Well after replacing my headers a month ago I started having an issue. When I would start coming to a stop the car would drop in rpms. The issue slowly go worse and worse to where now if I have to slam on the brakes the car dies. After pulling codes I replaced my tps and saw a vacuum line on the egr valve came off. With those fixed I still have the stalling problem and actually the car will die if i press the brakes hard when im stopped with the transmission in neutral.
Now I have gone through the surge idle check list and didnt come up with anything. Ive done both KOER and KOEO tests and nothing comes up. I do still need to check the voltage on my alternator but dont feel this is the issue. Also all my vacuum lines and sensors were replaced about 2-3 years ago and honestly Ive probably only put 10k-12k on the car since then. I did recheck all the vacuum lines and replaced the ones going to the charcoal canister but everything else looks fine.
I did notice I was getting a hissing noise inside the car that got louder as the brakes were applied but its seems to have gone away. When the noise was noticable though i never had any braking issues. Now im really thinking its the brake booster causing the issues or maybe the check valve on the booster is clogged. But has anyone heard of the booster causing the car to die? Is simply pulling the vacuum line to the booster and stepping on the brakes to see if it dies a good way to check for a bad booster? Im just pretty frustrated after spending the last few weeks slowly checking everything i could think of.....
