runs very rough, flashjing "service engine soon" light, when driving. goes away when idling

Sounds like the Cylinder #2 is misfiring. There are several things that can cause that problem, the most common ones are the Ignition Coil and spark plug. I suggest starting by replacing the spark plug. Do you have any other codes?
-
If you have the P0300, then it is possible that you have more than one cylinder misfiring. I recommend starting by replacing all the spark plugs and if possible use high octane fuel for a couple of weeks to clean the fuel injectors.
-
Already did all of that and I've been running premium for a month now. I replaced plugs coils, bank 1 and 2 IVT solenoids, both camshaft sensors, the MAF, all 4 oxygen sensors,
-
The front IVT Solenoid had a bent metal gasket when I replaced it and it leaked all over the number 2 coil and spark plug. I'm going to remove and swap that coil with another to see if it changes the misfire to #4 , but I don't have time until Thursday
-
When I checked the coil it was loose and covered in oil. I cleaned it and tightened it, and the code disappeared. It runs much better now, but now I'm getting the P2A03 and P2A00 codes, but I've already replaced all 4 O2 sensors! I was also getting a P0444 code, but I cleaned out the Purge solenoid, reset the codes, and so far (only drove 30 miles so far) the P0444 hasn't come back and the "Service Engine Soon" light hasn't come back on, the Cat is "OK", but the O2 sensor is "INC". EVAP is also INC on my code reader... but I suspect the Service Engine Soon light and maybe the P0444 code will come back on and INC Soon. Oh, and I replaced the gas cap with a brand new one...
-
Hopefully the oxygen sensor codes will not come back, it may take some time for the ECM to calibrate after cleaning and tighten the loose coil.
About the P0444, check for any loose connection, you may have left a loose connector when the plugs and coils were replaced.P0444 2007 Nissan Maxima Code - EVAP Canister Purge Volume Control Solenoid Valve Circuit Open
