84 is weak. HELP

[hamer]

i recently bought an 84 GN. It runs pretty damn good. But when i get on it and the dummy lights come on she doesnt have the umph i think it should. Leak somewhere? boost too low?

You should start by getting a boost guage at the very least. The second idiot light comes on at only 7psi on my dad's car. A scan tool is highly recommended so you know all sensors are working and 02 volts are within the right range.

Ummm, which "dummy" lights come on??? Do you have the digital dash??? etc...

We will need some more info to be able to help you better....
