Question about 2000 Pontiac Grand Am GT
Code states "random multiple cylinder misfire detected" but I'm at a loss what more I need to do. I've replaced the fuel filter, fuel pump, changed spark plugs, coil housing, spark plug boots and it's still missing. I've checked the coil with an OHM meter and it was within specks.
Im surprised that didn't fix it. On the Quad4 engine its usually a cracked coil housing.
Have you checked:

I just had a simular problem. I didn't want to spend a lot of money I didn't have so I spent days trying things that were past due on the maintenance or required a lot of labor but little money. It turned out to be my first thought, ICM. I didn't want to trial and error this part @ $150.00. Then my friend suggested a junk yard. $40 bucks got me the whole ignition pack. I now have a coil tower housing, two coils and cover for spares and the problem is fixed for $40.00. Dont be afraid to buy these parts from the recycle yards.

Your problem maybe the crankshaft position sensor and the camshaft position sensor
