so recently on my g35 ill be driving down the freeway and the car will jerk, loose power, then jerk again, and after the second time it does that, the vdc off and slip light come on and stay on, it also throws a CEL, but after 6 hours or so ill turn the car on and the CEL will still be on but the other lights will be off and the car will run fine, seeing as i don't know too much about cars and i don't own an obdII me and my friend are thinking that its a bad speed sensor, and that the jerk that happens is from the car thinking its breaking traction and cutting fuel, also when this happens and i turn the car off and start it, it cranks forever and takes a while to turn over, im thinking this is also cause its cutting fuel, but with a speed sensor wouldn't i loose my abs? anyway i can't find too much on this issue so most of this info i just put together myself, can anyone give me some help on this ? appreciate it thanks, and i appologize in advance if this is in the wrong forum.
