Gentleman, some of you already know me around the site, that being said I like to solve before starting pointless threads like so many new members. But I feel I could use of your assistance.
From one day to the next, I started to bog out around 7psi 3500rpm give it take. I search around tested the common causes. No luck so far.
Please let's get passed the boost leak , some may immediately jump too. I have to many years of boost leaks so it's not that.
So far I replaced plugs and wires.
I tested the power transistor and got continuity in all cylinders.
.
I also took pics of my ECU, I don't see anything that sticks out, so I posted pics so you guys can help me check, sometimes capacitors are the cause.
ECU LAST SERVICES BY ECM IN 2009/2010.
now, I also tested my cool pack at room temp, and unpluged I came in at around 15-16kohms. And plugged in at around 1.3-1.5ohms which is out of speed according to the manual.
Also I snaked my fuel pressure gauge close to the wind shield to see if it's fuel cut and it doesn't appear so, I base this on the fact that the pressure climbs as the boost climbs which is expected.
So I'm looking for guidance. I know it will be hard as few DSM guys really get this technical with diagnosing. So any help is good.
