IIRC all LeSabre's that year were 3800's.

What is the VIN? The 8th digit is the engine.

I have seen references in parts books of the TPI engine in 91, but has anyone ever SEEN one in a 1991 car?



91 had the 3.8 with the addition of Tuned Port Injection to make 170hp, only the '86 had the 3.0 as standard.
