ok so im totally stumped ive got this annoying problem whenever my car warms up and i drive around it starts wanting to die when i hold down on my brakes, it keeps getting worse and some times it dies, so i thought oh its gotta be the booster so i replaced it still does it, all the vacum lines to the booster seem good no leeks and i replaced the one way valve also if anyone can help id appricate any info thanks .....

 

anyone any help would be great thanks..

 

wtf no one

 

You say when your at an idle WHILE braking, it wants to die. What about if your just idling with your foot off the brake?

 

check your alternator and battery

 

your RPMs should drop slightly while applying the brakes at idle. if your car is idling low, this could stall it. if your idling btw 800 and 1000 and still stalling it has to be electrical. have your bat and alt tested. most automotive stores can do that for free.

 

so thanks for the replys so battery is good alt is good it does it at an idle or while ive been driving but it only does this when its warm, it seems like the idle might be low but at an idle with no foot on the brake it idles between 8 and 1,000 so it seems fine im lost on this

 

check ur idle control valve

 

are u talking about the iacv and if so wouldent this make the car run funny or check engine light
