Bad Coilpack?

[pacotaco345]

So I've been having this issue, never really thought much of it because its more annoying than anything else.. At idle or holding any rpm when not under load my SR will misfire. It makes it a PITA to time correctly, adjust idle correctly, sit in traffic like a normal person, etc. Once I put my foot to the floor or if I'm just cruising down the highway though the issue disappears. Oh, and this is gonna sound really stupid, but here's what it sounds like (bear with my onomatopoeia):

daaaaaaaaaaaaaaaaa da da daaaa da da da daaaaaaaaa da da daaaaaaa... etc.

Another issue, I don't know if it's related to this or not, is that under partial throttle (enough to get up over 4k rpm but under 60% throttle) the car will stutter but once again if I put my foot down it goes away. I've been told its a TPS issue but I've verified that my tps is good (sensor check through safc).

Please and thank you
