Engine problem
1999 Acura TL 6 cyl Four Wheel Drive Automatic 19752 miles
----------------------------------------------------------------
my mechanic fixed my car a couple of weeks ago he also had replaced one of my coils that had misfired but now its saying 5 coild have misfired!!! am so stressed about it as he said it couldnt be he is trying to find out if something else is wrong apart from that to set off the codes he got. WHAT should i do???

first of all, is the mileage right?less than 20k on a 9 year old car?
multiple misfires are not uncommon,sometimes even up to 5 cylinders.
how did he/you know that it was the coil that caused the misfire since the codes only tell you which cylinder misfires and not the cause.
also,the ignition control module wires are connected in a way that if one of them was not plugged in correctly,the other ones that follow it will not fire even if they are plugged.(series)
can you give me the codes and tell me which coil he replaced and any other information?
