I like them. I guess i've noticed a bit better throttle response, but pretty much the same. Fuel economy went up a bit since they were clean vs my dirty azz stock injectors

Something not Covered?
Good write up, very informative! something I just thought about, while the injectors are out how do you clean up the ports on the heads? Just throttle body cleaner and a brush, but then all the gunk from around there is going into the head? Just a thought I had. Thanks

q-tips moistened with throttle body cleaner work well. A toothpick, a damp cloth, and a steady hand work well. Main point is you don't want any of the gunk going into the cylinder head. It's not that hard really.

^^^ This. I used a small flat blade screwdriver a little at a time until it was mostly cleaned out. You want to avoid getting anything in the cylinders at all costs.

Hey guys, please do not ask for injectors on this thread anymore. I will not be selling them anymore (or at least for quite some time). It's out of my control and I recommend that if you are looking for injectors to talk to Programbo on here. Stand up guy that does business very well.

Hey Matt!!!
Just wanted to say thanks for the P.M. and the explanation on why you are not selling the injectors no more... I totally understand.
But i did want to say thanks for all the great info you have posted up on this thread for all of us Cherokee owners, without this thread, i would have never had a clue i could up grade my injectors
Hope things work out with the junkyard for ya....
Good luck brother
