low voltage maf code and half working boost gauge?

I recently installed a set of eBay headers on my 00 gtp. That went well for awhile but now the car is giving me low voltage maf code, this is after having replacing it since the other one died. The car idles kinda up and down but not tooo bad. It does die every once in awhile if I let off the gas and hit the brakes. The boost gauge only reads half with my foot to the floor, it's pulling hard but could this be a vacuum leak or something?
 


check for vac leaks. also check the fuse box for a blown fuse, # 26 iirc. and the wires to the maf, check them for damage.
 
Thanks for the help. Any good way to check if the wires are o.k. still? Like could I use a volt/ohm meter? Or a continuity* tester. I know the fuel rails are a place for a vacuum leak pretty easy. Any other common place?
 
follow the plastic hard lines around the engine, they make a loop basically. fpr, under the snout, the bbv, the evap from the TB. all over.

not sure the volts at the pig tails. there are threads with that info. if you see missing insulation or cracks in the wires, theres no need to check the volts, the wires are bad.
