Acceleration problem 110km +

[Andrew_Pakula]

I seem to have been having problems accelerating past 110km/h and beyond lately. I have an automatic and my transmission appears to be shifting smooth and is able to accelerate up to 100km/h without any noticable problems however once it gets to 110km it doesn't seem to want to go any higher unless I really push it. Before I could easily get it up to 140-160km/h fairly easily but now it just feels like once it gets to around 110km I doesn't want to accelerate any further.<P>Is it likely a torque converter problem? Could it be anything else?<P>Any suggestions apperciated.

Whats up Andrew, <p>K, i had the same problem, but it MAY NOT be the same thing ...not sure. <p>In the beginning it started out as u said, wouldn;t be that quick on the highway and i also had a tough time getting up hills...(remember i have a 4 banger, so u may not have this problem) anyways, it gradually got worse and after a while couldn;t even get on the highway and had a tough time getting up to 60 KM.<p>Jarid than informed me that it could be ur cat is clogged, which later found out he was right, it was my cat , it was clogged! and after that was cleaned out, my car is back to normal, get to 150 KM easy now! <p>HOpe i could help, like i said this may not be the same thing, but anyways......i try..lol<p>Good luck bro...<p>PS: if it is ur cat, ur exhaust may smell funny..

Well when does your exhaust ever smell really good? lol<p>Exhaust just smells like exhaust I don't know if i would be able to tell the difference.<p>Maybe i'll get Curt to look at it later.<p>I actually posted this thread a long time, the problem still kind of exists.<p>I can still get up to 140-150 or whatever but it takes longer to do, so from 80 to 120 is accelerates slow which is bad for when you getting on the hiway.

Hey Andrew, don't know if you fixed the problem yet, but my 2 cents is maybe the timing and or the fuel injectors getting sloppy.
One of the things I noticed with a clogged cat is that there was a huge delay in acceleration when I punched it, even at lower kms/hr.

Yea I will definately have to check out soon to see if I have a clogged cat.
