2004 Chevy Cavalier 2.2L-P0302
Have an '04 Cavalier w/2.2L eng. Engine has a noticeable missfire after driving and engine warms. When this happens (misfire), check engine light illuminates & begins to shift strangely. Have had scanned and found a P0302 code. Replaced wires/coil boots & plugs. Had rescanned & found p0300, P0302, P0201 & P0202. The P0300 codes are misfire codes & the P200 codes are injector circuit codes. The P0200 codes came up once, were cleared and have not come back since. Injectors have been tested w/ noid light & ohms checked & do not appear to have a problem. Any clues as to what I should check next?

Were the spark plugs the correct gap? What brand were the wires, were the boot long enough to slip and click over the spark plugs?
