Default 4-hole Injector Swap Issues

Had nothing but problems with his MFn Jeep. New issue. Swapped out for 4-hole injectors and now listing P0172 and P0175 System too rich.
Wasn't expecting the feel of a turbo. But did hope for better gas mileage which is actually worse.

What injectors did you put in? I had the same issue when I first put Ford injectors in my '88 before putting Volvo's in to fix it.

I think they're from a Stratus. Popped right in. What part number should I be after?

I used the Denso fuel injectors part # 53030778 for my 96 XJ. The flow rate was perfect and I did feel a
difference in idle, pick up and a slight power increase. I haven't ran them long enough to get a good MPG
reading on them. The set was bought off of Ebay and they came with plug adaptors for the XJ. I believe
the Stock XJ plug ends were EV1's and these injuctors were EV6's I'm going to splice in new plug ends
in due to heat damage to the stock wires.

No but the same seller sells all the different injectors for all the different Cherokee. What I did is I took the serial number off of one of my stock injectors and cross-referenced it on his website. Or you can do what the previous poster said and get them from him.

Just ordered 784 Bosch' fj570 from eBay. Done with this ****. AND a Mopar TPS and MAP. sensor.
Gotta say....Just Empty Every Pocket. I'm getting something more reliable and putting this thing in the stable to practice my mechanical skills.
