Hi. A couple of months ago, when driving off from waiting at the lights for a while, there seemed to be just about no power and I had to limp for a few hundred yards until there was a cloud of exhaust and all returned to normal. I don't think any warning lights came on. On Monday a similar thing happened: I left the engine running for a few minutes - maybe 2 - and then there was no power, and the ECP light came on orange. I limped a couple of hundred yards and put the car into reverse to go home. Again there was a cloud of exhaust and all returned to normal. I haven't driven the car since, but need to know what is going on - any ideas?
