timing

You cant! it's controlled automatically by the computer! if it gets out of limits you will get a fault code! ( correlation bewteen camshaft & crankshaft fault) and if that happens it's most likey distributor gear or timing chain! it's cheaper to just buy a new distributor around $80! the gear alone is $50! Warning!!! if you change the distributor you have to know what your doing!!! if it does not go back in the exact same place and your off a tooth left or right you Jimmy will not run right! and you get a nice code to tell you that!!!!!
