Hey guys this is a follow on form my last post. I am a new GQ owner and i have had a few problems and im some what sure that a vac leek is the root cause of them as you will see from the pics mine is missing the stock part called air ducting. Affter calling Nissan and 6 wreckers i have come to the concultion my only real option is to make something or adapt something. option 1 would be get a pice of the 45 bend intercooler piping from autobarn or somewhere and put 2 of thoses things for the airlines OR i see on ebay you can by that bit for a gu and im a sure ISH it would work. My GQ is going to see a machenic thursday i will check that this is the problem but i would be sure it is. When I plugged the hole it seamed to run better. And when i removed the plug eg my finger is whisteld. In a way i would like to make something i will keep you posted see pics bellow. any tips comments or problems i have missed please do tell
