I wish I had mate but the label has worn off over time so I don't know it, it's the rs turbo fiesta, model year 1991... To be honest I'm happy to try anything at the minute abit of trial and error lol.. Car runs fine with out it but I'm fed up of having to keep revs on when parked up a lights with the fear of looking like a tit when it stalls haha
But Thankyou so much ill pm my mobile number
