Help! Weird engine dying problem! Any Ideas?
Ok, so I picked up a 90 legacy AWD wagon for $300. Had new TOYO touring tires all around. Put new front rotors on, new radiator and fixed the speedo cable. Spent about $350 for that. Not bad. Oh yeah, the finger sized hole in an exhaust valve might have had something to do with the good price.
So I pulled the heads off, had them done and fixed, put a new water pump in while I was at it (About $191 for the head job, $55 water pump and $105 for gasket set), and presto, a great running car. This took about 7 hours total (1/2 and 1/2 two separate days)
OK, so at this point I think, hey, only $1000 total spent. Runs great, handles ok, breaks ok, and even the radio works. What more do I want?
Well, what I want is a car that doesnt have the rev limiter (or so I suspect) kick in when cornering hard WOT (ususally in 2nd) in the right hand direction. The engine just quits pumping fuel (or so I think) because the engine doesnt officially die, it just backs down to idle. You wait a second and bang, off you can go again WOT, unless you are still swinging around the corner, then it gags again and you have to wait for a few seconds before you can stomp the throttle again.
So basically, a -either the rev limiter is getting turned on, b - something is moving from the force of turning and turning off the injectors, c- something I am not thinking off. Remember the car does not die, just stops getting fuel.
Could it be something in the throttle body? just thinking out loud. BTW, nothing obviously loose in the engine bay.
Thanks

$191 for a head job !!! Nevermind....
How much gas do you have in the tank? Long sweeping corners are notorious for starving the fuel pump in some gas tanks (like most Subarus) with a quarter tank or less. If it does this with a full fuel tank... we'll i'd still check the sending unit and all that jazz. It's unlikely to be something wrong in the engine bay or you'd have problems all the time since the fuel is all pressurized and such by then.

Do you have an auto or manual.
To my knowledge, manuals don't have a rev-limiter....or so I haven't heard of one.
The auto's do, and you'll know if you hit rev limiter. Power goes away very dramatically, but it will not go down to idle.
It sounds like you have a fuel delivery issue.
Check the sendors, etc as mentioned, and keep gas above 1/4 tank when driving hard.

I've revved my auto past 6500 in neutral before.
However I have hit the rev limiter while driving......it sorta freaked me out, cause it had never happened before. Basically the engine revved faster then the electronics in the tranny could shift.

Well I am hoping, even though this is problematic, that it is fuel starvation when I have less than a full tank. I will find this weekend at PIR (Portland International Raceway) when I do an autocross.
However, I bet that just for kicks, God wont be smilling and it will still be there every time I take a hard right hand corner.
Blach!!!

99.5% sure it is the fuel pick up. Hard driving with full tank ,not a problem in sight. Get below half tank and hard curves starve and die.

I'm sorry to resurrect this ancient thread, but I was wondering if you ever fixed this problem? My car has the exact same issue.
Anything under a half tank, and the fuel supply will cut out under a hard right corner. Freeway cloverleafs and such are a pain in the ass!
I figured it was a fuel supply issue, but have no idea what to do about it. What did you do?
