What is the problem with a 1997 Grand Am GT if it taps when first started and smoothes out after the car run for a while?

What you are hearing is the lifters tapping. Lack of oil

changes, using poor quality of oil,wrong viscosity, and dirty oil

filters will cause this. The engine bearings may be getting worn as

well.

Change your oil regularly with good quality products, add in

some oil treatment like Lucas oil stabilizer to help keep things

lubricated after the oil has drained down to the pan, that way the

tapping at start up will diminish or go away entirely.
