Gas guzzling beast

[Rubicon Josh]

Hey guys! Haven't been online for a few months (since I moved to Edmonton) and I really miss all the weekend adventures we had down there. Hopefully I'll be able to get in touch with the club next time I'm down there. I had a little incident involving a 5 ton truck, the shop wall, and my jeep so repairs are the order of the day. It just happened that the accident coincides with AEV's release of their highline kit. I can't wait to see how it turns out.
The reason why I am posting however, is that in the last two months my fuel mileage has gone from approximately 600+ km a tank to 250 km a tank. The jeep dealership has told me that it is deffinately dirty injectors, and has quoted me between $800, and $2000 to fix. The problem that I have with their diagnosis is the rate of speed that the problem has got worse. Just wondering if anyone else has had similar problems, or if anyone has ever removed their injectors and cleaned the tips themselves. My haynes manual makes the job seam relatively easy, but you never know until you get things apart what kind of mess you got yourself into.
Thanks for any help and advise you give.

P.S. Miss the mountains, Edmonton sucks.

My YJ's mileage did the same thing. Turned out I had a plugged cat and a bad O2 sensor.

I had a similar problem as well, but unfortunately I still have not found out what it is.  I had mine down at a local Certigard and the injectors was the first thing they checked but mine were okay, however they did a complete fuel system flush for pretty cheap, < $100.  I would not go the dealership and spend that kind of money.  What was included in that quote?  I would check around first, because if you screw up an injector I don't think they are the cheapest to replace
