Idles perfect, but dies after a couple seconds, or when throttle pressed?
So I drove my turbo Miata (MS2 1993 1.6) to work last week, and I’m getting ready to leave, and the car starts, but is unable to move. The Miata will idle perfectly at 1,300 rpm, but it will die if I press the throttle. It would also have 3 symptoms of idling. Either idle for exactly 15 seconds and die, idle for 2-3 minutes and die, or not even idle and crank up and die. And anytime I press the gas at all, it will die, revs won’t even build up. The car ran fine before hand, and didn’t have any issues. I have also noticed the AFR gauge is reading in just accessory mode, and reads ~14.5 but after a couple of seconds, it will spike up passed 18 and be unreadable. Some advice would be much appreciated!

Is it possible that your TPS wires are loose or perhaps your throttle cable (seems unlikely.) So it doesn't even rev up if the clutch is out in neutral and you press the throttle? Does it go lean when you press the throttle?

Funny story, I just bought the Miata about 3 months ago right after moving, so I decided to make my first bad financial decisions as a 18 year old. So it was turboed and tuned by the previous owner, so after owning my stock miata for a while, I decided to learn turbo stuff. Long story short, I have yet to have a laptop to hook up to the MS2. The car has been turboed for a full year now with no issues. But I’ll definitely look into that hose, and a possible corruption.
