Hey all!
I'm posting about my brothers 03 GT with about 150k miles. Here's whats going on... At around 4500 rpms it seems to be misfiring, and the service engine light will blink a few times, then goes off after the engine run at lower rmps and is not misfiring. Seems to lose a lot of power while trying to accelerate and shift into the next gear. We replaced plugs, and coil packs, but it seemed the car ran even worse. So we picked up wires. Replaced those, and now it will start up, but not running right, and when it goes into gear, it feels like its going to die. Sounds like a couple cylinders are not firing. Any help is appreciated! Thanks
