Starts fine sounds smooth. The minute it warms up it misses sputters stall dies. Have to double foot it to get it home. Let it cool off rand repeats all over again. I have replace all the sensors two new brains new cool packs new plugs and wires ran injector cleaner through it sea foam through it i'm ready to scream. One day it started acting up like this nothing traumatic happened to the car. Super frustrated. I read on a blog that where the computer is grounded under the coil packs sometimes the harness look like they are connected but here not getting enough connection they were all right. Any suggestions ? Help
