What is the correct idle speed for a 1996 Bonneville SSEi supercharged engine. Mine is (approx.) 1100 rpm's at cold start up and 700rpm when warmed up in park, fluctuating around 500 or 600 in gear. No check engine light is on, doesn't stall and otherwise seems to run fine! My 1997 Bonneville SE non supercharged engine is about 1500rpm cold start up and 800 to 900 warm in gear. The SSEi seems low to me, but this is my first supercharged engine model and I'm not sure! If it is, how can this be corrected?

Seems about right. Low end torque FTW

Yeah that sounds about right. I usually see my LeSabre sit around 650-700 in gear warm, and about 750-800 in park. Depending on how warm it is, I've seen it closer to the 500s in the summer heat.

Thanks for the responses! Finding out this is pretty much correct for this engine!
