2000 Corolla 1.6, had it serviced thursday at F1 Autocentre. I noticed later that the engine management light was on. I took it back to them & they cleared it (can't remember how). The light came back on last night & I was also getting some pinking under load, which I was getting sometimes before the service. When doing the service could they have knocked something causing the light to come on, or could this have been a problem in waiting? I don't think F1 have the kit to plug into the car's computer, as they only do basic servicing/tyres/exhausts etc. I have got it booked into the Toyota dealer, monday for them to hook up & see what the error is. Any ideas?
TIA
