i think i'm getting too much boost
Hi. New here. I have a '94 SSEi that I got at 100k miles, now at 142k. It seems from what I have read that I am getting too much boost. The gauge reads +1 or so at idle +2 with a/c on. It jumps to 5 or more when i touch the gas, and it maxes out at 1/2 throttle or so. At idle, the rod in the BCA is almost fully extended, down by the supercharger bolt. Removing the top vac hose extends it just a bit more. removing the bottom brings it all the way up. In either position, I see no change in the boost reading at the gauge. Could this be the BCS?
I also have a SES light, only once the engine is hot and when I let off of the gas. Once on, it stays on, with a p1640 code, or so I'm told. (don't know if the boost is related to the light but it might be a clue).
