Welcome to hell!

Your best bet is to get some silicone hoses, and replace the standard vac hoses, is your best starting point.

hi, thanx for the reply changed all vac hoses, n75 valve, the other 2 valves at top of engine, pre cat lamba sen. lamba sen was previous fault code but now gone. do u think coolant temp sen or maf sen could be the cause of the fault? cheers.
