I have a 1994 NA Miata which was turboed about 7 months ago everything was professionally done but a performance company in my area.
for about 2 months now i have not driven the Miata because of an idle issue i have been having which both scares me on the road and shuts off my car sometimes aswell.
i have recently checked for vacuum leaks (none) cleaned the throttle body which as a result did nothing again. i have mega squirt in the car, if learning mega squirt is the best thing to do here to really hit the pin on the head here i will read the forum on that and get to it.
i uploaded a video maybe one of you have had the same issue with idle. anything would help thank you in advance. i just found out about this forum site and i will definitely be lurking around here because i really do love Miata's and im curious to see how all of your builds are going.
this is a picture
there is also a video of what is going on in the attachments below

 

There’s an idle adjustment screw on the throttle body. Have you checked that? One extreme is too fast of an idle and the other is no or too little air at no throttle condition, aka idle,

 

If you have an MS, I would highly recommend learning to use it. You'll love your car even more once you understand why it does what it does.

Learning to tune idle (looks like your issue) is a great safe place to start and there's tons of documentation on this forum to teach you everything you need. You'll just need a laptop, tunerstudio software, and a serial cable. Just for the love of god please search and read before creating a thread on something already discussed (everything), or choosing to experiment with retarded spark-cut rev limiter while testing out a special sauce 100kpa fuel map. Or do... just keep the camera rolling for us!

Welcome to the forum though, I've been mostly lurking for 2 years and can't explain how much I've learned (and spent) from being on here

EDIT: @adam holy batman, just realized we have the same stats

 

im in tech school at the moment but we dont deal with anything tuning wise so tomorrow i will bring my laptop outside and check whats going on with MS ill do my research tonight from here and i will check it all out :P thank you

 

i will definitely check that out tomorrow i have seen some videos on that tiny thing ill get into that car tomorrow and really grind on trying to fix it.
