Q: 03 pontiac vibe getting misfire codes random and all 4 cylinders previously before some repairs it was cylinder 1 and 4 or 1 and

I started getting a check engine light with codes P0300, p0301, P0304 I replace the spark plugs I still had a rough idle it's hesitating when I accelerate at low RPMs low gears like there's a loss of power or an issue shifting but not every single time I change the coils I change the MAF sensor I changed the alternator I was getting a high reading on the battery and the manual said that would have been one of the first things to change I change the drive belt I'm still having a bad drive at low RPMs and acceleration but when I get to higher RPMs above 2000 and above second or third gear I have no problems driving which leads me to believe it's not a fuel issue maybe an O2 sensor hopefully not the catalytic converter or a tranny solenoid but I'm not sure took it into Pep Boys they were no help no smells that are obvious no leaks that are obvious I was told them I might have a minor valve leak last time I took it in possibly a valve cap I haven't seen it myself
