can i delete my iac?
I'm running a megasquirt diypnp I can't bring down the idle. So Phil suggests a look as the iac I found that the air valve on the throttle body is stuck open. I think this is my problem. Is their a way to stop the iac from doing this and just use the idle screw to a adjust my idle. Please help

Are you sure its stuck open or is MS keeping it open. What does Megasquirt show that the Idle duty cycle is?
|
you want to delete a very important part of the idle control system because you're too cheap/lazy to actually fix the part that's not working right?
....or is this a race car and you don't care about cold starts and idle stability? |
l2t.

It's not that I'm to cheap I can't get the part right know and I need my car for the weekend. I'm still in the process of ilde tuning. And I with the air valve stuck open it won't go below 2700 rpm. This is tetemporary. Till I can get my hands on the part. Is their any easy way around this for now. So I can move my car?

If it's temporary then sure.

ait =/= iacv
so you still need to try what he is telling you |
You can probably get it unstuck with an old toothbrush and some carb cleaner.

how did you find that it was stuck open?
how did you determine is was mechanically stuck open and not just told to stay open? |
telepathy

I took it off and checked it then heated with a heat gun to see if it moves I'm not just guesing . as all-data says to do. And it does not move

I'm not confused with the thermostat. Though this part works just like a themostat . the part I'm talking about is connected the the intake manifold. With 2 hoses that go to the thermostat. The heat from the antifreeze opens this air valve like a thermostat would. And let's air past the throttle blade. As shown here http://www.justanswer.com/car/2p5e2-...rol-valve.html

I'm new to tuning . not Car I've been an auto Tec for 6 years professionaly I still have stuff to learn , but I'm not confused. Maybe im confusing when I type or somthing. I'm just looking for away around this temporarily.

This is a better diagram to see how it would effect idle . https://www.google.com/search?q=does+a+93+miata+have+an+iac%3F&source=lnm s&tbm=isch&sa=X&ei=S8BcVcahEae_sQTFi4HgCg&ved=0CAs Q_AUoAA&biw=360&bih=517#tbm=isch&q=93+miata+iac+ai r+valve&imgrc=sf8UN-qPVJIa1M%253A%3BJh4qkr8taUDb4M%3Bhttp%253A%252F%25 2Fwww.miata.net%252Fgarage%252Fisc_files%252Fimage 002.jpg%3Bhttp%253A%252F%252Fwww.miata.net%252Fgar age%252Fisc.html%3B568%3B524

he's talking about the stupid air valve on the IM. if that was stuck open your idle would not be stuck at 2700rpm.
go ahead and block it forever. |
