So my expy was driving fine up until a few months ago when it started misfiring all of a sudden and i was at 207,*** miles or so so I figured it was overdue for the sparks being changed or something. Now I've got as far as changing all my plugs driving for a couple weeks with it still missing. Then I tried getting 'used' aftermarket coil packs but it was still randomly misfiring at times. not to bad so it didn't bother me much but then it started missing worse so I threw a code reader on it and it gave a p0301 p0306 and p0304 code so I went back to oh riellys and got 3 more new spark plugs cause I read a lot about dead spark plugs straight out the box. Well it was still misfiring so I started checking the resistance of my coil packs compared to the older ones and switching them out and was missing worse and worse and but it kept throwing a cylinder 3 code until one day I was driving down the freeway and it just started shaking and my check engine light started blinking and I lost all power down until I pulled off the freeway and checked under the hood and found that my coil pack for cylinder 3 had pretty much blown up. It was cracked and had some melted stuff that looked like plastic coming out the side of it. I replaced it with an old one and limp on what seemed to be for cylinders, to the O'Reilly's. Where I eventually left after buying new plugs and a couple coils and a coil plug connector. limped back to the house 15 miles away on what felt like four cylinders still And it not allowing me to go over like 20 or 30 miles an hour. After trying all the plugs making sure they were torqued down and testing the resistance on the rest of the coil packs, I again tried starting it with the same problem of it being in limp mode. I replace the plug connector, and all right tested surrounding cylinder spark plugs and coil packs with the faulting cylinder. and from what I know, I have 7 cylinders working it seems, but when I turn the key to on, I only have power to the one cylinder that doesn't fire when I actually start the vehicle. None of the rest of the coil packs appear to be getting any power before the vehicle turns on but they all fire correctly when I start the truck, I then tried buying brand new coil packs at O'Reilly's and a couple more plugs just in case there was another dead out the box, got h home and tested the brand new coils to the old ones that I believed to be functional , and found that they had the exact same resistance. So I then proceeded to clean all my fuel injectors on that side and put her all back together and she's still doing the same thing. Somebody told me it could my computer. I don't want to go around keep buying hundreds or thousands of dollars new car parts only to find that the problem is still there. Please help
