I bought this car last week from an individual and drove it home about 60 miles. Been driving for a few days with no issues till these codes popped up. Still runs fine just has the codes. Mods are 706 heads and a hot cam, shift kit and cat back.

P0102 maf low frequency
P0174 bank 2 lean
P0300 random misfire

The misfire could be a simple tune up but I'm unsure of the other 2. Any help will be greatly appreciated

K&N filter? Maybe the guy cleaned it for you before you picked it up and over oiled it. Even if it's not, the first thing I'd do is clean the MAF. You can get a can of MAF cleaner for like $10 at Advance, etc.

A dirty MAF will throw codes...sometimes...and random misfires are also a symptom of a dirty MAF...
