Hey, I was on the highway when I noticed my car sounding different and had no acceleration so I took it to a shop. They said I had a misfire on cylinder 6 so we switched the coils to see if it followed the coil or stayed with the cylinder and it followed the coil. I got a new coil and it fixed the problem but as soon as I exited the driveway cylinder 5 went out. Changed it and got back on the road then cylinder 1, 3 went out so now I got frustrated and got the 4 remaining coils and 6 new plugs. I took the car for a spin, plug thecomputer into it and it said it was all good to to. Now just my lucky, 30 min down the road another one goes! I have changed all the coil packs and spark plugs so what could it be? It like they are being shorted out. Thanks for the help.
