cylinder miss

so.....back in the summer my 2005 Tacoma crew cab was doin a little buckin and jumpin. So I replaced all the spark plugs. It was fine for about 250 miles when it started again only this time the engine light came on. After pluggin it up, it said cylinder 6 was missing. I immediately thought it was the ignition coil so I put a new one in. After I drove it for about 100 miles, the light went off and it seemed fine. Another 150 miles later, it started again so I had the transmission fluid drained and refilled. I then drove it and about 10 miles into the drive the engine light started blinking and eventually became solid and stayed on. I plugged it up again and this time it said that cylinders 1,5, and 6 were missing. Has anyone had this problem, and if so what did you do? I am now going to go home today and take out the spark plugs to make sure they have the correct gap, if it still does it then I was thinking about looking at the fuel filter. A little advice would be greatly appreciated.

I would read thru the following thread and pay heed to the comment made by a veteran tech in post #8. Never mind that's it's not a Tacoma thread. Coils are coils.

Did you use an OEM coil? A lot of after-market coils go bad as soon as you install them.

Not sure I follow the transmission fluid change.
