I was taking off the connector to one of the injectors and I broke the plastic connector that's a part of the injector. Do I have to replace all the injectors or can I get away with just replacing the one I broke? I saw over on 4dsc that you have to be careful with ones that have black dots or something like that. What's everyones opinion on swapping out just one of the injectors.

 

You can do it no problem, Assuming you aren't paying someone to do it for you.
You have a VE motor so the Blue dot BS doesn't affect you. (or me)

 

Thanks for the info. I wish I would have seen your site before I bought the one I bought. I already see a few parts I'm interested in when I redo the suspension this summer.

 

Don't worry, there will be more stuff up there soon.

 

if you're going to change one...change them all while ur in there....

 

i have to agree with chris. out of a cost crunch, i did change only one - once. about three months went by, then another one started to go, then a couple worked partially. so it dawned on me to just change them all. i'm not going to take the intake off six times. forget that ****.

but, yes, you can change them one-by-one. have fun.

 

I agree with you guys. I'll do the other 5 down the road but I just spent close to $1000 on new sensors(just about all of them), gaskets, a clutch and a flywheel and didn't want to spend more. Car runs great now but I know the injectors need to be replaced in the next year or so.

 

how do you know if the injectors are bad? This has been suggested to me as the reason why my car is still having that hesitation hiccup thing. The dealer has replaced so many sensors already. They just did the coils and the problem is still there. If an injector is bad what are the symptoms?

 

Good question. Wish I had an answer. I have 180,000 miles on my car so I assume they are at the end of their life. I'll be interested in the replies to your question.

 

usually a dead cylinder, but also rough/inconsistent idle.
among other things

 

what internetautomar said; power dropping out, then on, then out; car runs like crap. sounds like a lawn mower. check plugs for fouling, bad gap, old.

with car off, get a volt/ohm meter thing and test the resistance of each injector: disconnect the harness from the injector and check between injector terminals. you should get about 10-14ohms. you can narrow down the field this way and see if it really is the injector or not. it could also be the harness connecting to the injector. overall, it is common after your car gets up in age to change all the injectors eventually. it is your destiny.

 

Sup All...

Injectors...those f*dj-ing things, boy I tell you. The quickest test to see if the injectors are bad is to pop the hood after its warm. One by one, pull the wires from the spark plugs, and take note of the ones that don't affect the idle. These would hint that those injectors are bad.

Conversely, if it does have an effect on the idle, then they are in working condition. Also, if the resistance is higher than around 15.1 ohms, (I think), then you know they are bad.

Hope that helps!

 

Why were you removing the injector harness? Were you just messing around one day?

If all you did was break the plastic connector, then I would get some tie wraps and ghetto rig that harness connector back on.

Now if the injector is actually dead and is causing you problems, then I would change that single one but do a resistance test on the rest of them to see if other ones are going out. If others ones are going out, then you can just replace those "out of spec" injectors. For ME, I don't mind working on my car to replace stupid injectors one at a time. But if you have to pay labor, then I would really think about replacing them all if you plan on keeping this car in the long run.

 

I didn't mess up the harness, I broke the plastic piece off of the injector itself. I bought a new one and I'm now up and running again. The car idles fine and all the other injectors seem to be ok spec-wise. I'll replace the other 5 when I start having issues. I know time-wise it would have been nice to replace all 6 but it wasn't too bad taking the intake plenum off. I've done more painful things.

 

So what plastic piece did you break? The pintle cap is plastic. If that breaks, you replace it and reinstall. There's no other plastic piece I can think of other than the harness connector on the injector.

 

I thought you were talking about the plastic (for a better term, female)connector that goes from the wiring harness and clicks on to the injector. I broke the (for a better term, male)connector on the injector itself. I think we are talking about the same plastic piece. I'm sure you're wondering how I broke that piece because it's a very hard plastic connector and all I can tell you is I did something stupid. I won't make the same stupid mistake I made again.

 

So the injector WAS NOT dead? That is what I was getting too. I bet you didn't break those two metal terminals on the injector itself, you just shattered the plastic male connector. Man, I would have found a way to ghetto fit that harness connector back on and be happy. Electrical tape, solder a jumper wire if you have to, or just use a few cable ties. I would have made it worked and saved a few pennies. I was really hoping you would answer my question before you did the job. Oh well. Your money.
