I use my 7 as a daily driver and I find that after driving it for an hour or 2, it seems to loose most of its torque and basically has no low end power. I am driving in NW heat so its not too warm here. After it cools down for a few hours its back to normal and its very responsive.

Does anyone have this problem or know what its due to? Thanks for any response. -Evan

 

clogged cat?

 

maybe... Didn't know a clogged cat would have that effect.

 

what is your temp... i had that problem, and it turned out to be my radiator had some nasty stuff inthere.... but my heat was slighly above normal... Try flushing your coolent system

 

cool, its about time to do that anyway, my temp gauge sits right below midrange so its staying cool unless the gauge is broken. Any other ideas?

 

hmm I see... well if feels like the car is just tired, after it takes a rest for a while its perky again! Could this be due to a clogged or dirty radiator?

 

Do a coolant flush, oil change, plug/wires (if they are not relatively new). If you got cats try and find out if they are clogged or something, or take them off if you got no emission laws where you are. Not sure what else you could try. Good luck with it.
