a boost leak.

Check your codes.

 

[Fletch124]

Exhaust leak.

 

[a70Derek]

Yes, uh, yes you do.

[a70Derek]

really.
well i do have a toyota supra 1987 7MGTE
where's the code reader?

 

[Big Wang Bandit]

Right fuckinghere

Jeeze

 

[a70Derek]

alright.
im follow the website given.
thanks guys!
this should work.

 

[a70Derek]

the engine check light went away, but still not boosting.

 

[s383mmber1]

Do you have a turbo?

Hehehe

Does your turbo spin freely? Excessive shaft play?

Have you checked your exhaust system? Boost leaks?

Try being a little more descritive, as your posts are short, and could be just about anything!

You're joking...........right?

 

[Fletch124]

Could you please explain exactly what is happening?

*example*My car wont boost WOT even at 5K, boost gauge works in vacuum but boosting it just sits at 0*example*.

 

[a70Derek]

the problem is my boost guage is old and it's not functioning right.
i need to replave the guage.

more than likely the line for the boost gauge popped off, check the lines going across the firewall to the back of the intake manifold and to the sensor.

Is it at the bottom of the gauge when the key is off? Does it go to 0 and stay there when the car is on? If so, then you need to check the vaccuum lines (they also have boost through em, so if you replaced them, they pop off really easy...use zip ties)
