LH0 is the RPO code for the 3.1 mpfi engine. All 3.1's in thirdgens(and most other gm cars) are LH0's

naft is correct, but I'll extend it more.
Every option on your car has a code, which is what the RPO is. LH0, LB8, LB9, B4C, IC5, F41, etc... I'm guessing about 100 or more codes, all 3 long.
The RPO for the 3.1 is LH0, not LHO.
View this thread about halfway down, and you will find more specs on the v6 engines in these cars.
