Not sure, what is the 3GS limited to? I went max high 140's but nothing pass it yet. It's just weird that the amber engine light came on but not the red one.

henry, keep in mind hes in canada so hes really only taking about 110kmh (70mph) to 140kmh (90mph).

ive never had a problem driving my GS on the highway, ive had it up to 100 before with no problems.

If I drive normally around 140 it doesnt show up but if I slam the gas it does, thats the weird part I dont get.

140km or 140mph? good point IXI187IXI

if at 140km, you floor it and it comes up, something is wrong with the car

Hmm, guess I'll get that checked out. I go to 150 no problem if steady climb but if flooring, light will come up flashing. Sorry meant to say km/h.

I'm at a loss here. Why did you buy the car if you didn't like the way it handled?

The answer is it shouldn't do that... it's especially odd that it comes on and then goes off immediately. Where in Ontario are you? I'm in downtown Toronto, if it's convenient for you you can bring your car by here and I can use my code scanner on it to see if there is anything stored.

Hazard a guess at a vacuum leak.... when you floor it, it creates a lot more vacuum and you might have a hose or gasket loose that the car temporarily detects. After enough cycles of it happening, it might turn from a pending code into a MIL.
