Stalling after full track session
 

I'm at the auto club speedway with speed ventures and on my way in after the session my frs seems to have stalled itself. I didn't get to do a full cool down since someone had their car catch fire but when i slowed down and put it in neutral, it died. It died again when i put it in neutral while parking. I had the the cel idle problem when i first got the car but the dealership fixed it and i haven't had a cel since. Wondering what might be the cause.

Probably detected overheating and shut itself off

and outcome?

also interested

Does it have a CEL and SL now? Did it start idling correctly after awhile?

VAPOUR LOCK.... nah probably not, I just like saying that phrase

The more you track cars and the more cars you track you'll experience this. It's usually just heat soak. During the track session everything is very hot under the hood and afterwards, during idle the air moving into the engine is moving slow enough that it picks up enough heat and the sensor/computer doesn't compensate fast enough to bring up the revs and it stalls.

My S2000 did this on the first hot day of the summer, and occasionally after a track session. My CRX that I race does this often and most folks that have tracked enough cars have developed a habit of keeping the revs up a bit (800-1k) after coming off track because of this.

I wouldn't lose any sleep over it.

Thanks for the info guys. After the next session I had some idle fluctuation but did not stall itself. I think it would be alright with a full cool down lap or drive around the staging area for a bit.

Got the same issue !

I would always advise a cool down lap just as much as a warm up lap. Drive it in a higher gear at a normal pace slow enough that you don't even have to use the brakes.

Good rule to start with - if you are still picking up rocks with your tires as you come in the pit area, keep driving, its still too hot.

and remember, no parking brake!! :burnrubber:

Had something similar happen during the middle of my 3rd session today. I was WOT down a straight in 4th when the red flag came out so I slowed and pulled over. We started moving again after 2 min. and I noticed the TRAC OFF light was on. No CEL that I saw. After pitting and restarting the car, it was fine.

I'm hoping this was just a random heat-soak/idle issue. Temps were about 85 degrees and I was running 100 octane to guard against possible DI seal issues. Other than that, the car ran like a champ. Planning to run 100 octane again tomorrow.

IMO an oil cooler is almost a requirement if you track your car.

Check your vacuum line near the top of the block
Mine blew off
You just need to put a hose clamp on it and your good to go
Ill post a pick when I get home

Probably heat soak, your car had a lot of excessive heat and since you came to a stop or much slower speeds, your cooling capability plummeted and your car stopped itself to prevent more heat building.

Word of advice - after running laps BEFORE you lose a lot of speed (eg: rolling into the pits or safety areas) put your HVAC on HIGH HEAT and put the fans on FULL.

The car draws air across the hot engine to heat it up going into the cabin and it will help cool off your car faster. It will make you uncomfortable but you can sweat it out with the car.

Also, an oil cooler is definitely needed if heavy track use is a possibility.
