i have a 2006 Acura TL, and lately when i drive, i feel the car has gotten extremely sluggish and the acceleration is just horrid. Currently i am at 64k miles, and have been keeping up with all oil changes / air filter changes. Any suggestions to why it could feel so sluggish?

 

Have you reset your ECU lately? The car can become a dog if it has not been reset in a long time. Assuming you have an automatic.

 

High ambient temperature... Air filter...

 

How do you reset the ECU? Could it also be worn spark plugs?

 

Either disconnect the car battery for 20 minutes (make sure you have your radio codes beforehand) or read this thread.

your car is heatsoaked !!!

the TL looses humungous amount of low end in the horrible summer....once the temperatures come back down, you will be good....

 

Do the Ultimate Cooling Mod and you will never have a problem.

 

done that and never been cooler

OP might wanna look into TB coolant bypass as well...

 

I did the TB coolant bypass and I noticed a little difference.. nothing crazy, though. I'd say with everything else you can get some significant drops in temp!

 

I did every cooling mode possible and it helped about 5% percent. Its unbeliveable what the heat does to this car. Everything goes to shit, i dont even wanna drive it how bad it is. And on top of that the gas milage cuts in half if not worse....

 

Heat index has been as high as 110 around here in Chicago and I have noticed no sluggishness on my 07 Type S 6mt. Atleast nothing abnormal that every car experiences during such high temps. Im still convinced if guys on this forum are reporting that it is horrible and sometimes needs to be floored then there is clearly a problem and it is for sure more than just "heat soak" issue.

 

try accelerating up from 43 mph on 5th and let me know...

 

yes there is a problem, there are that many people that pay attention to it that much. Once you catch onto it you can always feel the power vanishing....

The funny thing is that many and many more are starting to complain about the same symptoms. Ive never seen any car loose that much power from heatsoak. Its amazing. My car feels like i starts off in 2nd gear. and thats how my powerband continues...

 

My 07' TLS has the same exact problem. When I floor the pedal from a dead stop there is NOTHING, The car has no power & is a slug, until Rpm's hit about 3,200 then a surge. I've reset the ECU endless times, gone to the dealer only to be told: "It's fine" I change my air filter every 15,000 miles, only use premium gas, add sea foam to the gas tank every 10,000 miles & still a slug. It never ran like this ever before. No fault codes in the computer. Last week the dealer offered me $14,000 for it & I'm still thinking about it, get rid of it & buy a 09' G8 GT with 360hp. I've NEVER owned any car in my life like the TLS with such a pathetic loss of power. MY 98' accord V6 with 255,000 miles runs better than this POS.

 

Trade it off ..

 

same problem here buddy.... this is worse then an unreliable car. Here either there is no fix for this issue or we are chasing ghosts cause there was never a check engine light or any code for that matter. Im never gonna buy an acura again. Im waiting for the Golf R to be released. As i said in previous threads, when i was shopping for cars with my dad for him, anything we drove and everything was much havier and less powerfull, yet all of them felt so light on there feet. Smooth acceleration, torque and no lag whatsoever. That experince dissapointed me even more...

 

@TVL, what your experiencing from flooring it at a dead stop is probably the VSA kicking in to stop the wheel spin. If you turn VSA off it should spin/roast tires and haul ass....Its been pretty damn hot around here too and I'm not getting what you have and my car has 108,000 miles on it.

 

I understand the rant....anyway how many miles do you have on ur car ? 15K sounds a little tooo less....

There are couple mods you can do to avoid the heatsoak and I think you should look into it....most of them are free:

1> Ultimate Cooling Mod
2> Throttle body spacer/Thermal Gaskets
3> Intake manifold thermal gaskets
4> Throttle body coolant bypass
5> I am working on something and will let you know once I see the results are worthwhile...they look promising so far

I would try these....1/4/5 are free and 2/3 are $60-70 each....

I think this car has the best of both worlds....it has the luxury to offer and the styling to stun and the power to impress (kinda)....I would pick the TL-S anyday....earlier i used to this this is a chic car but then i realized this is more of a chic magnet coz the way the chics used to digggg my car

I would suggest doing some of the mods i listed about....this will cool down your engine bay a lot....

I hardly doubt it was the VSA....i think what he means is he has to floor it to have the car to go anywhere....

 

I have all the cooling modes, when it goes into that sluggish mode there is almost no help at all. I have UCM, all plastic removed, all the p2r spacers... evem redline watter wetter . Throttlebody coolant bypass... and so on.. High flow cats, which should help with heat aswell.

 

Ok I just changed my spark plugs. its an 2005 with 38000 miles on it but i still gave it a shot, not thinking it would do anything but it seems as if it helped. The car has much smoother powerband then before, didnt notice the sluggishness as of yet.... further testing will tell

 

i heard somewhere that you should not use water wetter....I think i spoke to IHC and he was saying something about it....lemme try to locate his email....

spark plugs shouldnt change much....but if you have been putting seafoam in your engine oil case couple times, the spark plugs might have been begging for a change....but still the plugs shouldnt affect much....

and WOW 38K on an 05....i got 152K LOL

 

well i work in the New york city but live in Jersey... its not worth to drive the car to the city, first the traffic second the tolls and the worst there is no parking, but if you want parking you gotta pay big time . I mostly drive it after work localy or on the weekends. But lots of times i do work on it, one of them is to try locate the problem here and washing waxing and so on .... I dont have the ability to rack up miles

im sure i would drive it more if i didnt have to deal with this problem..

 

i did my masters from NYIT....59th and columbus circle....and lived in jersey as well....and while i was there for 2 years i learned a very important lesson.....

"dont take your car to NYC"....use public transport....better/faster/cheaper/safer LOL....parking is like $24/hr....i was like u shitting me

 

another thing i forgot... potholes in NYC will destroy your car

 

Ok today, hot weather and very humid as well, with the new spark plugs the car felt the heatsoak a little but not even close as it used to do so. I guess i had a problem with the spark plugs in general. So far so good. If it stays this way i wouldnt complain much.

 

^^^ sounds great....

today i did my coolant bypass and removed my MDX spacer so I could send it off for being ported and polished....damn the coolant bypass kicked the sluggishness out the door
