Please help me I have tried everything. I have been having problems since early summer.

My car has weird symptoms. Right now the main one is it's missing/breaking up at wot starting around 3500 rpm. It sounds like its popping and backfiring a little as it does this.

Sometimes It has has a hard time accelerating under part throttle when it does it sounds like it's bogging down.

Then sometimes it just completely dies when at wot and won't start again until I cycle the key off then back on.

The only codes I get is for several coil pack failures.

This what I have replaced.

all 8 coil packs
fuel pumps
alternator
battery
spark plugs
fuel filter
tried different maf
repaired connector at crank sensor because of bare wire.

I'm tempted to replace the chip with a tuner. I think it could be computer related. Plus I could data log.
