I collected the caravan from Horsham, delivered it to West End (just off J3 M3) then back to Heathrow, got home at 9.20, had some dinner, spent an hour or so the my forums then off to bed, back at work for 6.00 this morning.
Tonight I replaced a leakoff pipe and removed an electric fuel pump that I was hoping might fix my problem (just in case it was air ingress) but didn't help.
I then swapped the MAP sensors and after a very short drive it shows no sign of improvement.
Should any faults have been cleared before it will recognize the new sensor ?
I'll give it a proper run tomorrow and see what it's like just in case.
On a side note my central locking has stopped locking from the key, it'll unlock but not lock.
