Misfiring/Rough Run

Don't know if this will help anyone but thought it worth posting since it cost me $500. 96 Bird 3.8 v6 110k miles.... She started skipping and misfiring, running like 5hit. Read the codes: P? MAF or MAV sensor no output, P? Multiple Cylinder Misfire. Figured I'd replace the MAF and be done w/ this, MAF probably causing misfires. $150 @ autozone later, back to square 1. :banghead: Figured a fuel filter and drygas would not hurt, still running like crap. $265 @ the shop for a #2 cyl coilpack and new #2 sparkplug (fouled due to misfire) Runs tip top again. Out $500 for a $40 part...
