My car is missing on cylinders 4 and 5 primarily.. NEED HELP! Car ran 100% as of Sunday, driving to change spark plugs. Put new plugs in and gapped them correctly, same plugs i've already had in the car.. Threaded plugs in by finger, and then tightened about a quarter of a turn or so.. Driving back, once the car was warmed up, NOT WHEN IT WAS COLD really, it started missing a little.. and from a stop, 1st and 2nd it would stutter until about 2500rpms.. Last night I replaced the spark plug wires, except #8, which im changing today with the help of a lift.
Scanned the car and its primarily missing on 4 and 5. But it shows that the other cylinders except 1 and 8 have just a few misses in the log we took. I made sure over and over that the spark plug wires were connected, and they seem to BE connected. But its still missing.
Talked to a friend a few minutes ago that said to switch up wires 4 and 5 with the wires before them and see if it moves the miss to those cylinders, which would mean its faulty wires.. If it doesnt move, its the plugs..
What do yall think?

a while ago one of mine was missing after a set of new plugs and i replaced the wire and it was fixed...another solution might be the ignition coil ive heard those too can go bad once in a while and cause your engine to miss

Like z28oc91 said, if the plugs/wires doesn't fix the problem, try swapping the coils around and see if the problem still stays with cylinders 4 & 5.
Good luck!!
