I added headers recently and picked up a bit of low speed surge. didn't make a lot of sense with such a small change so I decided to log misfire info. Friday log showed Cyl 1 with a history and quite a few misfires. All other cylinders looked good.
I pulled #1, it looked good, I regapped and was another log today. Now Cyl 1 & 2 are showing a history and above avg misfires. Car pulls hard. Just low speed surge is irritating. Do not remember surge prior to headers. I though installer could have banged a plug up installing
Car is 07 Corvette LS7 with headers, original plugs, 11K miles.
