on the passenger side of the engine bay, againt the firewall there is a small tank (white) in my 88 s4 n/a and i was wondering what i should put in it. there is a pump on it and a hose witch runs into the intake manifold; gas or what goes into this tank?

this is a cold start assist resovoir. it would normally have anti-freeze in it and on cold day it would inject anti-freeze into the intake manifold. Mazda had a TSB on this and discontinued it. you should disconnect it and remove it. also if you want you can remove the injector. Banzaitoyota sells a block off plate for it

im not positive but i think 88 was the last year they used this. i removed mine from my 88. i dont see what the point is of injecting anti-freeze into the intake is. how in the hell does that help with cold-starts? one would think injecting a non-flamable liquid into the engine would impede starting.

Well, it was something that Mazda used for quite a while, since my '73 RX-2 had it also.
