Hello. Since a few of the other injector sale ads have slowed down I will jump in and sell a few sets of mine. I am selling sets of the common 703 and 784 4-hole "upgrade" injectors. The 4-hole spray pattern is an improvement over the stock Cherokee single hole injector and will give quicker starts, smoother idle, better throttle response and acceleration and in many cases a slight increase in MPG.
The injectors I am selling were degreased and disassembled by me then sent out to be professionally ultrasonically cleaned and reverse flushed. They were then rebuilt with all new o-rings, micro-filters and plastic pintle caps.
I am asking $80 a set shipped and can accept Paypal or a money order. If anyone wishes to rebuild some themselves I have some sets which have not gone through this cleaning process for $50 shipped. I will still degrease the outsides and test them electronically.

The majority of '98's used the old style injectors. They switched very late in the model year. If you have some sort of fat metal injector in there you'll need the 703's. The newer XJs use a round black plastic injector.

I bought a set of 746 injectors from Programbo and they are great, one of the best vendors I have dealt with. If you are on the fence and considering buying them, do it you won't regret it, and they are a great deal.
