Recently got a check engine light, and traction control light on the dash of my 05 with the LS3 swap. I got the code P0207. I’m planing on changing the spark plug on cyl. #7 and the O-rings on the others. Is this suffice or is it needed for all the injectors time be changed??
So, how many miles does your current fuel injectors have on them ?
just under 40,000 miles.
I need to correct myself... I changed all the spark plugs and wires and now plan to either CLEAN each injector with a little more attention to the 7th cylinder injector. And install new o-rings

Had one go bad on my C5. Never worked right until I replaced them all. But I used Bosch refurbished ones and saved a good bit of $$ and they never went bad. Lasted at least 7 years, probably more.
