What should i look for when buying injectors? 1991 Q45. I was asked what month was the car made when trying to find how much injectors were at a junk yard. They said there are different injectors for the Q45. Dont know what i should look for.

What month? Sheesh. As far as I know all '90-'93 injectors are identical in design. The only difference is the color dot on each one, which I think only relates to spray pattern matching. I didn't think that mfg month had anything to do with the dot color, but could be.

Yes they were asking for the dot color and i dont know what it is. Another question about iac/aac... Where can i get another gasket so i can clean out my iac/aac?

Any dealership should have them. I normally order things from Joe, but for something that cheap I wouldn't bother if that's all you need. If you have a large order it'll definitely be worth waiting a few days for the $ you'll save.The dot color shouldn't matter too much for the injector. If you can get the same color as what's on your car now, great, if not, no biggie.
