I REALLY DO NOT THINK THE WATER-PUMP IS YOUR ISSUE, IF IT'S LEAKING, SURE IT NEEDS TO BE REPLACED, AS IN ANY OTHER VEHICLE.
IMMA CJ KINDA GUY AND I'M NOT UP TO SNUFF ON A LOT OF THE COMPUTER STUFF, HOWEVER I DO KNOW SOME OF IT. (I COME OVER TO THIS FORUM SOMETIMES WHEN THERE ARE NO CJs TO FIX, OFTEN, CJs SELDOM TEAR UP!)
I'M JUST TRYING TO HELP OUT, MANY DO NOT EVEN GET AN ANSWER.
I KNOW CJs VERY WELL, AND I DO WORK ON FRIENDS AND FAMILY VEHICLES, I RESEARCH THE STUFF, I'M LOST ON. AND GENERALLY GET-R-DONE CORRECTLY.
I'M A SELF CERTIFIED REAR LAWN VEHICLE TECHNICIAN, AND REPAIR MANUALS HAVE BEEN MY BEST REFERENCE IN DIAGNOSING AND REPAIRING THINGS I AM UNFAMILIAR WITH. I DO HAVE A REALLY GOOD MECHANICAL BACKGROUND, TOOK AUTO MECHANICS IN HIGH SCHOOL (BEFORE COMPUTER STUFF) SO I CAN USUALLY UNDERSTAND WHAT THE MANUALS MEAN, OR I RESEARCH THAT TOO.
SO MY BEST GUESS AS TO WHAT YOU SHOULD DO FOR YOURS IS
1) IF YOUR CHECK ENGINE LIGHT IS OR WAS ON, TAKE IT TO AUTOZONE OR ADVANCE AUTO OR OTHER, THEY CAN "CODE" YOUR VEHICLE (FOR FREE!), AND NORMALLY THE EXPERIENCED GUY THERE CAN DIAGNOSE YOUR PROBLEM (KNOWING THE CODES) SHOW YOU WHAT TO CHANGE AND SELL YOU THE PARTS.
2) MY WIFES FORD ESCAPE HAD THE SAME ISSUE AS YOURS----THREW NO CODES!---
Her Escape would idle low, then it got to point it would die when you stopped. Revving + holding brake was only way to keep it running. Took it to fellow R/C airplane pilot, he doubles as a S.C. State HWY DEPT mechanic.. When I got to his house, he was repairing a tractor. Told him my sob story. Escape was still barely running, I raised the hood. He said, (and I quote)."It could be the IDLE AIR CONTROL(IAC)", as he pointed to it, and emphasied it with a sharp rap using the wrench in his hand. It straightened right up, and ran darn good!
HE SAID IT COULD JUST BE CLEANED, SO WE DID. That was a 15/16 Craftsman wrench, box end, kinda a medium rap. YES, I visited parts store and replaced it. This is my wife's rig and I take no chances with her. Or the "Wrath of Margaret", should she break down on my watch!
YES, I KNEW SOMEONE WOULD WANT TO SEE HOW "DIFFICULT" THIS WAS. I ALSO FIGGERED THAT IT HAD BEEN ON HERE SINCE 2002-2003, IT WOULD NOT HURT TO HAVE A NEW, MAYBE NOT WORN OUT DEVICE ON IT, EVEN IF IT WAS NOT THE "FIX" (THATS HOW I JUSTIFY STUFF TO MYSELF, ANY WAY)
The Ford was right on top, 2 bolts, unplug the wires, less than $50
Let me know if this helps
