Alright alright alright.....before you guys get all crusty and bash me by saying "use the search tool" or "this has already been discussed" I just want to ask

There are a series of Injectors on rock auto under the 2000 cherokee category that claim to be multi port. Would that me they are as good as say 784 neon Injectors?? I want to do something that will have the most direct swap. Without any manipulation. I was wondering if any one has tried the multi port Injectors
I even copied the name of the Injectors I'm talking about so you can see for yourself

{#4854181} Multi Port Injector

U could look up 97-99 dodge neon with 2.4L Engine for the 784 injectors

Fred/N0AZZ

784's 99 and up 4.0 XJ's.

XJwonders

he know that. He was asking if those injectors he looked up on RockAuto had multi port on the nozzles

Fred/N0AZZ

DOH! missed that part.

Yeah I'll do the Bosch 784s for $80 bucks if I have to but I see that the rock auto ones are probably built to specs and are half the price.

Just a quick aside, I upgraded the injectors on my 2001 last year. There are a set of injectors by Bosch that are single hole, but have a redesigned orafice, that will fit the Cherokee. The new orafice supposedly has better atomization than even 784's. So I tried them. They're for 99-03 v6 mustangs and a couple other vehicles. Just as a heads up, these fit in the rail but don't have clips like the stockers. I had issues with them leaking initially. I wouldn't suggest this route.

Okay good to know I've heard the 784 Injectors are plug and play if I do use them I'll go that route. I don't want to have splice wiring or anything weird.

CR-Snow

These were plug and play as far as wiring. But there are little clips that hold the stock injector into the rail so it seats properly. One thing i didn't do the first time that may have contributed to my leak was the petroleum jelly trick. Take a small bit and smear it on both o rings before you install the new ones. It helps keep a solid seal. I've been leak free since doing that move.

Another thing to note, I bought mine from eBay. And one of my injectors died about 2 weeks after I installed it. I'd buy from some place that has good customer service. And don't be a dummy like me and throw your old ones away. Keep them for trail spares or at least to use while you're waiting on a replacement if something goes wrong. Live and learn.

Okay I'll be sure to buy them new I am honestly going to try to rock auto ones.

No, they are not 4-hole injectors. "Multi-port" or "multi-point" means that you have multiple injectors, one (or more) for each cylinder. This is in contrast to throttle bottle injection (TBI), which is "single-point" because it has a single injector that sprays fuel into the throttle body. "Multi-port" does not refer to the number of holes in the injector.

All that product description is telling you is that this is an injector for use in a multi-point fuel injection system, and that it won't work in a throttle body injection system. If you search for pics of that product, you'll see that it has only one hole. It's not what you're looking for.

Got It I just ordered these suckers off Ebay. Honestly my jeep runs awesome great oil pressure quick start ups no burning coolant but my idle get a little low when she gets hot. I am going to switch out the fuel injectors, clean the TB clean the IAC replace injectors and get new spark plugs soon.

should I change out the O2 sensor when installing these guys? I guess it wouldn't hurt

CR-Snow

O2 sensors, kind of like Crank or cam sensors, are in my opinion "ain't broke don't fix it" parts. They're a pain to get to and so many faulty ones come through that it just doesn't make else. Sounds like your jeep runs good. Try to keep it that way
