sup guys,

my friends car is messed up has a eg not to sure what year but..

the only way he is able to drive his car is when he presses down on the brake

and when we lets go of the brake his car dies..


hopefully we can find out whats wrong, we are both saying electrical...

please and thanks !!

well the year and engine plus auto or manual are needed or else this could go anywhere. how can he drive with the brake on....unless you mean it can idle(run while stationary)

Ekay

ooops my bad..

auto and he is barely pressing on it not to hard just enough to were hes able to drive it

B_Swapped93

gonna need new brake pads soon if he's doing that for any length of time. im going to assume it's a stock d16y7 car is prob 96+ is he getting any codes ?

Ekay

its a EG, and yeah stock and no codes

xile6

Z6/b7 manifold? Or the y7 manifold?
And that motor in that car on obd1 needs a tune.
But check for a vacuum leak in the brake booster.
Next check the iacv. It may just need a cleaning.

B_Swapped93

iacv won't do that and no it doesn't need a "'tune'" unless you mean tune up. So it's and obd1 with a what engine the y7 was obd2 only IIRC

hunan beef

Assuming this is really "stock", this would be a d16z6 or d15b7. Not sure where everyone is getting Y7 from....

Does this happen only in Drive? or does it do it in Park and Neutral as well?
Do you hear any hissing coming from the engine?

B_Swapped93

mixed up EK with EG was my bad lol

xile6

saw y7 and eg so thought swap. which a y7 on a p06/p28 will run funny.

but now that I see its a 92-95 b7/z6 I got a better undsr standing.
and iacv can causd it because breaks chabfe the load on the motor.
also had a bad cylinder on a car before and when u came to a stop it would die.

I'd test the brake booster and make sure it's not causing a vacuum leak like xile6 said. You def have a leak. Likely internal to the booster.
