i recently had 2 change my v7 o2 sensor 1 bank 1 (pre turbo) all i had 2 do was get 1 that was 4 wire and grey plug, i think there is a different colour plug sensor aswell

cheers that sounds like a go

in the wairarapa, no check engine light and it doesnt seem 2 hesitate, just decides to run at 7psi instead of 15psi, exhaust note seems 2 change a bit when this happens which i assume is coz there not enuf boost 2 open wastegate

cheers 4 that, does the knock sensor not come up as a fault? just had the obd2 scan dun and nothing came up?

yeah, its really annoying, mine usually goes to 7psi just when i want the power e.g passing a evo lol and then clears when im just cruising, would like 2 sort it

def up to temp, still happens 2 hours into a long trip, possible shit fuel, i always run atleast 95 bt maybe its nt enough and mite have to run 98 all the time, i have heard of the wastegate actuator getting stuck on early wrx\'s but unsure if this could also be something to look at

Im running a standard v7 wrx apart from exhaust and i am having boost problems, it runs 15 psi normally then all of a sudden it decides to run 7 psi for a while then goes back to 15 psi, any reason for this? I have recently had to replace my afm and o2 sensor but this problem has been happening for the whole 3 years i\'ve owned the car, any ideas on the problem would be greatly appreciated, cheers
