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.

Thank you so much for your advise, I will certainly do the tests you suggest. Fingers crossed I will get somewhere with it this time. Cheers. Martin
