P0300 random misfire
on my 99 tahoe 4wd ( about 150k miles), my engine light went on and got this code, also a couple weeks ago, it was saying bank 1 to rich..
spark plug are only a couple months old.
what could cause the misfire? ( before changing the plugs I also had the random misfire code show up then went away as I changed the plugs)
