Hey, I've got a 16v sri and its fitted with one of those air pumps that blows air into the exhaust on start up. Its started playing up latly, either not working or turning off and on randomly. Can any1 tell me if it can be removed without messing up other stuff and if so if there anything i need to do that isnt obvious. cheers.
P.s. its the secondary air pump im on about.
