Hi all, I'm having some misfire issues on my B7. More specifically, multiple misfires when the engine is warm. The engine runs perfectly when cold. It started about 3 months ago, I was having issues with a cylinder 7 misfire. I replaced the coil and all 8 plugs, that seemed to drastically reduce the problem. I would get a cylinder 7 misfire once in a while since then, about once every other week or so. I should note that this would only happen when the engine was warm and idling. Sitting at a stop light at a freeway off ramp would usually do the trick 9 times out of 10. A quick blip of the throttle would clear up the misfire and the car would run fine after. I was leaning towards a dying fuel injector as the cause. However, the other day the problem became much worse. It was an exceptionally hot day (about 35°c) and the car was misfiring badly; shaking, sputtering, rattling, the whole bit. When I got home I scanned the codes and found that I had a misfire on cylinders 5, 6, and 7. Here's where things could get interesting, I had the engine replaced about 6 months ago. The donor engine had the chain, guides, and tensioners replaced about 10,000kms before I bought it. Thus leading me to think that it would be unlikely for the timing chain to be the culprit, but I'm not ruling it out. Any ideas?
