piston misfire =bad spark plug IAC valve is one part
Fuel injection spider unit if it's mpi. Fuel pressure regulator and relief valve also.
Of if it's Sefi. Sorry as the intake has to come off but sometimes you can take throttle body off and look on hole using a mirror while they turn key to on/not run position and see if the pressure valve on the spider unit is leaking fuel. That is a bad thing.
