OKay the car run fine. but once i stop at a light really fast or pump the brakes the RPM's go under 500 and jumps and car dies, the car turns back on really fast and runs fine. its just when i stop or play w/the brake. its been going on for a couple of days. but some of the fuel injector cleaner in the gas, doesnt happen as much now, but still happens. Any one has an idea on what it could be??? im broke trying to fix it myself. Also there is this weird whining noise coming from behind the engine. My friend said it might be the diaphram. he fixes american cars and says it should be the same name . its a weird looking part, its on the corner of the engine drivers side, its weird shaped, it has like 2 hoses coming out, some sort of vacuum??
Sorry for the long post. Thanks for any help!!! this board is the best~!!!!!
