Just wondering about my injectors. I had some 1.8 inj laying around and don't really know if the are dirty and flowing 100%

I am now running the Greddy with these 1.8's.

Lets say that hypothetically one of them is partially clogged or whatever. Will the WB show an issue like this or a similar one?

Thanks

 

A WB only gives you a picture of the overall AFR in the motor. If you have one leaky injector your motor might show a little lean when you were tuning. You would have increased fuel to make up for it. So in effect you would have 3 rich cylinders and 1 lean one. Classic failure.

You would have to have a wb on each cylinder to really tell.

Could you give more information on what is occuring to make you think this might be happening?

 

Thanks Neogenesis,

I don't really think there is a problem, I am probably just being paranoid. But I am just a bit concerned as these 1.8 inj came from my old car that had about 260000kms on it. Now that I am boosting I really hope that they are all flowing at 100%
I am debating to soak my old 1.6 inj in carb cleaner or seafoam or something else for a couple days and then take the 1.8s out and do the same with them.

Any ideas on cleaning my own injectors?

Thanks again

 

for the low price and peace of mind, I'd send 'm out to get cleaned...

 

what the O2 will show you is that if you're running closed loop with a leaky injector, your AFRs might be close to correct but the car will run like ****

 

A dirty injector will usually show up as a misfire, if you install them.
