Did we ever figure out the "Hot Start Problem"

[waclawb]

Thanks for sorting it out. Finally I got my problem resolved. And got through the emission test last weekend.

This thread is full of win........epic win

Will try this today!

I have been frusterated by my HOT idle ever since I bought it. Thank you so much your my hero too;)

What surprises me is how many people are having this problem. Interesting. Glad the fix is so easy though!

it DID fixed it :cool::cool:

thanks man!

Luckily, this has never been a problem in my "IS." HOWEVER, My 85 318i with the ever solid M10 engine is doing this. I wonder if this same fix will work for that too.....

im trying this nright n ow onmy 318i....i cnt find a black and white striped wire.....found a green one.....tried unplugging....nothing changed. i felt aroundon the main group of cables and it feels like there is a plug in there....

Wow, I don't want to jump the gun and jinx myself, but I think it fixed my baby too! Thank you speed.racer! I too think the idle was becoming rougher with time, which is why I thought I'd check back in with this forum and see if there have been any new leads before I dumped more money on sensors.

I also agree the the throttle response seems much better in low rpms. I'm falling in love with this car all over again!

Makes me wish mine was plugged in, so I could go and unplug it!  Mine is taped safely apart on the outside of the harness.

I get low 20s in the city.  I'm taking it out for a long trip this week, I'll report back on fuel mileage.

I edited my post to include the part number information between the US and Euro DME EPROM.

My car is running like absolute crap, with or without the wire . It's running VERY rich and it stalls very, very frequently. Since I've had the car (approx 40k miles) I've replaced the ICV, the camshaft position sensor, cleaned the throttle body, put fuel injector cleaner in, the works!

I really need your help guys, this is my only means of transportation Thanks!

Can this be done od the E36 M42?

please someone??

I don't know about the e36...but they're practically the same car.  Can you find anything like that plug on the wire harness going across the firewall?  Our e30s have them taped on the outside, just begging to be plugged in.

Here's a few quick tests that won't take much time...do the stomp test...post your findings here.  I'd check the throttle position sensor, the coolant temp sensor, the AFM air temp sensor & flap resistance.  How old is your O2 sensor?  Not to snipe, but if you think cleaning the throttle body is the works...you'll have so much fun learning on this car...:p

I forgot to add my mileage figures from my earlier post...I get low 20s around town and I've hit 35 highway.  That's 42mpg Imperial, 6.7 L/100km (I can brag in metric too).

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?
