I know there are a ton of threads on this, but user Programbo wanted me to report what kind of mileage I am getting after I swapped out my fuel injectors. (as I bought them from him - which the transaction was great, thanks!) I'm happy to report that the last three tanks I went through, I averaged 19.7mpg. I drive mostly rural county roads, with very little highway driving. My mileage has increased by over 2mpg. I was averaging 17.5mpg with the old injectors. The biggest change that one must make with the injector swap is driving style. That was a big one for me - I needed to learn that I don't need to accelerate as quickly as what I used to. So, with a lighter foot, and better injectors, I'm happy that I can report an increase in mileage.

On a side note: For those of you in cold climates (and warm, but you don't have cold, cold winters): Remember to check all of your hoses and your belt before the snow flies; you don't want to be stranded waiting for a ride when it's super cold out. It isn't that cold here yet, and last night my lower radiator hose decided it would fail, I had coolant EVERYWHERE, but thankfully I was right next to the Jeep when it happened, so I shut it down.

 

I take it you put 703's in?

 

For a 2000-01 it should be ford injectors thats what I put in mine they are out of a 3.8 ford windstar.

 

No, I believe they're the Bosch 784's...I'll have to look once I get my Jeep back from the shop.

 

Ah I didnt see the year of his xj

 

I'm pretty sure this is the list. Correct me if I'm wrong.
Dodge 703's for most XJ's
Dodge 784's for 97-99 XJ's
Ford's for 00-01 XJ's.

 

Here's the list:

 

I pulled injectors out of two 96 neons (like the chart says) at the yard and,
1: over payed for them,
2: they were the wrong ones!
They were 740s. So if you are pulling them yourself don't do what I did or you'll be kicking yourself like I am!

Hey! Let me know if you know anyone who want's 740s for their wifes neon!

 

Why won't the 740's work? I was told they were almost exactly like the 703's?
