Multiple cylinder misfire Question..

Hi, My friend has a 96 camaro RS.. It started running like hell the other day and i scanned it with autotap and I got a code for low MAF frequency and egr pintle position.. The EGR code was on before this problem happened.. So we replaced the MAF after I checked the wiring and harness. The car immediately started misfiring on random cylinders. Anyone else had this happen before? Please help!

When I got the "multiple cylinder misfire", it ended up being a bad ground.

....found that out after plugs, wires, and a coil pack.

check to make sure that your wires didn't get sliced by a pulley or something, I got the p0401 when my PS pump chewed on the wires, but mines a V8 so IDK.
