Now that I have the misfire fixed, I've got one other problem to deal with. Check engine light came back on and I pulled a P0172 code (system too rich, left bank). So I'm guessing either o2 sensor or fuel injector. it's running a bit rough, ran some of that injector cleaner through didn't make much of a difference. I take it to the shop next weekend since I'll be off duty, but I was just wondering what y'all think. Y'all know what you're talking about so this is the first place I come when I have an issue with my camaro.

Thanks in advance

could be alot of things but the o2 sensor is a good start as many people claim that they should be swapped for routine mantiance, especailly if you are getting up in the miles... other things that come to mind are the usual air/fuel, depending on the year of your car you may have a sensor that if is dirty will not the proper amount of air flow ( think it is MAF?) I had this problem on a 2000 3.8 Grand Prix but you could defintely tell something was up with the idel before it threw the code - broke down in the mall of millena on me thing there is a way to clean the sensor but not 100% sure.

geuss the question that comes is there any change in performance, idel, mpg etc.?? to present as before the issue

good luck

I had just cured the misfire problem but it was still running rough. There's a little hesitation and mileage has dropped down to about 25-27 or so. Usually most of the hesitation comes when i have the throttle barely in but when i start to go over 35% throttle it smooths out some. Another thing it does is when I'm cruising and I start to slow down, when i push in the clutch it drops to 500-600 RPM and sometimes bounces back up to normal idle (around 800-900 RPM) and sometimes doesn't climb back up to normal till i get close to a complete stop. I can't think of any other relevant info but if I think of anything I'll let you know.
