Okay, here goes....was out driving yesterday and the car went into limp home mode with revs not exceeding 3000rpm. I drove the car to my mate's garage where he connected it to a launch machine and no codes were present on the ECU.
Restarted the car and was able to rev up to 3750 revs whilst stationary which i think is the safety limit whilst stood still.
My mate suggested that the ECU could have picked up an unbalanced pulse and kicked in to limp home mode.
Drove the car home with no problems...was able to hit 4k revs no problems and was able to get good speeds but the car was very unresponsive at low speeds.
In other words, you put your foot down and it takes a good few seconds to respond etc.
At first, I thought MAS sensors but surely, the ECU would kick into safe mode again ? This has not happened as I am able to get it up to speed...eventually !
I did fill up at tesco two days ago and the tank had about a quarter of a tank...could this be low quality fuel ? I always fill up at tesco with no previous problems etc....
Please help
Thanks
