[QUOTE="04forcefed, post: 14836223, member: 149674"] So just like the title says I just got Kooks LTs installed and unfortunately the installer didn't reuse the stock gaskets and the headers leak a small amount on the passenger side. But when I tuned the car I had no codes than all of a sudden at idle my CEL came on. So I hooked up my tuner and I got the passenger side throwing system to lean code. I dataloged my car and at idle LTFT1 sits at 1.25 and LTFT2 sits at 1.17 STFT1 & 2 sit at .95 and .93 respectively. Under throttle all read +/- .05 of 1.00. LTFT1 & 2 both start to rise again under deceleration. I will be changing my gaskets when I get the new oem ones and hoping that fixes the problem. I've tightened my air intake and made sure that there is no area where air can leak. What else could the issue be? [/QUOTE]
