hi people, i have a 04 vectra 2.2dti estate and have had the dreaded spanner light. the fault showing on it is the throttle body. i have already taken it off along with the egr valve and cleaned them. my question is this. before i have to get into the expense of buying a new throttle body, i would like to check all the hoses, can some1 point me in the direction of a "how to" or explain how many hoses and the best way to go about it, do the hoses have to come off for a proper inspection. sorry for rambling, i hope u guys know wot i need exactly. thanks.
