Edit- read more carefully. The discrepancy is still on the same side. Time to look for vacuum leaks, etc.

Ok to update still ahve the code cant find any problems at all. ONce the weather got cold i retrieved a P0300 code multi random misfire. Usally a Lean miss fire so im asuming im getting a lean miss which is caused by a vacuum leak between the A/F bank 1 sensor 1 and the MAF sensor?
