Thanks for all of the suggestions. I left out a few details because I was in a bit of a hurry trying to get my car back together!
-Stomp test gave me the incredibly helpful lambda code (1222)
-Throttle position sensor was replaced in January, 2k miles ago.
-Where is the coolant temp sensor and the AFM temp sensor?
-o2 sensor is a year old.
-I know, I have no problem pulling things apart on my car, but there's only so much I can do down at school, away from my garage! :p I threw in new plugs, threw in some Techron in the gas tank and used a zip tie on the throttle cable to raise the idle by 300 rpm and the car drove well enough to make it home! Now I've got the intakes off and I'm replacing all of the vacuum lines.

Hopefully this will sort out my idle issue, but I'm not sure about my A/F ratio. Whenever it comes back together I'm going to test my fuel pressure, and while I'm waiting for gaskets to arrive I'm going to check the coil resistance. Any other suggestions?

I would bet that it's either your coolant temp sensor or your fuel pressure regulator (FPR). When either of these items fails, usually your car will run very rich. Sometimes you can smell gasoline in the vacuum hose of a bad FPR.

Why are you cutting this wire?

Intake temp sensor is mounted inside the AFM. You'll have to pull the connector and do a voltage test I think. It's in the Bentley.

I think the blue 2-prong connector is the right one...the DME coolant temp sensor. I'd test it anyway.

Testing the O2 sensor is easy...disconnect it and see if the hot start problem gets worse/stays the same. If not, suspect it as bad...even if it's been replaced recently.

I have no idea what the wire cutting is about either...please clarify...

That makes at least three of us that don't know. :confused:

I was looking for black and white wire and that is the only one I could find

Ok, put a splice in that wire you cut.

The wire we're talking about is in circled in this drawing.

No cutting required, the wire has simple push connectors.

In your case, I'm guessing you don't have a catalytic converter and the wire should be connected.

If you do have a catalytic converter, then disconnect the wire.

i didn't find that connetor

I drive e36
may not be the same as at e30

Yeah, they tidied up the wiring in the e36, so no plug for you!

To the OP, if you arent drunk enough already, consider me owing you a beer or 2 myself. Been dealing with this for as long as ive had the car and assumed it was a vacuum leak. And add a beer to desktopdave as well for pointing me to this thread.
