Looking for some advice. Took my car for a drive after sitting since the shootout. Car warmed up in my driveway. It’s been warmed up once before without issues. After being warmed up, I drove it. After about 2 miles of 35-40 mph driving, my car dropped cylinders 2/3. They came back in for about 45 more seconds before they went out completely. I pulled over and tried to restart the car. During cranking, all four would fire and the car would come alive, then immediately drop the same 2/3 coil again.
I brought it home, verified spark on 2/3 only happens during cranking and maybe a split second after. The car throws an 044 ignition circuit malfunction CEL. Once it’s out of startup, they drop again. so from there, I swapped coils (both ohmed out well), CAS, PTU, dynatek, tach box all one at a time to look for any difference. It acted the same way the whole time. I also verified grounds since I have all external components come to a common ground connected directly to the battery. Tried a different battery too. Weirdly, the dynatek status led illuminates when key on and cranking, but shuts off after startup as well. I've also noticed the car runs on all four just a little bit longer when I let it sit for a little bit. What am I missing ladies and gents? Any help is greatly appreciated. Sorry for the long post but I figured the more info the better. I will be testing/measuring all of my spare electrical parts tomorrow to verify the swapped parts were any good.
