I know it's on here a thousand different times, but the search function on my phone app doesn't show me anything. I need new injectors, and I was going to buy new ones. I'm having problems finding the part number for the neon upgrade. I have a 93 with a 4.0 auto if it makes a difference. Can somebody PLEASE give me a part number so I can go to autozone and pick some up? I can't handle only getting 150 miles to a tank of gas much longer

703 injectors i believe

Yeah I need more info though, like what yr/engine combo I need to find

I would suggest pulling them from a Junkyard and cleaning them, rebuilding them with new o-rings, filters and pintle caps and then flow testing them. Doing all that would be cheaper than buying them brand new from the auto part store.

what make you so sure its the injectors?

there are certainly several other things that can cause poor mileage, what else have you tried?

also been suggested to google "fuel mileage"

for what its worth i have over 313,000 miles on original injectors and get about 280 miles out of a tank on the highway not great but better than what you are dealing with

ArmyGraham

I've done all the basics, but no change. If nothing else because of the better mist that the neon injectors have, should increase mpg. I'll probably sea foam it too

Yea i saw a company that sells full sets of flow matched injectors. They are on youtube. They show the difference between stock and four hole injectors. stock ones are like a squirt gun. And the bosch are like fog machines. I also seafoamed it. two cans. Big difference

150 miles per tank!? Are you sure you don't have something else wrong with your rig?

motorcharge

This. New theyre $70-80 per injector.

That company i was talking about sells a set of 6 flow matched four hole for $170. Dont bother getting them one at a time

precisionautoinjectors.com has good stuff if you don't want to go the JY route.

As far as your mileage, I'm going to assume you're lifted on big tires with stock gears, yes? That would be a major part of your problem. And are you filling up a full 20 gallons or close to that after 150 miles? Your fuel level sending unit may be faulty.

ArmyGraham

Yes I am, on 32s but had just slightly better before lift

ArmyGraham

And yes, your probably right

ArmyGraham

Usually around 15 gals I think. Are you sure it's a 20 gallon tank in 93?
