Okay so I'm away at school right now and don't have my Bentley handy. doh! So I need some help with what is what.
Anyways my car has had this persistent surging idle problem:twisted: now for like a year. I have been slowly replacing the parts that contribute to this symptom in order of cost. So far it's been check for vacuum leaks, clean the ICV, replace the ICM, and replace the TPS. Next on the list is the o2 sensor.
So what I did today was unplug the o2 sensor before I started it and let it idle for a bit to see if by doing so it changed anything.
So it's idling (ever higher as it warms, because that's what it does, until about ~1500 RPM at which it starts surging up and down) and I'm cleaning off the snow, and I'm smelling gas. Bad. I shut it off and pop the hood. And this is what I see:
So at the yellow T-fitting in the picture there is dripping gas. The hoses running into the fitting are soaked in gas. And beneath the fitting on a hot intake manifold is a puddle of gas. Yikes.
I want to make it clear that I understand that when I unplugged the o2 sensor I made the ECU switch to a rich fuel map. But I don't think it's supposed to make fuel leak like this. The fuel stench on my coat makes it smell like someone fired up a weedwhacker in my room lol.
my best guess with out a Bentley:
Bad FPR, which is also causing my surging idle.
