hi thanks for that Paul as i said did not have a good look at the car due to time but hope to this week also not an expert but my main reason for the early post was the fact that i had high STFT and Zero LTFT which i would not expect and was trying to understand I understand that a vacum leak at idle would give a high STFT but i would have expected to see a high LTFT but perhaps im wrong

any way thanks for the reply will keep you informed when i get the car back and then post some more results may be get a better idea or maybe others could sujest what other tests i need to do brian
