Default 99 misfire

Hi all, I have a 99 corvette with 67,000 miles on it. it has ported heads, cam, and long tubes. At the end of last summer and now the begining of this summer my car has developed a misfire while cruising between,
1800 and 2000 rpm, doesn't matter what gear or speed. spark plugs are clean and were replaced when the engine work was done about 15,000 miles ago, it also got new injectors at that time as well. I was thinking a
bad coil, can anyone confirm or suggest another diagnosis? thanks.

Pull codes, see if you have any misfire codes. Coils rarely go bad.
