Spring is coming. Be aware of Acura's "hotsoak" problem!
For those of you who dont know what "hotsoak" is, have u ever driven your car, then shut it off, then have trouble starting it again? It cranks, but then it shuts off unless u keep your foot on the gas for about a minute or so. I was having this problem with my 99tl last year. The guy at the dealership told me that the problem occurs when the weather is warm, and gasoline company's are still using this additive that they use during winter months. In order to fix this problem, they will need to replace your cars ecu and fuel pressure regulator.
I was going crazy trying to figure out what this problem was, until i finally took it into the dealer. I figure i pass along the info for those who have had it, or have it in the future.

I've never had that problem, but I'd think that you'd just fill up with the summer blend of gas and it would cure that problem.
personally I think that every car would go through this, since Acuras arent the only ones using the blend. thats just my opinion though.

samething happened to me when i first bought the car but after i filled the tank with fresh 92 gas it went fine. dont think i ever heard of changing the ecu or fuel regulator but i can be wrong.
p.s. the car had been on the lot for awhile so it still had winter blend gas in it, i bought it in the summer.

yea this is happening to me and my dad thinks its the sparkplugs. but this happens once in a while and unexpectedly. usually after I wash my car and park it for a while. so did you do what the dealer told you and did it fix the problem? thats seems a little weird to me that you have to change the ecu.

You cant. The gasoline companies switch it during the year. Why would you need 'summer blend' in winter or vice versa?
I believe the additives they use are different depending on the season, hence the summer and winter blends, for whatever reasons. There is no way that you would have to replace your ECU or fuel pressure regulator because of that.
Think about it. If that was the case, EVERYONE would have to replace those parts. Not just us Acura owners.
I think that the dealer got you good, but then again I could be wrong.

well that tells me its a scam right there
All warranty parts must be kept and marked for the acura warranty rep to come approve.
Not trashed before the customers eyes.
What is the cars mileage/kms now?
Anything over 60k miles will benifit from new plugs and a sefoam or other injector type cleaner in the gas tank.
NGK Iridium plugs at 7 bucks each are cheaper than denso and last longer.
Changing the rear plugs is a minor pain something I want to have done only once on the tL

they did not charge him for the repair- thats the important part of the story, and as long as the car is better- who cares

The only time I have seen heat soak as an issue, was on small airplanes- with fuel injected engines and the way the fuel lines run on top, substanial heat rises and can percolate the fuel. After 30 minutes its no longer a prob and starts right up. only first few minutes have potential problem.
We just park nose (engine air inlet holes) into the wind and open the oil cap access cover on top of the cowling (hood), that acts as a chimney and lets the heat escape.
While some of you may fly really low in your ride, its not the same thing
if overly concerned:
On a long scorching summer road trip and you pull into a rest area, pop the hood while you are parked- that will prevent any problems.

Maybe if the OP had seafoamed his TL, it might have saved him the headache of having to actually go and get those parts replaced. But like you said, the car is no longer having that problem.
But seriously, if the additives were to cause this problem, wouldn't ALL vehicles (minus diesel/big commercial vehicles) have this problem and have to get both parts replaced? It just doesn't make sense to me that just Acura vehicles, or more specifically TLs, would encounter this problem.

I appreciate your willingness to "warn" us of this problem, but I think you were fed some kind of mechanic BS they make up when they can't explain something.
So what they are saying is that every year I need to replace my ECU and FPR when it gets warm? There would be a lot of pissed off people driving cars out there.
I wonder what the gas companies do for an indian summer.... or a warm weekend..... or even a cold snap. That could mean half a dozen ECU's in a year. Damn - I'm gonna get a bike with snow studs. I'll be Schwinn'in it to work from now on.

i'm kinda nervous about this now. this is the first winter -> spring that i've had with my TL. but all the years i've lived in minnesota with my mom's old legend, accord and now camry, i have yet to see any of those crap out on her.
"In regions where higher volatility fuels are used during the winter to improve the starting of the engine, the use of "winter" fuels during the summer can cause vapor lock to occur more readily."
the only way i can see this happening as a result of the different gas is if you pumped gas in the winter. sat it around until scorching summer than started her up with the winter blend still in.
which im not gonna. so if this happens to any of us AZiners, be sure to keep the community posted i guess

A friend of mine who had a 2000 TL, had the same problem. The mechanic at Acura told him that it depends on which region of the country u live in. He also performed the same procedure for him for free. Ironically, just like me, my friend never had the problem again.

prob just your Idle control valve. This happened to me like twice a day for like 3 months and i cleaned out the iacv then it stopped. Heatsoaking just sounds like something that the stealership would make up so that they could get rid of an ecu and a fuel pressure regulator that was just gather dust on a shelf and then just cleaned out your intake too. hah
