I was driving home tonight my phone rang so I pulled up and the car was probably idling for around 20 mins, i nipped into the garage for some fags and when i came out and started the car the EPC light came on and I had very little power as though the car was in limp mode i turned the car on and off and the fault cleared and the power came back, is this something to worry about or shall I just forget about it until it happens again? the car has got a neuspeed, precat delete and an rtech custom map. The car also got a clean bill of health from nick when he was mapping it and from stattlers when it had it's service recently.
