I checked the butterfly valve and it moved etc. But not checked the actual motor. So waiting for new VIS motor to arrive. Slowly ruling things out. |

So it appears after a compression test one of the cylinders is half what it should be which is what is causing the misfire. Possible a leaky/burnt/bent valve. Looks like I'll be dismantling this engine to try and fix it

A couple of months ago I had a KV6 that wouldn't start, history was that the car had been stood for about 3 months. The owner had tried everything. When I looked at the car and tried to start it it turned over as if all the plugs had been removed. There was no compression at all. After numerous attempts to start the engine it would give an occasional slight hiccup. It had a full charge in the battery so I thought I'd do something I don't like doing I turned it over on the key continuously for a good 40-50 seconds The engine spluttered and then roared into life, result What had happened was that while the car was stood the tappets had lost their oil, turning over the engine sufficiently built up the oil pressure which refilled the tappets enabling the car to start. Not saying this is the cause but it can be a possibility Russ

I am having a slightly similar problem. Occasionally when I start the engine from cold the engine fault light comes on. Misfire on cylinder 2 is detected. If I clear the fault with my Autel gadget the fault clears and everything is perfect until the next cold start. Although sometimes I can have several cold starts without the light coming on. I have changed the plug and the coil on that cylinder. Yesterday I replaced the injector. The new injector looks differrent from the one I took out see photos. I was sure I had found the culprit but no, this morning the cylinder 2 misfire fault came back. I am hoping that the plug may be fouled (if the injector was faulty) and it will either clear itself or a new plug will do the trick.
