You guys are really helpful with a legitimate concern.

I would take it to the dealership but without a CEL I don't know how much they are going to be able to pull from the ECU. I honestly would try not to worry about too much unless it happens again.

thanks lstepnio, i wasnt really too concerned about it...there was no power loss, no cel's nothing changed about the car...it was just weird....i am not worried about it but just wanted to know if its happened to anyone else...thanks..

could it be something with a G-sensor?...actually now that i think abnout it before when i e-braked around a 180 turn, it shut off...hmm....i am hesitant to take it in because as you said...i doubt they would be able to find anything out with no trouble codes...

I had a problem with an eagle talon that was simular. The car would just die without warning or CEL. The car was in for service 27 times the first year.

The replaced the computer, most of the wire harness.

They beleived the problem had to do with a short.

It even died as I was driving it out of the shop.

Go and explain what happened to your dealer. It may be a short or a bad fuel system electronics. Check the Subaru.CA site for information about the STI fuel system. The U.S. site does not have the nifty diagram of how the STi fuel system works.

Can you what would happen if you were making an emergency left turn and you STi died! Oh the humanity.

Good Luck

If the fuel is low you will get fuel surge on left hard corners. It happened in the WRX and it happens in the STI. If on the track due to the higher G force in corners it can happen in left or right hand corners even with a few gallons of fuel left in the tank.

If the tank warning light was not on and there is plenty of fuel I would be worried and get it checked out by the dealer or at least get it logged for future reference.

As it might be caused by a Gsensor I don't think there is any any connection between the 2.

my 2.5 cents worth.

The G sensor? Is that the same as the rollover sensor i read about? I beleive the STi has a sensor that kills the motor if the car flips. I do not know the name ot location of the part but maybe someone else here can fill us in?

The car definitely does not like to be pushed with less then 1/4 of a tank of gas. I was at the track today and anytime I would get close to 1/4 it would hesitate coming out of a long banked left hander. At one point the car died and I ended up coasting for bit until I could pull off in a safe area. Check engine light came on and the cruise light kept flashing.

I unplugged the battery for a few minutes to reset the ECU and all was back to normal. I added gas and did not have anymore problems. Now I Know I will never let it get down near or under 1/4 of a tank.

How much fuel was in yours??

Later,

Enrique

Just because there is no CEL does not mean the dealer won't find a problem... It could be something as stupid as a bad ign switch that would not trip a code.

There are far more systems that do not trip MIL codes than there are ones that do.

To my first point take it in for repair if they can't find the problem then try to find the answer

TR11,

My guess is that you are experiencing gas pickup problems on those hard lefts. An e-brake left is a high-g load which will slosh the fuel away to one side.

I also found the fuel system a little flakey in my STi per my earlier 'ran out of gas' thread. First time warning light came on I went right to the pumps and put in 45 litres meaning it had a 15 litre reserve when the light came on. On the second tank after the light came on I drove less than 75 km and then my car just sputtered and died. There couldn't have been more than 6 or 7 litres in the tank when the light came on that time. As it was sputtering, weaving back and forth gently caused the engine too pickup more gas and drive fine for a little bit. I imagine there would be alot of fuel movement during higher g turns which is what you experienced.

Now that I have the rear seats & interior out to install a rear strut bar I can hear the gas in the tank sloshing around all the time -- it doesn't seem to be well baffled in there. I NEVER hear that in my 323GTX race car unles it is very, very low on gas- and it has the same style of axle stradling tank in it.

My car buddy & his wife just last week experienced _exactly_ what you describe to a tee, including the gauges going dead and the car going completely 'cold' at a momeonts notice. Further this happened several times during normal driving (i.e. straight line on a highway, turn in to their parking pad, parking at the mall).
The only difference from you is that thier car is a '01 VW GTI with 1.8T.

The dealer diagnosis was a bad connector for the MAS at the harness. They replaced the sub-harness and cleaned his MAS then put him back on the road. He hasn't had a problem since.

I don't know if the same thign applies to us/STi but your reports are uncannily the same to what they experienced with a previously reliable car/engine.

I can definitely confirm that.
I've not pulled any interior compents but when the tank in my car is at 1/2 or less I hear lots of fuel slosh. I'd figured though that it was due to our cars not having any sound deadening material.

And what is not needed in my statement?If you like your powertrain warranty I would not use the Handbrake to execute turns,Doing so WILL shorten the life of your differentials.

Ben,
Ben,

The e-brake has an e-sensor in the housing that detects actuation and tells the DCCD to go into open mode allowing jutst such a maneuver. Its even documented in the owners manual.

Click here for more specific info on this unique STi feature.

No harm will come to ones diff's as the STi is built for it.
