My Engine Warning Light has Started to come on causing rough running and idle, I am given to understand that this could be caused by the O2 sensor & the ECU being faulty, If this is the case what is their location on the car that I may change them.. 1987 MK11 Turbo Supra.. Thanks and I will Wait For a Reply

O2 sensor is bolted right into the elbow behind the turbo
ecu is behind glove box . it would help if you pull the codes the engine light is recording heres how i would check the two (vsv) valves on the intake side uder the intake one is for fuel one is for EGR both are vacuum switches you might have a diagram of these 2 switches on the underside of the hood you might want to check out these service manual pages EFI troubleshooting diagnostic if it's a california car there more O2 sensors
