I have run my 5 mode ECU IN MODE 1, am pulling a solid red and solid green, the car is warm, key in ON position. What does this combination mean exactly for MODE 1?

Also, for my EGR valve, & MAF, does anyone have recommendation on new vs. used? Where to find replacement parts above Advance Auto? These were kinda pricey, but I didn't think that I'd want to reuse one of these from a junkyard.. correct?

 

I think the codes are the same across the years I will check my 85 FSM and see what it says, as for the EGR and MAF as long as they test ok they should be fine, I have a EGR sitting around I think, I'll check and get back to you.

 

Here are some pics of my car...

 

yes I have a egr if needed, for your ecu, if thats with the key on, engine not running, selector counterclockwise, it's a bulb check they should be on. Yea I high azzed getting back to you was busy with my 200sx
