Car shutting down

[Emilian]

I got a problem with the Supra and I cant figure out what it could be.

This is what the car is doing:
If I try and drive it, it wont go past 3,000 RPM. The car just "pops" really loud, almost as its misfiring.
If I drive it below 3,000RPM and push the clutch pedal, the RPM drops and the car shuts down.
If I sit and rev it, the car will shut off because the RPM drops.



Anybody know what the problem could be?

Sounds like an afm problem or large vac leak. Is the check engine light on, any codes?

 

[Emilian]

No, no check engine light.

I'll try and take a video and show you guys what happens.

 

[mkiiichip]

What was the last mod or repair? Or did you buy it like that?

The CEL may not be on, but pull codes anyway, there may be something helpful stored in the ecu.

 

[Emilian]

I bought the car like that.

Also is it turbo or na?

 

[Emilian]

Its a Turbo

I found out what the problem was. One of my 90 degree silicon couplers came loose off the intercooler and just needed to be reconnected. The car runs perfectly fine now! **Knock on wood**

i will check my intercooler pipes my car sounds just like that but I also have code 51 as well

Yeah, check and see. I talked to a few of my friends and they all told me to check my vacuum lines. I traced every vacuum line and it ended up being my intercooler silicon.
