Very good, detailed instructions. One thing that helped me is I ran the jeep and pulled the relay for the fuel pump, and it relived all of that pressure.
I had heat soak on the #3 inj for several months. Tried to jury rig some insulation, but no dice. Decided to go with 4 hole injectors used but cleaned and tested from K Suspension, and the DE heat shield kit. I found that the throttle response seemed more immediate and precise, but maybe that's because they are clean and fresh? Your presentation of the procedure was very clear.
I thought about it but I've heard stories about computer getting confused and I'm about to go on a 4000 mile trip so I didn't want any surprises. But they certainly might be in the future
@@officialWWM Better atomization of the fuel which reportedly gives better throttle response, better idle. Possibly better MPG. There's a video by "injector rehab" (put that + "jeep" in the search) which shows exactly what it does. Cheers
@@MajorWeakness I did go with the 4 port injectors, my PCM went haywire. I had multiple codes thrown P0172, along with the 0300 multiple misfires codes, and both O2 sensors went bad. I fixed everything new O2 sensors, and bought 4 port injectors from K suspension, it fixed the issues I had. The PCM issue I had was with the cheap Chinese made 4 port injectors I bought off eBay were bad. Lesson learned, don’t buy cheap Chinese injectors, they are either a hit or miss. Everything is working fine on my 99 XJ now, no more codes.
Outstanding job man, well made video, cut all the bs out and leave only the informative stuff. I think I’m subscribed to your channel already if not Im going to 👌🏼🤘🏼
Noticeable change yes. Completely eliminated heat soak no. I've since learned that if your fuel pump is old the check valve is weak allowing pressure to fall while off. This allowing vapor lock on startup of a warm engine. I changed fuel pump on one of. My XJs and problem solved
It's designed for 97-04 jeep 4.0 engines only. The same company might have some universal wrapping material you can use. Go to their website and check out

Great tip

Nice job Major.Suprised you didn't go with a 4 hole upgraded fuel injector.💪👍👍

What are the benefits?

Good stuff man, just installed mine and this made it much easier
I'm glad it helped
Nice, I’ll be installing mine tomorrow. Don’t know if you noticed but that first injector you removed and showed up close was cracked
Yes a few were cracked
Excellent video, lots of good information. Will be doing my injections soon... It's totally time. And the heat shielding is an excellent idea.
Thank you. Seems to be running fine so far!
Congrats on reaching 2,000 my friend
Thank you!

Neon injector plugs fit and are built better,.
Good tip
Thanks for your video, how has the heat shield been working, any noticeable change? Thanks again.

Could you put the injector covers on before you install them back on the engine?
No because you would not have access to the electrical plugs
i didnt see how you put them on over the connector? looks like its not easy
After making this video it seems the Duralast is now a better value. Either way they were the same unit as of the making of this video
Will this fit a 93 xj
