po172, and po175....
could this be caused by bad spark plugs? I also know my maf has been reading low, but i had the maf tables readjusted to bring the readings more into line. Any suggestions?

P0172 and P0175 are fuel trims rich, banks 1 & 2. Spark plugs won't do that.
If you know your MAF is reading low or is modified in any way, then the MAF needs to be re-calibrated.

can the problem be fixed with VE tuning?
