I've been monitoring my wide band for a few weeks now and my car been idle at 1100-1400. And my afr reads at 10.3-10.6 at idol. I smell gas at times with my top down when I stop at a red light. I believe I have a leak in my injectors. Might that be my problem ?
Please any experience or opinions would be great
So tired feeling every shop is out to get me.

You sure the tune is solid?

Already tried calling the tuner they said it's all normal -.-
And that they tuned with their sniffer for afr

10.6 is super rich at idle...

10s are rich. If you had one leaky injector you should be picking up a fluctuating afr since one cylinder is really rich and the others are "normal".

My guess is the tune needs some adjusting. What fuel and injectors are you running?

There is your problem. I had a tuner do this too and his "sniffer" was way off. He kept fattening it up and my guage would read pig rich and he said my guage was off and their sniffer was reliable. I bailed, car would barely run, flashed back to original tune and called it a $300 mistake.

Car should be idling around 14 ish

To determine the problem we need more information.

Was the car tuned and running fine and all of a sudden started to run rich? Or had you tuned it and then the problem with the rich idle came after that? How are you measuring your AFRs, if you have a gauge in the car why did the tuner decide to use his sniffer rather than your WBO2 (I'm assuming that you are running a wideband, if it isn't then you are almost better off guessing)?

If you do think that the injectors are leaking then take them out and get them tested.

Just to clarify, you smell raw gasoline or very rich exhaust?

What fuel, and what injectors do you have.

Big injectors are alot harder to idle low.

My ID2200's idle around 1000 and sit in the 11.4 range. I lean it out, and it coughs, and hiccups, drop it down, baby smooth.
