I have the engine from a 93 Bonneville SSEI , I do not have a map sensor. I have looked throught the wiring diagrams and do not see anything mentioned. The car runs great it is just I bought another engine and it had a map sensor. DId some if the 3800sc'* in 93 not have a map sensor?

I don't think any of the pre-'96 3800s had MAP sensors.

Actually on the supercharged model there is a MAP sensor, however I'm pretty sure the PCM doesn't use it. It'* for the boost gauge.

thing is I have 2 93 3800sc engines 1 is in my car one i just got , the one in the car does not have map sensor. The one i just picked up does have map sensor..
