PEPS please HELP....Car Stalling at idle
well for the past few days my car has been stalling at idle. It used to take about 45 minutes of driving before this became a problem but now it seems to happen after about 2 minutes of driving from a cold start. So I called RIPP today and they told me to turn up the idle screw. So when I went to go do that I hear a huge amount of air (like air leaking). Now i have the SDS and i have heard many times what it should sound like and this is not one of them. Under normal driving conditions that car drives fine, but when I stop and come to idle the car starts to putter and if i dont give it gas it then stalls. after having it run for a few minutes at idle, and pushing the TB so it didnt stall, i shut the car off and a SES light came on that was P300, multiple cylinder misfire (this is also new). So i checked all the vacuum lines and from what it seems everything is connected, and I cant isolate where the air sound is coming from. and so everyone knows it is not the sound from the blower. it sounds like a seal or something but i really cant tell where it is coming from.
any info would be helpful. thanks
