Well I just purchased my 87 n/a and I was looking over the engine. There are a lot of plugs that lead to nothing but i think its because the car was orginally a T2 but for some reason the owner switched it to N/a. Well I was looking over the car and I noticed that the plug that goes into the stock headers which I am assuming is the O2 sensor is plugged into the header but the other end is just hanging and is not plugged in. There is about 1-2 feet of wire between the two ends and I cannot find where it plugs into. If anyone knows which I am sure you do please let me know. Also my 5/6th actuators are stuck closed I think they will not open when revving it, also they will not open by hand even when i press hard. There is a nipple at the bottom of them and by the diagrams I have seen there is supposed to be a air line there but I dont know where it connects to. Please help me to get this baby running well. Thanks and sorry for the long post.

 

i'm with you too, no one ever worked on my car besides the guy i got it from and me.



so many plugs that arent plugged to anything kind of make you think mazda got bored and decided to try to play a hide go seek with wires
