Brake booster
Hello I have a 1988 corvette that’s been giving me a lot of issues like slow starting, misfiring, shaking and a bunch of other issues I’ve changed and replaced a lot including a new distributor and timed it and it’s finally sounding good, the egr code is on but I haven’t gotten around to change that but I went to start it and take it for a drive and when I pressed the brake at idle the engine sounded like it was going to stall. The brake has had trouble stopping the car and the pedal isn’t stiff I assumed it just needed pads but now idk when I disconnect the vacuum line to the booster the rpm’s jump up then calm down when press the brake then the rpm’s don’t change so would this be the booster going bad and could that be why the car takes forever to start?

You'll probably have better luck if you post this in the correct Forum for your year car - not many people over here in the "antique car" sections know anything about '88 Vettes, nor know that they exist...You have a C4. Not a C3.
