Hi all. LOL, months down line and still the same. Prob not rubbish in tank, as 'surely' that would affect cold performance? Anyhow, I just ordered 4 used injectors PLUS rail combined for 50 quid incl VAT delivered. Bargain I spotted. Comes off of a car with 40k, just written off, no prior eng probs. I am now looking back to injector....maybe when I had 'em sonically cleaned they ripped me off-who knows. Car still misses when driven on MWay after 10 miles or so. No orange light after changing 02 sensor BTW.Losing lots coolant now, but have just checked and radiator seems to be made of paper ma
