it recently snowed where i lived and i had got a flat tire a couple days before..i got a new one a little after it snowed and when i started to drive on clear roads with snow on the side my car has been good in 1 and second gears revving up but in third i cant even get to 3000 without it feeling like its about to cut off and choke and the triangle with the arrow around it comes on..its a 96 318ti and it just started doing this after i got the new tire..i doubt its bacuse of that but i have no clue.. where should i start |  |  | | 12-30-2010, 05:16 AM | #2 | | Senior Member Join Date: Sep 2007 Location: asdfasdf Posts: 10,002 |
is the new tire on the back and is it the same exact size? if you have different sizes it tricks the computer into thinking the wheel is spinning and cuts your throttle, that's what the triangle light on the dash is, seems odd that it only does it at certain speeds | | | | | 12-30-2010, 05:33 AM | #3 | | Junior Member Join Date: Dec 2010 Location: nj Posts: 14 |
its actually its the front driver side tire..i just drove the car and it doesnt do it frist gear.. alittle in second and third feels like a person who doesnt know how to drive stick...and its not the same exact tire the rest are kuhmo and the new one is like some firestrone most expensive one i could get..because the car got towed to my house and i went to the place across the street because it was closest | | | | | 12-30-2010, 06:02 AM | #4 | | Senior Member Join Date: May 2007 Location: LA, Bellflower, CA Posts: 3,613 |
hmmm, yeah... the ultimate snow blizzard up in the north east coast. bummer, i'm enjoying the sunny days and the rain that comes and goes here in SoCal ... it looks so harsh out there.
anyway, are good of tires do you have in the rears? and have you tride to use the higher gears like 2nd to start off?
or how about using chains? __________________

I suspect the ABS is getting mixed signals from the new front tire. If it is a different size than the other 3, the ABS sees one wheel spinning at a different ratio, and tries to compensate by engaging, thereby slowing the acceleration and overall speed. The faster you go, the greater the variance in overall wheel diameter, and the more the ABS tries to compesate. __________________ James 95 active w/leather interior and sport interior conversion, Vaders, full M-Tech exterior conversion.

Depends on which year his car is and if it has ASC, the ABS is only involved in this type of problem if the car has the ACS throttle body.
Also I've seen snow knock the sensors on some cars around and mess them up.

Make sure to always have the same tire size per axle, in this case your front axle is off and that triggers the ASC (which is suppose to to do that). Good luck and let us know if that fixes your issue. | | | | | 12-30-2010, 07:08 PM | #11 | | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 |

After seeing your tire size it is confirmed this is the issue. John S | | | | | 12-30-2010, 11:25 PM | #12 | | Junior Member Join Date: Dec 2010 Location: nj Posts: 14 |
