No, the 3100's didn't come in until '95. My intake header says "3.1 LITER MFI" cut right into the aluminum. It matches the engine in the car it replaced, which was a '92 Grand Prix SE.

The transmission on it is the 4T60-E (according to the tranny pan under the car).

It does have a 2-stage catalytic converter on the Euro model, but single exhaust - means I have 2 little cats (kittens?) instead of one large one. Only one O2 sensor though, go figure.

Didn't get a chance to test engine-off, in-gear at lunch.
