To fix the timing on a 1990 Pontiac Grand Prix LE with a 3.1L V6 engine, first ensure the engine is at TDC (Top Dead Center) on the compression stroke for cylinder #1. Then, check the timing mark on the harmonic balancer against the timing tab on the engine; it should align with the specified degree (usually around 0 degrees). If it doesn't, loosen the distributor hold-down bolt and rotate the distributor slightly until the marks align. Finally, tighten the distributor bolt and recheck the timing to ensure it's set correctly.
