So I swapped out my stock injectors with bosch 4 hole 703 I found on ebay paid 205 shipped to the door which is a whole lot cheaper the precision injectors took about 25min start to finish to swap fired right up a whole lot faster than before and just purrs like a kitten now idle now near perfect smooth as ever just filled the jeep up so will see how mpgs do soon but as far as power improvement of course its not like a threw a supercharger on it but a for sure improvement across the board over stock more responsive and just an over all more efficient filling out of the motor good upgrade!!

 

There is a guy on here that has 703's for $80 shipped he is in the for sale section can't remember his user name

 

I got mine for free.

 

x2 at the jy.

 

Awesome free is always good

 

205?! ouch... I got mine from NO RDPLZ here on the site. Something like 60 or 70 shipped to my door. BUT the upgrade is a good one as I did it to my 00 and noticed a decent improvement in acceleration and over all response in the throttle.

 

Damn u got a good deal but ya im very happy with the swap too

 

I swapped the stock injectors with the 703's. Seat of the pants tells me I did good.

The 88 XJ stock injectors had 126M on them and looked like they were coated with a varnish when I removed them.

 

Same here mine had 170k on them looked like they set in a bucket of crude oil for a year huge improvement

 

I thought my idle was better. Then I figured out the truck just idles better after a PCM reset, eventually goes back to the same.

MPG does not seem better either. I'm about to take one hell of a road trip so I will know for sure later.

The engine does seem to have more midrange though.
