Ok, I need to adjust my idle, but my Z doesn't have an idle adjusting screw, so how am I supposed to adjust the idle on these cars?
I've read my Haynes book and it points to using the idle adjusting screw. I've looked all over and there's no adjusting screw.

 

I took a picture of what I'm looking at:

Ok, here's the link to the picture: http://nomoredata.com/280zx/Engine%2...ure%20145.html


I can't find the stupid idle adjusting screw or is there another way of adjusting the idle?

 

picture no workie for me, but did you ever remove anything from the intake mani, should definatly have the screw if you didn.t

 

No, I didn't remove anything, but weird thing is that even my parts ZX doesn't have it.

Here's a link to the picture.

 

Can you take a pic of the engine bay a lil more zoomed out??? Piecing pics together isn't too fun.

From this pic it looks like the idle screw is just to the right of the TPS:

 

dido ^^^^ looks like its right there 2 copper tubes are in the way though so cant tell for sure

 

This may be a better picture, but yeah...I see no idle screw, ugh

 

Negatory... click on the attached pic

 

Wow, I could've never guessed that!

So, I had advanced the timing a bit (to help the engine idle better); after finding the idle adjusting screw, I left the timing back the way it was from before.

I opened the idle adjusting screw (the one circled in the picture) almost all the way out, but the car seems to have lost some power, so I advanced the timing a bit more; it runs and idles better.

Now I notice that the car idles at around 500-550 RPM, but checking Hayens...it says that it should idle 700 +/- 50 RPM for a '82 non-turbo manual transmission.

Any suggestions or ideas?

 

vacume leak?

 

Did you just replace your distributor? You shouldn't have to adjust the idle screw on an FI, unless it's in extreme situations.

 

Well, I replaced the distributor cap and rotor, but as for the whole distributor assembly...nope, haven't replaced that.

 

I checked for vacuum leaks and I'm pretty sure I have none.
