas returned to normal. Didn't happen again.

Started to wonder why the check engine light was not on "maybe disabeled???" Well got to north austin "about 45mins" from home and the check engine light popped on.

Made it home. Misfires and all. Never stopped. Wheww!!! Thats all I wanted for now.

When she wasn't missing she drove-sounded-responded Great.

Tune-up tomorrow. We'll see?

Thanks guys for all your suggestions/help I will be doing pretty much everything you guys advised.

Cheers! I now have a '99 4.0 4x4 XJ that needs some love.

 

Change the crank sensor while you're doing the tune up, and you might as well replace the cam sensor (AKA the pickup coil) too.
