i've got a stick shift, but you'll be in the right area when u pull off the passenger side kick panel...see da ECU?
ok, then you'll see the control module above it!
did you also check the dropping resistor on the driver side fenderwall? as noted on the FAQs on

there's also a whole mess of trouble code scan u can do on the car before u start throwing parts @ it...
if u go near cherry hill NJ, I can let u borrow my FSM
