yah i have the ecu for the si in my car. but heres what i did today. i left the car running and one at a time i pulled the plugs on the injectors to see if it lugged while on ewas off. my two inner ones lugged when they came off but my two outer ones stayed the same. so are my two outer ones bad or do they kick in when you give it gas and the two inner ones are used for idling?
