Go to ths site. It says you can not change the timimg on a 97 astro. as of now I am looking to do that to mine since it keeps misfiring. It states that the computer does the timing work. So if the ditributor cap is on wrong that causes it to misfire.http://www.justanswer.com/questions/27r9v-1997-chevy-astro-van-check
You need to disconnect the timing plug for the computer, then time it to zero degrees. Once you plug the timing plug back in, the computer will self time the motor from there.
