I was wondering if anyone knew if my vehicle was obd1 or 2 or if there was a way to find out. Its a 00 gsr bottemend with a pr3 -4 type r head (not sure of the year)

 

take a picture of the ECU.

 

What part of the car are we talking about, engine, engine harness, cabin harness, ecu, or the car itself?

 

engine wise. I am looking at getting a new idle control valve and distributor and water temp sensor and i need to make sure i have the right one. I think it is obo2 since i heard that if the idle control valve has 3 wires going into it its obo2. but not sure.

 

anyone?

 

found out myself it was obd1. Thanks everyone!!
