Nothing wrong here, we all will jump on a deal and see what we can get out of things on the low cost end. but it seems that you need a little extra love to get this as a DD

Good Start here on the simple things that look to be from a known working donor car. When you changed the coil pack, did you also take the wires or are they new?

Put used cold air intake on off of parts car. Never drove anywhere, just sat up and ran occasionally. Started sputtering and skipping, it cleared up. It sat another 8 months,

Drive 1x to work a week to stop battery loss and general "Sitting Up" this is a good rule for any vehicle that you have. Dont let it sit for extended periods because that is where bad things begin.

just started driving as a daily driver. Has rough idle and stutters and sputters bad under load. Shows misfire on #6 code, and 1233 code for fuel pump module and maf code for voltage. Will continue to run diag with snap on scanner. Anyone had similar problems with one that's been sitting up for a while?

Swap the Plug wire at both ends #5 and #6 then recheck it. If the misfire has moved to #5 then its the wires. Its not a perfect test but its a beginning.

Name the rats or evict them. Pull a Part for new wire harness or just make your own its not that hard in the end.
