Either your heater core is plugged up or your line to the core is restricted. Do a complete reverse rad flush with a radiator cleaning solution and try it. If that doesn't work you'll need a new heater core.

Is battery fully charged? These new fuel injection cars are very sensitive to battery status.

I doubt its a fuel pressure issue being at idle or at a stop sign is the lowest required fuel pressure during operation other than coasting. Sounds more like an an idle control problem What motor do you have? Auto or manual trans? Need more info about rhe vehicle to point you in the right direction.

If the timing belt were broken, the car would not be driving at all. If those codes weren't confused with another symptom it could be the car needs a tune up. You should think of when the last time plugs, wires, air filter were replaced. If they're pretty new, it could mean a cracked cam shaft sprocket has the engine out of time. Honestly, a full tune up would be cheaper than paying a mechanic to tear down and close up the engine. Good luck!

It would help to know if fuel pressure drops when it fails, or if spark drops out. You could hook up a fuel pressure gauge that you can see from the driver's seat, and use a real time scan tool to see what is happening when it fails.

Sounds like a fuel pump. Some times when the pump is getting ready to quit it will work intermittently and then quit entirely.

what country?, UK jeeps use diffr rad's and diff, methods...... there are more than one radio (orig) sold with car. we cant guess the model !@ if you look and read the model there and google you WILL find out how to set it. FSM for 2000 USA shows no mention of codes. http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service do you have the wrong radio in the car off a newer Jeep? the radio sticker on top tells you year, and model and serial. all key to finding this method. but just the front dial has the 3 letter model code.... what is yours. models RBN, RAZ, RAS? on the face plate it is.... look see it? http://www.radio-code.com/Dodge_chrysler-Pay-Page-radio-code.htm ask here.? http://www.wranglerforum.com/f40/res-radio-security-code-151132.html the operators guide may have this answer. lost yours? button presses.... are there, if needed.. rules: also never pull. the OID fuse with key on, or the radio scrambles. to fix that error, key off pull that fuse, count to 50 put back. if you guess 5 times the radio locks for 2hours some newer RADS have a rule that if you guess too many times' it bricks forever. (needs service center fix $$$$) some codes do not exceed 5. 0 to 5, in this case 8898 is not a code..... so whats with that number? and last this great site on head ends http://www.allpar.com/stereo/head-units/ see what radio you have, then ask. and post the error codes on the display ("wait") or what?

you will have low or no compression. The car will overheat. The oil will be contaminated by water. It will not pull very well. It is fairly obvious and easily diagnosable with a compression tester and a little know how Good Luck

Check the three main grounds. Battery to engine, battery to body, and engine to body. If you cant find one, add it.
