Re: low boost, '96 900 - Saabnet.com Bulletin Board
The car has new 7ES plugs while the plug gap was checked. I bought a brand new DIC in conjunction with the hardware and software upgrades 7 years ago. Thus, the DIC has about 50k of use. Just to tease myself I also used my spare DIC to see if there is any change, none thus far.
At any rate, I connected the "W" hose and went our for another adaptation. Now, this is getting weird. Boost on WOT would touch the red zone then the gauge needle would back off. The APC valve that is on the car is one of the two working spares that I have, and, now, I'm thinking perhaps the APC valve that I have been using for the last 7 years is ok after all.
The only thing that changed in the last 7 years is the auto box which was replaced about two years ago. IIRC, about the same time that the car changed.
I haven't messed around with the base boost for the last 7 years. Perhaps, base boost changed. So, now, the ECU is thinking that boost is too high so its venting?
What about the MAP sensor? Do you know if those go bad?
