Unhappy My baby... dead at 1050 miles.

Hi All,

So I broke in my car as stated in the manual... I was really gentle. At about 800 miles, the car started to sputter a little bit. I pulled over to check if the gas cap was on tight, and it was, so I kept driving. It would sputter every now and then, and all of the sudden the check engine light came on and it was doing really bad. About 15 seconds later, as I was pulling over, the problem went away.

For the next two hundred miles it would sputter and shutter and pretend like it was going to die, but this only happened every once in a while. I took it to the dealer for an oil change at 1020 miles and the tech said it was probably bad gas (even though I filled it with different fuel from a different vendor) or a 'hick-up' in the fuel system. Hmmm... anyway, he said it should be okay and bring it back if anything goes wrong again.

At about 1050 miles, it kicked the proverbial bucket. It was doing fine (the hesitation every now and then)... then as I pulled in to my neightborhood it really started choking. As I slowly pulled in to my garage and put it in neutral it got really rough, I smelled gasoline, and it died.

The tow truck is on its way to my house.

The tow truck just took it away... I'll keep you all posted about what the service dept. says when I talk to them sometime tomorrow.

sounds like a bad coil pack or ignition problem.


to bad it's gone though it would have been super easy to check if all the connectors for the coil packs were on tight. Sound kinda like one was working itself loose after not being installed fully during assy.

O2 sensor maybe? Did it "clean out" at higher rpm? I guess you already have it at the shop so on-line diagnosis won't help much now. Bummer, but at least it's under warranty. Does Subaru provide loaner cars for warranty work?

Not the least bit surprised - being in auto manufacturing, I've seen all too often that $#!^ happens. No big concern for the rest of us at this point, HOPEFULLY it's an isolated failure. My sincere condolences...

Default UPDATE... call from the service dept.

I just got a call from the service department. They said the car was just saturated with fuel.... completely flooded. Doh... and I smelled gasoline before just after it stalled, too.

I *really* hope this didn't royally screw anything up. I'd hate to damage the turbo and have it fail 5000 miles from now, throwing turbine blades in to my exaust system and whatnot.

The ECU saved the error code that came on during the around the 800 mile mark, but they didn't tell me what it was. The dealer will give me a call before the day is up and let me know what else they find.

The flood of gas sounds more like a symptom than a cause.
Why is a fly-by-wire car flooding for hundreds of miles?

I put money on this one that it has to do with a coil pack either working itself loose or failing. I had this EXACT same problem. When the coil pack stops working fuel will continue to be dumped into your cylinder but of course no spark, no ignition. There's nothing really all that harmful that I can think of about this happening.

Depends on if and how much raw fuel is dumped into the cylinders and then attempted to be compressed if there is still momentum and/or the starter is engaged...

Where is the STi's EGT (exhaust gas temperature) probe? On the 02 WRX, when the EGT probe goes out(goes bad) the car floods and sputters and drives like crap (or doesn't drive at all). It happened to me on day on my way home from work. The service department was clueless and didn't know what was wrong with my car. I called Turboxs and they told me it was most likely the EGT probe that went bad. So I up pluged the connection going to the EGT probe and magically, the car ran great again. Before this my WRX would hardly run at all with a flooding problem.

Worth a try if the problem persists

I agree, this doesn't sound like it would have caused serious damage. But, if the cylinders were flooded with fuel, an oil change should be in order as part of the service.

Rings can be easily washed out by the dumping of excess fuel and lack of complete combustion ofr extended periods of time. Just something to consider.

I hope the tow truck that hauled your car had all your cars wheels off the ground and didn't just pick the front up and left the rear wheels drag.

The only bad thing that can happen when a car is flooded and/or running extremely rich is that you can foul up the cats pretty bad. The engine itself is probably fine. Hopefully you'll be OK. Don't lose too much sleep over it!

Given that the STi doesn't have a pre-cat upstream from the turbo, it has no stock EGT sensor (or a need for one).

As long as were laying bets, I choose a bad A/F sensor.

Default Another small update...

I called them right before they closed. They still have no idea what's wrong, but I think they used most of what little time they spent on it today just getting the excess fuel out of the engine.

I've mentioned a couple ideas I read on this and other forums. They are going to follow up on a faulty Fuel/Air mixture sensor idea. I'll mention the exaust gas temperature sensor tomorrow. Keep the ideas coming.

I want my STi back (it's a lot more fun to drive than the full size truck with a 4 speed automatic that I'm borrowing)

Don't ask them about the EGT sensor... you don't have one. As was mentioned above, the WRX used one to help protect the up-pipe cat. No need on the STi.
