i drive an 05 tl 6mt and recently i had the knocking noise in my engine but i think that was due to me not putting in the correct gas......but now my acceleration lags a little what may be the problem or is it that i just have to let my car work in the new grade of gasoline???

 

Could be several things. Your ECU may need to readjust to the higher grade of fuel, you may be using less-than-quality fuel (never do this), or you may be in need of a good fuel system cleaner application.

Drive the car for several days and see how it does. If you have never used a quality fuel system cleaner, pick up some SeaFoam Motor Treatment fuel system cleaner and follow the directions. And never use "cheap" fuel - stick with the name brand products.

BTW, I am the original owner of an '04 manual TL and I can assure you it has absolutely zero throttle lag at tip or under full application.

 

I agree with this. The TL has the best throttle response of any DBW car I've ever driven. Every Ford and Toyota is evident you're driving a DBW car. I wouldn't be able to tell if I didn't already know in the TL.

 

ok im going to drive it a couple more days before i start to have a heart attack. Also one of my b uddies mentioned it could be my clutch? any one have any answers for me on that one. Another thing is that it does that funny thing with the acceleration even in gear and everything but like you said im going to let it run and try seafoam btw idk were to get that at if anyone can help. thanx bros

 

You can obtain Sea Foam from many auto parts stores: http://www.seafoamsales.com/where-ca...-products.html

 

walk in to any parts store in your town
ask for a can of seafoam liquid- about 8-10 dollars,,low as $6 at walmart!
add that 16 ounces to just under a half tank of gas, for `cleaning strength` dose

use name brand stations for `Tier 1` quality gas- which has more cleaners than the govt minimums--up to twice as much by some rumors
Works better- keeps the TL happy

 

if its your clutch there will be rpm increase quickly with little forward motion of the car

The TL clutch feels good right up till the day it dies,,has special system to make it do that

Need to clean the TB air plate too- remove tube from air filter box to TB
spray plate inside TB with carb cleaner or TB cleaner
Have helper turn key to ON- not start- that opens and closes the plate in a self test so you can get the back sprayed
do it a few times till its shiny clean on edges and both sides
wipe up any runoff- car will run funny at start as the cleaner moves thru but its ok

 

so your sayin i wont have to buy a new clutch if that is my problem. And there is rpm increase quickly with little forward motion.

 

Now that's a different situation entirely. We need a good description to help out. RPMs rising without the corresponding increase in speed is the clutch (or wheelspin lol). The problem should get worse under heavy throttle in the higher gears assuming it's in the powerband.

 

Are you the original owner (I doubt this because of your age), or did you buy it from an individual or a dealer? How many miles does it show on the odometer? If you bought it in a private sale, did you observe how the owner drove the car - operated the transmission/clutch?

 

I am not the original owner I'm the second owner and it has about 58k. My car feels like it has no power when I put it in gear my rpms will go up sometimes even shoot up without any increase in speed. And if it is my clutch should I just go aftermaket? Also if it's my clutch how long boil I expect before it's completely finished

 

Can you be more specific about rpms shooting up without increased speed. A few hundred, a thousand? What happens to eventually increase your speed? Do you have a sense that something catches, is there a clunking? Not to be pessimistic, but it sounds like it could already be toast.

 

The time is now. The more you drive it with it slipping the greater the chance of hurting the flywheel.It will probably go out any day.

 

another small input that you may consider, although unlikely.
acceleration lag is sometimes caused my motor mount failures. the side goes out, then the rear, and then eventually the front.

 

I'd stay with the factory unit myself. As for how long you have left?? If your description is relatively accurate and it is slipping as much as you have indicated, get it fixed as soon as possible. It's already gone.

 

yup she's hurting.I didnt even consider driving her today that clutch is gunna have to be replaced sometime this week. Any certain types of clutch kits i should look at for a reasonable price

 

Gasoline is a very important, I am using mobile1 5W, once you use this gasoline then you have to keep using this because this gasoline will protect your engine, it makes the engine more smooth......Thats what I heard from dealer

 

Or maybe you can try the +/- gear to check it out, try the first gear and accelerate with first gear....hope you will see the different

 

^^^ You really should read a little more before posting anything ^^^

 

^^^^^^I did only read offsettl2005's question and good gasoline can reduce noise from engine, thats what dealer told me ..

 

A higher octane can reduce pinging if it pings. Most dealers are surprisingly uneducated on a lot of car stuff.

 

????

 

Boy, if that isn't the truth.

 

figured it all out it was my clutch and flywheel and i just got them replaced thanx for the help though bro's

 

i gt a 05 6mt tl with 89k mi on it. my problemis that when i first got the car which is about 3weeks ago the car was really responsive.it would just fly on the first. but now i am noticing some lag. it responds to the clutch but it moves much more slowly. is it clutch or the ecu? and how is ecu adjusted to the grade of the fuel.i am using 91.not sure what the previous owner used.

 

It could be the APP Sensor.

but i havent noticed the error code or the vsa light (!) coming up.

 

another thing i noticed is that the acceleration lag is mainly on the first and the second gear. when i throttle hard in the first two gears, the rpms shoot up(around 5000 rpm) but the car doesn't respond to that.

 

okay, with the clutch fully "engaged" (clutch pedal out, not pushed in) in first gear or 2nd, if you floor the throttle you experience a rapid increase in RPMs and the car barely moves if at all?

I believe your clutch is now slipping. You will probably need to have the clutch replaced.

You should get it to a shop ASAP before you ruin your flywheel.

Look up SouthernBoy's posts on how to drive a manual transmission as well. Judging from the fact that you did not know that the symptoms you were experiencing was a slipping clutch, it's a good start.

Good luck.

 

thanks for the reply ez12a. yea i havent driven manual transmission for couple of years now so maybe i am not driving it correctly.

 

ok so i took the car to B-Line mechanics( read a lot about hem on the forum). they took the car for a spin and checked the air filters etc. accorrding to them the clutch is fine and the car drives great. bu since they dont drive it everyday they cannot tell the difference.

they did tell me about trying out a different brand of gas. gonna go with shell.
any input from you guys?

 

from the description above, it sounds like your clutch is slipping

 

what i meann by car not responding to the rpms is that the car is slower than the corresponding rpms. it doesnt slip because in 4th and 5 th gear the car is fine , even at the third. its just first and second, when i floor the throttle the car doesn't shoot forward like it used to.

 

i think it would be best to record a video if possible of what you're describing.


given a low gear ratio the tachometer will rise a lot faster than the speedo. They're not 1:1.
