hello everyone!
bought 2 x5s this month
1 is a 2006 v8 with no issues !!
the other is a clean 2003 3.0 with a p1343 code
(misfire cylinder 1 with fuel cut off) and very rough running until i unplug the maf then i get full power restored and drives like a dream with a slight rough idle. also with the maf unplugged the p1343 is gone and replaced with the P0102 (maf circuit low)...
so far I've only changed plugs swapped coils(misfire stays with cyl 1)


has anyone ever experienced this or better yet solved a similar situation?
thanks.
