I to would start with codes. If you can't try cleaning the mas air flow sensor with maf cleaner or rubbing alcohol. Its located in the air intake tube . Remove it and clean the small wire that's in it with a small q tip swab be car full not to damage it

The last code was that the left bank was running lean. That was prior to the fuel filter and sensor being replaced. The SES light just came on again today and I haven't had it checked yet. Could it be the fuel pump?

A clogged fuel filter would cause both banks to go lean not just one also what sensor was replaced?We need to see what the actual code numbers you have now.Its P followed by a four digit number.You can check the actual fuel pressure but i would start with the codes first.
