so on my 2004 2.2l cavi ls when you crank it up everything is ok. but when you drive off it will shudder like its struggling to move sometimes... and also it will sometimes say i have low trac and the trac control system comes on, but it always down the road The ABS light will come on and my Trac Off light comes on.... any suggestion .pls
5 spd or auto? If it's a 5 spd, it sounds like your clutch may be giving out as far as the shuddering goes, dunno on that. But as for your ABS light and Trac Off light, it's usually the wheel hub speed sensor, they are in a really crummy place on the hub assembly on the back, I'm in MN and I have to do mine about every other winter because they get packed with snow and junk and freak out. I'd start there, that's what it sounds like to me.
