I was wondering if this create problems or interference?



Let's say I disconnect the CAS and check codes... blah bla blah. The check engine light is supposed to flash X-amount of times. While in my case you turn the power on, the engine light turns off then comes on and stays on.. Anybody ever experience this?

I guess swapping the ECU is fine as long as it's in the same series (S5NA to S5NA). I'm still having problems with pulling codes, I can't find anything on this..

probly, I disconnected a solenoid and still nothing. I'm gonna try swapping out another ecu. If the ECU comes from an AT would it throw a code?
