Ok as you all probably know, I just replaced my knock sensor and a bad injector. I got the vacume leak fixed (turns out it was bad o rings on the fuel rail) Now everything runs good, but befor when I had the leak it triped some codes, one being o2 sensor. I drove the car around and the light went off. But now I have smoke comming from my tail pipe and it smells like raw gas. Any ideas?

 

Sounds like you still have a o ring leaking...

 

The o rings that where leaking whernt the ones on the injector. It was the ones that seals the fuel rail onto the intake. So they didnt actually have anything to do with gas. And i didnt touch any of the injectors, just the new one and i put new o rings on that one

 

You may have pinched the o ring when you installed the new injector into the rail....This happens alot....

 

But why would it of just gone bad now, i drove it yesterday and a little today without this issue. wierd

Well looks like you right man. Put in a new o2 sensor and still the issue. The old one was pretty beat and had a dent in it anyway. But i pulled all the plugs and the plug on the cyliner I put the new injector in was wet and smelled like gas. Go figure. Looks like thats tomorrows job. THanks for all the insight tho

I do have one more question. When installing the smaller o ring. the one on the bottom of the injector. Does it sit at the bottom of the hole that the injector sits in or does it get installed on tjhe injector?

 

It goes on the injector

 

Ok thats what I thought, I bet its because I used the old o-ring. I couldent find the new one. Found it today, rolled under my bed
