the same as the same engine in 1998 Intrigue:
The rating of the engine increased by 5hp in the following year for Pontiac:
The torque probably also increased, by 5lbf. In the above spec sheet the lower torque was reported , however this probably is error. See data for the year 2000:
In 1999 Intrigue gradually switched to new 3.5l engine, starting from higher trims. The base GX trim still had the same "leftower" engine as in 1998.
Probably, it did not make sense to bother with engineering changes for the short production run.
