60 degrees and full power is finally back.
I forgot how terrible this car runs during the summer months. Now that it's about 60 degrees, the power is back, the surging is gone, and lots more torque. I'm using nearly 50% less throttle to get moving. I almost want to sell the car before next summer.

It almost has to be a sensor because it will improve slightly as the temps drop from 105 to something like 90. But from the low 60s and down it's like someone flipped a switch.
I'm sure it's totally unrelated but my outside temp display is erratic, sometimes 20 degrees off. I almost wonder if the coolant or IAT sensor is doing something similar. Only thing is they are compared to one another at startup to make sure both read the same. Still, most failures happen at higher temps.

agreed! although mind still does heat up a tad...
i lose all my torque within 20 minutes as apposed to the previous 15...
there's something disastrously wrong with my car. i even had the plugs changed, with all the belts and water pump

are all you whoo r experiencing these problems. Do you run a CAI. In the summer months the ground is searing hot roughly 140-150 degrees on a hot summer day the CAI sits right near the wheel well were it would be most hot. I never felt this when i had my stock intake on this was my first summer with my intake on so this was new to me.
Car is running MUCH better now tht the temps r lowering

what about installing the thermoblock /outlaw spacer for the intake and TB?
winter performance all summer long
The rest sounds like an IAT sensor problem

I wish it was, it would make troubleshooting much easier.

I've noticed the exact same thing as you. I'm not joking when i say, i was about to sell my car and buy a 4banger or something it was pissing me off so much. The car literally chugged and went as slow as my 140hp integra at times during the summer.
Im def. going to look into some sensor changes or w/e for next summer. Planning on keeping this car for at least another 2 summers so it will be well worth it....

i wanna trade it so bad but the fact that the car is paid off i dont like making payments again.

as a strange thought-
have you removed the intake manifold and cleaned the EGR ports?
gen2 has a prob with that getting very clogged and requires cleaning every 75k miles or so
That will make the car run funny

I felt like I should update, the car is so much fun to drive now. I hated that surging before, made the car feel so cheap. Now I can keep up with traffic with less than 25% throttle where before it took 50% or more. It's only been a short time so I don't have a large average but so far gas mileage has gone up by 5mpg. We'll see over the course of a few more tanks of gas if it's a fluke or real.
As soon as I get paid I may go ahead and buy the IAT sensor but wait until summer to replace it.

It was 51 degrees last night and when I went WOT in 4th gear at about 75MPH, the car just fricken hauled ass to 120MPH! The cold air is awesome! Imagine how 3rd would have been....cold air FTW

I removed the valve and started the engine. Just like it should, sounded like it had a huge exhaust leak and intake leak. RPMs shot up to 4K before I shut it off. I also manually commanded lots of EGR with a scantool while at idle and nearly killed the engine. However, when I do the timing belt and valve adjustment I'm going to take a good look.

That sucks that you are having that much of an issue during the summer. Even here in the south, I have not had any issues during the summer. I have the IAT moved to the Injen CAI like the AEM setup. I do notice the boost in power during the cool mornings, but my summer performance doesn't take the hit yours takes.
I run 93 octane Shell year round. GL with trying to figure out what is going on.

IAT didn't fix mine. It was slightly better, but today, it got back into the upper 80's and the car acted like a raging POS. Sat in 20mph traffic for a while and I thought it would never get back up to speed. I bought a Knock Sensor at the same time as the IAT, but haven't gotten around to tearing into the upper engine again. I tried all of the EGR cleaning and such. Didn't help ANYTHING. Even replaced the EGR valve trying to fix another issue. I finally changed the APP sensor to fix the surgung at cruise. NOT the same issue as this one.
stupid florida, its 85 degrees RIGHT NOW! its gonna be in the 90's for the next couple days with ridiculous humidity

Are these surges intermittent throughout a lower to mid RPM range? I get this about 75% of the time. I'll be accelerating and I feel the car surging like there's a sudden loss of power then it comes back a second later (happens 3-4 times). If I'm in the upper RPM range (4000+), it never seems to happen. Some days it won't happen and the car accelerates much more smooth/quicker.
I'm going to try that TBA Throttle body adaptation or whatever where you put the key in the on position, press the gas pedal down for >5 sec. and put the key back to the off position (wait 2 minutes).

I know what you mean about colder weather. Lat night was -3 celsius outside and the car has never performed better. No surges at all compared to when its really hot I can feel them sometimes. Power is so linear and so smooth. Wish the car would perform like this all the time.

I guess its no wonder why the car runs good when its cold only.... its made in canada !!
im always hoping someone will eventually come up with a solution for this problem. I love this car when the weather gets colder but as soon as it warms up when you actually wanna enjoy it the most it sucks ass.
I would love to trade it in but it would be a big loss and then again i think i would miss too.
the only good thing out of it... it always kept me away from modding this car much. But now the way she is running i would even consider putting in a supercharger but i dont trust her....

would you say that some of us are isolated cases or is every TL out there exposed to that same problem ? and many just dont seem to recognize it much...

Man i thought my TL was the only one that did that this summer. I spent the summer in Vegas and I remember complaining to all my friends and my dad that theres something really wrong with my car. I almost took it in to Acura to get it checked.
Now it's running perfect

I plan to take the scanner home for a weekend and drive the car non stop with it data logging until I find a glitch. If nothing is found, it's time to start looking at mechanical issues.
