Non matching plugs Right now I've got 7 NGK Tr-55 plugs and one of the stock AC-Delco plugs in my car(don't ask why). Napa has to special order the NGK plugs so they won't be here for a few days. Is it bad for my car to drive it the way it is right now? It seems like it's running fine, it's not misifiring or anything.

Let me take a guess. you couldn't get to # 8? I ran 7 ngk's and on ac delco for a while and everything was fine 
(because i couldn't get to #8)
I had to have a more nimble friend get it.

7 tr55's here....1 tr55 iridium...
I couldn't get to #8 the first time I installed plugs and I lost the TR55 plug I would have put in there...so I got the bright idea to go with 1 iridium and put it in when i did my headers, which was simple compared to when I attempted the switch the first time without a lift...so that's the reason for my mismatch
but no problems drive your car with no worries because if the plugs got you around before they should continue to do so until you get the last one switched out
