Trying to pinpoint leak HELP!!
So I had my sikky headers installed about 3 weeks ago by JE import. Since then they have been a constant hassle by installing a faulty O2 simulator which made me have to get in the car yet again drive to them an hour an a half away.
After another week I got CEL for a second time. After they fixed the faulty O2 sim....
Recently I have noticed a very strong fuel smell while driving. I understand you might get a fuel smell while at a light and the windows are down but I am experience one at crusing speed. I have gotten my car lifted three times in the past week to tighten the flanges connecting to the joeZ as well as checked for leaks (none were found) and there still is this strong smell
I do not want to install high flow cats.
I was wondering if anyone has had this issue?
I should not be getting a strong smell while moving at 60mph I am starting to think I have a leak at my cylinder heads due to a faulty install by JE.
Please help

The problem is I checked for leaks several times and tightened up the flanges. Which leads me to believe the leak might be even higher up near the header meeting the engine block. Yet again I have to waste another day at JE getting this sorted out.

I'm a Lexus master tech. I've heard of this before. We had a customer with an IS-F come in with brand new headers, and a check engine light with an A/F (02) sensor code. Turns out that there was a tiny pinhole leak where the header manufacturer welded in the A/F sensor bung. The A/F sensor was sensitive enough to pick up on this, and threw a code. I would hope that is also the cause of your gas smell.

I can also confirm what NotADood said....kinda/sorta off topic.
While my CEL was for a secondary O2, one of the high flow cats that was welded on my Borla had an extended O2 bung welded pretty ugly on it. Got the cats/bungs chopped off and voila, no more CEL.
Turns out one of the bungs had a teeny tiny pinhole-sized leak near the sensor, small enough to where I didn't notice any leaks or exhaust fume smells.
