well have had some issues lately, big ones!
firstly coming back from work it seemed lumpy and idle would drop very low and pick back up to around 900rpm then wouldnt start again after i got home, seems to be a fuel related issue.
after some advice from fellow tugboat owners i could see a few problems including the wrong airbox fitted and no MAF or air temp sensors connected up

maf i now have, no airbox though yet. have the air temp sensor courtesy of Khare (thanks agan

)
my original thinking was it had been disconnected to fool the management system as the old owner put a straight through pipe on in place of the cat. after further investigation the lambda is connected up properly (one thing i guess

) but as mentioned maf etc missing.
the other thing to note is the knock sensor cable is fraid and has exposed wiring so i will replace this straight away. do people think its worth looking at replacing the hall sender as this could also be a potential problem area and for around £12 its an easy fix?
