Re: P0303 and Coolant
So just from the P-code you've already determined it's a spark issue.

Re: P0303 and Coolant
Yes. What would you deduce from a P0303 code?
HINT The code means the #3 plug is not firing properly, which by definition is a spark issue.

Re: P0303 and Coolant
Thanks for the responses, guys. I cleared the code last night and drove
about 20 miles, it hasn't since returned. I'll change the plug today anyway. There are no plug wires on a 2k. Instead, there is a coil rail with three coil packs. The P0303 and the coolant are completely unrelated issues, I just posted in one post to keep the clutter down. My research has shown that the P0303 problem is known to be a heat soak issue with injector #3. Apparently, sometimes the heat from the exhaust manifold will creep up to injector #3 on a hot shutdown, causing a misfire. The fix is an insulating wrap around injector #3. The coolant in the radiator right now is brown. I assume someone drained the radiator and re-filled it with standard coolant. That's why I want to flush the system. I read that there is a 7-hour flush. Apparently I just add it to the radiator (after draining a small amount, of course), and it cleans the system during a seven-hour drive. I'll be driving back over to Seattle next weekend (a five hour drive) and I plan to change the coolant while I'm there. Am I barking up the right tree here? I have seen positive results with using water wetter in an all ready good cooling system. I would not expect to see results using a it in a clogged, contaminated, or otherwise maulfuntioning system. Per reccomendation here, I will not add it to the XJ. Just curious why they say not to use it?

Re: P0303 and Coolant
Brown coolant is undoubtedly bad, but it doesn't necessarily translate to
scale and sludge in the coolant chambers of the block or blocked radiator tubes. I would flush the system with water, and only resort to a chemical flush if big pieces came out. Otherwise, you can assume that most of it is already in suspension. Another tell-tale is the bottom of the overflow reservoir. Nasty pieces will tend to accumulate there because it doesn't really have circulation. I am against flushing with chemicals unless you have reason to believe that they are necessary, and then you have to take extra care to rinse them all out afterwards. When you say "positive results with using water wetter in an all ready good cooling system" what do you mean exactly? Lower reading on the temperature gauge? I don't get how you can tell, that this stuff is doing what they say it does.

Re: P0303 and Coolant
Brown coolant is undoubtedly bad, but it doesn't necessarily translate to
scale and sludge in the coolant chambers of the block or blocked radiator tubes. I would flush the system with water, and only resort to a chemical flush if big pieces came out. Otherwise, you can assume that most of it is already in suspension. Another tell-tale is the bottom of the overflow reservoir. Nasty pieces will tend to accumulate there because it doesn't really have circulation. I am against flushing with chemicals unless you have reason to believe that they are necessary, and then you have to take extra care to rinse them all out afterwards. When you say "positive results with using water wetter in an all ready good cooling system" what do you mean exactly? Lower reading on the temperature gauge? I don't get how you can tell, that this stuff is doing what they say it does.
