I need to replace the alternator on my '97 grand caravan . I was told I need to know if it is a 90amp or 130amp. Does anyone know how to tell the difference. It has 119,000m w/ a 3.3lt engine & pw & pl.

There are a bunch of ways. Without explaining, when was the battery last replaced or charged? At night with the ac and lights on does the headlights dim(sorry I know I spelled that wrong) when you stop at a light? Just take it to an autozone and they will check it for free. If the idle has dropped below the normal 800 to 900 rpm then it might just be the pcv valve needs replacement.
