I received my new Bosch 703 injectors for my 98' XJ 4.0 and am very pleased with the results. The injectors were received very quickly and were well packed. Results were noticed immediately after install and resetting my PCM (idle improved significantly). I will wait to see if these improve MPG, but I am very happy with the product and service I received from JHC7399.
Finally installed my 784's yesterday for my 2001 XJ, (I have had them for a while, just waiting for right time.
You can tell a difference right away, and they look to be top notch quality.
I noticed the poster above me said he reset his ECM, is that recommended here if I changed these and plugs? I did notice the idle is a little lower than normal.

Yes you should. The new injectors will change the fuel trims. Resetting the computer will set it back to "learning mode" which will allow the computer to learn the new trims and set the air/fuel mix appropriately.
