Engine Mechanical problem
1993 Pontiac Grand Am 4 cyl Front Wheel Drive Automatic
replaced cylinder head and retimed the engine and engine lopes. In that year do the balance cam have a marking to set when I time the engine?

The timing is adjusted by the computer. The problem sounds like a bad idle air control valve (IAC) or a throttle position sensor (TPS). Has the check engine light come on?
