Gave the car a run tonight, first time since fitting the Thor speed delimiter (there was nothing there before so must have imagined going over 120 in the past)
Anyway, got to around 60mph and the engine management light came on, stopped at the bank as that's where I was heading, restarted car, and all alright, then on the way back, EML on, then the O/D light started flashing, crawled home.
Guessing it's the SLD I've fitted, brought it second hand, but as working. Could it be this, or something else perhaps??
I've followed the fitting instructions as posted by DB on here.
Any thoughts??
