hi i just got an 86 rx7 and i am having problems. when i am driving and the car gets warmed up a coil pack shuts off so i replaced both of them and it is still doing it. floods and wont stay running and spits and sputters when i give it gas. so can some one help me .

 

How do you know the coil pack is shutting off?

Check to make sure the TPS sensor is plugged in and works.

 

When the car shuts off check the Black/Yellow wire at the leading coil for battery voltage and the Black/White wire at any of the emission solenoids that are part of the rat's nest located on the driver's side of the engine for battery voltage as well. Do not turn the key to off before measuring these two wires for voltage after the car dies.
