I just wanted to say. I should have bought a VE. I am so tired of messing around with these dang VG Injectors!
I've got some that OHM test good...but don't work. I've got one that has an OHM reading of 22 and works great.

I hate these injectors end of story!

 

loosen the purse strings and buy new OEM...problem solved.

 

lol

 

Not funny!

 

well then you're going to be plagued with these problems buying reman or used injectors.

i know it sucks to buy new since it's $$$..but for OEM at least you KNOW that once it's in you don't have to worry about them for another 80K-100K+.

i understand if there's no other solution or work around...but you have a solution available to you...but you just choose not to take it. so IMO you can't really complain..right?

 

I have an injector that seems not to work until warmed up. Does that make sense? Could it just be dirty? The car stumbles for a few minutes. I pulled one plug wire at a time, and found #4 didn't make a difference when it was in stumble mod, so I'm sure it's #4.

 

The story of my life: you got to pay to play...fixing it right can be expensive, but it is what needs to be done. Get yourself some new injectors and get rid of your headache.

 

I know my options...and I can complain because it doesnt make sense that an injector out of spec works fine, while one within spec doesnt. Maybe I am missing your point or something but mine is this.

VG Injectors have been some of the most inconsistent injectors I have ever delt with.

 

If you've got it narrowed down, replace it. Mine did that too before it finally went all the way. Then it sounded like a John Deere tractor.

 

Exactomundo...it is on its way out. Replace it.

 

agreed...the design are not the best...make sure your connectors are clean.

for the front set you can get a sub harness and it's plug and play. for the rear set you'll need to cut and splice.

 

You are SO right. Anyone who wants to play in the home mechanic game has got to pay (although less than at a paid mechanic). Moral of the story is, if you want to keep a 3rd gen on the road...and you want to be able to fix almost anything on these cars, you better have deep pockets or reserve money ready for repairs...to be done...the right way. Or else it'll just cost you more time and money in the end.

Pretty much most of the guys on this board aren't broke, they've spent thousands on their cars, but their thousands go a long way because they do it themselves. Now I see why you all say to do ALL the injectors at once with new OEM. It makes sense. At first I thought it was a waste of money, but it's not. I can imagine a world where the originals start to go out one by one month after month.

And doing repairs unexpectedly in the winter would not be fun.

 

To get the injector out, does just the upper manifold come off? Looks like there's a mid plate on top of the injectors?

 

yes the upper manifold comes off.

 

I also hate VG injectors. The idea "pay to play" is true, but doesn't apply to these terrible fuel injectors. Are we really supposed to drop $780 (for six injectors) every 120k miles for peace of mind? I replaced 3 injectors the beginning on the year with used ones off a parts car i had. I am pretty sure 1 or 2 more of them have died since. I have NEVER heard of any other cars eating injectors.

I am really confused/surprised/annoyed that all of you have that just pass off thousands on dollars spent on maintenance as "normal".
Don't get my wrong, I really like the car. It's quiet, smooth, comfortable and decently fast. But I only paid $1000 for it. There is no way I am paying that kind of money for something that should not have be a problem in the first place.
I will probably never buy a Nissan again

 

These VG injector issues are quite surprising to me. I thought VG's were the ones that were supposed to easily go 300k without skipping a beat?

Something I find odd is that, at least according to RockAuto, early 90's Sentra injectors are the same as the VE. So in addition to using 4th gens as means to pilfer VE injectors, I'll also start looking to Sentras

 

well injectors like anything else needs maintenance.
i ran my injectors past 140K with out any issues. I would use a cleaner in the rail and sprayed that through the injectors every 30-40K. i often change the gas filter every 10-15K.

so yeah if you never changed your filter or even serviced your injectors they are going to go on you.

you just paid $1000 for your maxima. i paid $23,000 back in 1990. so yes i've spent thousands and thousands of dollars on the car.

the car is old...so yeah a set of tires for the car might cost more than the car itself. people tend to cheap on parts and stuff just to get by. by doing that you run the risk of your car breaking down on you. you can't have it both ways. what happens when you need a timing belt? are you going to just get another maxima? the T-belt/wp/seals/etc job is around 500 bucks...so in your case that's half the price of the car.

it's not just nissans...ANY old car you're going to run into their problems.

 

What's the difference from injectors w/black marking and w/blue marking? I have a VG engine, don't have one out yet, and parts store has both.

 

I have never heard of injector maintenance, or "service".
I have spent my life around old, high mileage cars.
I have a 1987 toyota MR2 with almost 230k miles that is all original. Changed the clutch, some oil seals and that is it. In the Toyota world, when your engine finally wears out around 300k miles you clean your old injectors and throw them on the rebuilt motor.
My parents car is a '97 Honda accord, owned since new, with 276k miles on it. They do no maintenance what so every. It was a chore just to get them to buy a new alternator. They change their oil every 7500 miles, they have changed their trans fluid once. They even drove with toasted CV joints for about 6 years. NEVER REPLACED THE FUEL FILTER UNTIL A MONTH AGO. No injector problems.
My first car was a old ford escort. Family owned since new. Ran great till the day it was broad sided. 172k miles. Replaced the fuel filter once, Never did any injector maintenance. Funny thing is I broke a t-belt, while driving. Threw on a new belt. Non-interference motor. Everybody does it except nissan.
I have never used any OEM parts in any of my cars

 

why did you buy a maxima?

toyota 1MZ, 3MZ, etc are all interference motors.
Honda J30 motors and i believe all their motors (if not most) are interference.
Audi ATW, AWE motors are all interference.

this is first hand knowledge since i've either owned these or family own these cars/motor that i work on.

yup...only nissan

your car...i could care less what you put in it. op complained about reman injectors.

 

Reman injectors? Where did you pull that from?

 

newer Ford, mazda, hyundai, subarus (95 on up) all interference. Virtually any newer car that uses a t-belt is interference. it's just the side effect of one way to more horsepower.

 

So, does "new" injectors mean only Bosch? or are the JECS injectors on eBay any good? I've heard the Python ones are crap, but it would be nice to save a little money .

 

sorry about that...
i mean bad injectors (over all design?)

 

IMO if they are new and made by a decent company they should be ok.
the reman and rebuilt stuff is where people get in trouble. pythons are reman.

 

Can anyone explain the blue vs black marking on injectors?

 

Its in bad taste to come on here and brag about how much you enjoy NEGLECTING vehicles. Its doesn't flatter said vehicles or yourself, please spare us.

 

the OEM superseded them to one part #. I believe that blue was eliminated to leave only black IIRC

 

people also tend to ignore the fact that a high mileage car will have fewer issues than a low mileage car. when a car is run for longer periods of time continuously it tends to burn the contaminants out of the oil, the moisture out of the exhaust and the water out of the brake system. it also means the car continuously has fresh fuel which means it won't gum up the injectors quickly either.

 

I never said I neglect nor enjoy neglecting my vehicles, my parents do, but i do not. So don't put words in my mouth, that is truly in bad taste.
I could of taken better care of my escort, but being a kid at the time and first car ya know.

These injectors burn out their coils, not gum up. You can actually fix gummed up injectors.

 

Like when you see an ad like "1989 car, 100k miles. Thats only 5k a year!"

Yippee, 100k miles of jump starts and cold-running!

 

do you realize why their coils burn out?
