Re: 3100 malibu random misfire?
my guess would be something fuel related like fuel injectors, fuel filter, FPR, etc.
check the coolant and make sure its not losing coolant, a bad headgasket could be leaking fluid into the cylinders and causing a misfire

At least check the fuel pressure and test the regulator. You will probably have to rig up the pressure tester so that you can view it while driving.2002 Silver Firebird A4<br />T-Tops, Leather, Y87, W68, Chrome Wheels<br />Bone Stock
