    Start with the basic. Make sure you are getting fuel, spark and timing is correct. Report back with your findings.

    What spark plugs did you buy? Brand and type.
    What did you gap them to?

    Have you done a boost leak test?
    Are there any exhaust leaks?
    Any check engine light codes?

    Why dont you upload a picture of your engine bay, it will help us a lot faster.

    Fill out a profile. Be more specific. Did this start happening after you did something?

    I just bought the car at first it had a idleing issues were it wouldnt stay running but u could drive it and everything shifted fine and runs good no knocks or ticks or anything just when u dont have ur foot on the gas the car basically just dies. Thr car has 108,788 miles on it. Ian did bot modification to it myself and looks like all the guy i bought it from has did to its is a air intake besides that nothing else that u can tell.

    Man she needs some serious love, but there's nothing we seek more than a stockish DSM.

    I can guarantee you have a few boost leaks. Make a boost leak tester. These cars run like sh** with even small vacuum leaks.
    Besides the obvious you want to check the TPS (throttle position sensor), if it's not calibrated properly it will cause many issues including your symptoms. Also the IAC motor (idle air control valve or ISC) which goes bad on these cars, specifically the tan ones.
    I'm thinking your problem lies within the throttle body.
    Really what you need to do is clean and rebuid that throttle body and make sure the sensors attached to it are working properly. The TPS is a bi*** to adjust the first time you do it but it has to be done right

    Bov not hooked up, spark plug wires “numbered” wrong, just by observing the photo. Check biss isnt bottomed out. Previous owner did more than just intake. That is aftermarket turbo, 1g cas which means he did some wiring, 1g head etc.

    I would double check your spark plug firing order. Since you have a 1g cas you have to swap the plug wires.

    Easiest way to say it, on the coil pack it should be stamped, it looks like he has your coilpack just sitting upside down, so make sure its oriented correctly, but factory is 4-1-2-3. All you have to do is swap the coils, so i move them together to get my new firing order 2-3-4-1. Been doing it that way for 20 years, never had an issue. Others have other firing orders that work, but thats how i do mine. That is of course if thats the issue. Cylinder number one is the one closest to timing belt.

    The ground wire for your battery, looks like it has no nut on the stud.

    This may not be your problem, but after watching your video it sounds like a problem I recently had with the power transistor. My car started once, idled rough and only stayed running while I had my foot on the gas. After that it wouldn't start and was flooding. You could diagnose this if you have spark on 2 cylinders and not the other 2. On my 6 bolt the power tr unit is located on the back of the head on the driver side near the timing belt cover. I was lucky and the plug had just wiggled loose. Again not sure if this is your issue but thought I'd throw this out there. Others have posted good possibilities as well. Ill include a pic of what it is. Good luck!

    What did you end up doing to get it running? And after watching the new video it acts like vacuum leaks or vac lines not ran properly. Someone above mentioned that the bov wasn't hooked up, there may be others not ran or not ran correctly
