Well after the number of times the onboard welder came in handy during the PNW Jamboree it is my fav right now.

I do not see where the water pump was any issue. When you get it running again and if it still o/heats, hold the rpm about 1700 and take an infared thermometer and hit all the exhaust manifold ports and look for one or 2 significantly higher than the rest. Look for a vacuum leak going there. With the o2 just reading the overall mixture coming out it will make the fuel mixture richer to compensate for the lean burn condition and make it easy to see the differance.

Gary,
Yep it probably wasn't the DAMN water pump. I swear I tested that stupid rad cap before but when I had the front tore down I tested it and guess what?? :wtf: :wtf: Yep you know it, IT WAS BAD!!:looser:
So I now have a Flow Kooler water pump on my Jeep. :cheer: :cheer:
And a new radiator cap. :redneck:
Gary,
I am at wits ends as to what to do about this lack of power. I mean the Jeep is a great trail rig and does fine off-road but it SUCKS onroad. I drove it down to Thorp last night to see if it would overheat and it didn't. But coming back up the freeway when I hit that S turn hill where it splits into 3 lanes I dropped to 55MPH!! And that just doesn't make any sense. Other than a Dyno do you have any suggestions? I am going to get a performance reprogram on my ECM and see if that helps.

Don't you think that you should 1st see if there's a problem with the motor before reprogramming the computer?
Does it show any codes?
Besides the lack of power does it have any other symptoms?
Have you looked at the factory manual for troubleshooting advice, check voltages and resistance readings on sensors, etc...

Well I have tried everything ELSE. No there are no codes. No other symptoms other than a lack of power. I have gone thru the factory troubleshooting. And there is an issue with the factory ECM's called the death flash. It was a flash they did to limit power from the factory. And there are two ways to get rid of it. Get a custom flash or get a reprogramer and do it yourself.

Don't know if you have to be a member to read this or not.
Every sensor checks out.

How about a simple compression check? Just one more thing to do before spending $$$

160-165 accross the board.
Vacum is good & fuel pressure is 45-50 PSI. I am trying to think of anything else your going to ask about.
