Neon Injectors questions.
Going out to the Junkyard on Wednesday, going to try to find some 703 injectors. What vehicles should I look for, and will I need to adjust the fuel map?
My brother seems to believe you absolutely will need to adjust something for it to work, and he is a WyoTecher so i don't doubt his knowledge.

(unhook your neg and pos terminals, hold them together for 30 seconds. Reattach them to the battery. Turn your ignition to "on", turn headlights on then off. Turn ignition off), then it will take 50 start ups for the ECU to relearn the fuel trim levels.

green goblin - nice copy/paste job from my post in jimbo's thread. Without the first part you can remove the parenthesis though. 
Just giving you a hard time. That's why we're here, to pass on knowledge.
ender - upgrading to the 703's (91-98 XJ's) or the 784's (99-01 XJ's) usually results in a smoother idle, better throttle response, and in some cases, slightly better mpg (though this one is actually pretty rare if the stock injectors were still clean). For the cost, I think it's a pretty good mod to do. If you want to do it but can't find the injectors you need, let me know. The pick n pull by me always has a ton of 'em.

from what guys that have done this said that there jeep. runs better and smoother. also better fuel milage because jeeps injectors have one hole. and the neons have 4 holes so better fuel atomization. heres a vid to give you a better idea

Thank you for the info!
Also, where could I pick up some new o-rings for them, cheap insurance as engine fires are bad.

Awesome, thank you for the help everyone! I will install them next weekend, so let them soak in solvent, then after install I will probably run seafoam with the gas. What would the average price be for two sets from a junkyard?
