hi, I've had a problem with my 307, it was fine, but was then left stood for 7 weeks while my wife had an operation, when we came to start using it, it was lumpy and misfiring. I put it on a diagnostic machine I have and I came up cylinder 4 misfire, I changed the injectors (all off them), since then it has had a new coil pack and I've changed the crank sensor, and it's had new plugs. It's still running terrible, the codes I'm getting now are p0170 and p1336, and for some reason I also get a fault of misfire on cylinder 4, then that swaps to cylinder 2, and then back again. Can anybody offer any advice. Thanks everyone.
