What ECU are you using?

 

I really have no clue, I will have to check tomorrow. arg..

 

I have a car but ummm I don't know what it has, hummmmmmmmmmm :slap: :db:

 

Easy dude, the dude who works on my car said its what I needed so he ordered it, I bought it, and he installed it. I will check what it is tomorrow. Chill

 

so you have a 99 SI with an OBD0 B16a? :thinking:

It will probibly be the P28 or the P2T ECU in there.
the P28 is the commonly known and used OBD1 ECU, can be chipped to run anything.
the P2T came in the 99-00 SI and is OBD2b.

Note: the codes pulled from the car, have to matched to the ECU vintage.
Also OBD2 and OBD2b can be plugged into be a code scanner and a more acurate code can be pulled.

 

I got it fixed today, it was infact the primary o2 sensor, it was getting bad response or something, but got it worked out, thanks
