Hi All
Went to start my 740 yesterday as soon as I turned the key I got a massive backfire. It then started and revved itself up a bit before dying. I've had it running since but it won't idle at all and is still running rough and backfiring. I can hear what sounds like an air leak from around the inlet manifold but spraying WD on it was inconclusive as the engine was hot enough to start burning it off straight away. I nipped up all the manifold nuts but this didn't help. The car drove great when I last used it on Saturday. The only thing out of the ordinary was that I had to boot it pretty hard in 1st and 2nd after I pulled out of a junction and seen someone coming at full beans. Even after this it ran fine until parked up.
Any advice much appreciated.
