Thanks for your interest, First there are no warning lights coming on when the engine is running that is no EML light or spanner light , I tried the pedal test that came up with I believe a code of 0230 if my counting is correct, I have connected a fault code reader that shows no fault codes, I have had the car several years so know it well, The first thing I noticed it seemed a bit flat then within a few days I only just managed to get it home worse than limp mode. now it will start tick over when you rev it will 2,500 to 3,000 revs then just die. I have changed the Crank sensor and Coil pack but it is no better. I think it is to good a car to scrap, I suppose that is my age. Car is 2002 Astra 1.6 8 valve, Thanks Richard
