Engine misfires and won't revI have changed the plugs and the coils

Hello, At least you will have an extra set of coils. Really, don't throw them away. Smoke test the engine and accessory systems to find your vacuum leak. If you don't have one, you might have an issue with your cam and crankshaft position sensors, compression loss, a fuel deliver issue, or a PCM issue. Most of these issues can be identified through a diagnostic scanner.
