When i accelerate above 85 mph racing someone , my car starts engaging traction control.. is this normal. Im not drifting just accelerating in a straight line. no spinning tires. when i turn off esp its fine... so in order to race i need esp off?

that shouldnt be happening at all

how are your tires? is it flashing or is it constantly on

What tyre sizes are you running front & rear?

i had same problem, but mine would kick in after 2-3min driving at 80-85 mph or higher... and i had three different tire set ups including stock, did it in all three though the speeds at which it did it were fluctuating according to circumference.

did u ever get it fixed?


the stock size ill take a look today when i go drive. it just flashes and when i slow down and return to a normal speed 70 -75 it stops... it just sorta flashes feels like brakes are being engaged for safety

Onstar? .

Its a 2001 so i dont think it would have onstar besides that isnt onstar for gm vehicles

imo you shouldnt be racing anyone illegally anyways... leave that stuff on the track. I use to do that foolish stuff back in the day, but as I've gotten older and seen people wrap lambos and other cars around trees in person I tell people to do it the legal way where theres safety workers around just in case something happens. You may never know when someone could cut in front of you in the highway since they dont expect someone to becoming by at 85-100mph or even pull out of the street not noticing you coming on.

lets solve my problem first... its deff not normal for the car to randomly engage traction control. i hear ya on the racing thing, personally ive never taken the car above 90 and after 95 im done accelerating. Just would like to make sure the car is running with all things fixed. thanks phister

Ivan ~ didn't you have a wheel sensor problem recently? All wheel sensors need to be OK.

If you are running standard tyres all round you will be OK. If rolling circumference difference between back & front exceeds about 4% it will trigger the ESP.

And you are stock? no camber kit, spacers, etc?

Yeah i guess thats it . I found the sensors for 37$ each
Im completly stock the car did have an accident a few years ago ill take a look to see if the sensors are damaged . Any other ideas ?
Also how do i get ahold of a star tuner

glynn where are the abs sensors located
