So, my car idles extremely low, shut off at times and also has a hard start... I have to blip the throttle to start it and keep rpm up or to keep it from not shutting off. It idles around 250-500rpm. Vacuum pressure is at -10psi, if I pump brakes the vacuum goes around -7psi may even shut of at times.. Sounds like a vacuum problem but I can't seem to find any leaks.. I've search the threads but not seeing any low idle issues... Does anyone have an idea as to what my problem might be? Or has anyone had this problem before??
