Hi guys, new to this forum. I bought this V8 6 months ago with a misfire problem. After a major service, timing set and thousands spent (4000 in pounds, listed below) and allot of crap from so-called mechanics, the misfire is gone but the car now keeps cutting out randomly. It starts and idles for a few seconds then cuts out and also cuts out (with massive backfires) unexpectantly while driving. The car also has no power and sometimes only when I floor the pedal. The last diagnostic test showed the crank position sensor and we had to reprogram the keys. That's it, the problem persists. I love this car but I,m sick of it. I thought of destroying it. please help guys, surely there must be someone that had the same experience !!!!
