Can a GTEC 1 chip be affected by super unleaded - 14/10/2012 22:30
Hi all, yeap 12 days passed without any erractic idling issues, ie: when stationary reving at 700rpm, however just when i thought my horror idling issues have gone it came back and does the occasional 1500rpm when stationary or in slow moving traffic.
However now need to point this out, I put in super unleaded 98ron a couple of days ago, and an hour or two later the erractic idling came back!!!.
I strongly suspect the previous owner had a GTEC 1 chip fitted. Would I be right in thinking that the GTEC 1 chip is only suited to 95ron standard petrol, as when I put in super unleaded i'm back to my old erractic idling nightmare. I also suspect due to me putting in the super unleaded this confuses the ECU due to the GTEC 1 chip.
