    Today I started my car after i got out of the store. When i started it and tried to go, it bogged down. Now the sensors to the wheel hubs have been cut for about 6 months now, and the "traction off light", "low tire pressure light", and the "ABS light" have all been on. Today they all went off and the "low trac" light came on. when i take off, it takes off in seconde gear and once it gets going, i dont feel it missfireing any more. it only missfired when taking off. Anyway. so at a red light i decicde to hit the "trac" button, and the "trac off" light came on. when i took off, it was all normal. i have no idea whats going on....anyone have an idea.
    For those of you who dont like to read

    How many miles?
    Recent maintenance (...if...any)?
    Irridium spark plugs last 100k mi and work just as well as copper. Copper is a waste on N/A and only lasts 15k mi. Don't use Platinum.
    Use 195* tstat unless you can thoroughly explain why not; 99.9% don't need a lower temp.
    Almost any oil filter, ever, is of higher quality than ACDelco. Spend $6+.

    187k. plugs wires, fuel filter, air filter.
    the problem is that it thinks the wheel are spinning when they are not, so it cuts the timing and bogs down. but when i turn the traction control off, it is fine.

    Cat is good for 150k. Smell eggs? Just sayin'.

    But, uh? You don't feel like putting new wheel hubs on? There's a tutorial around here somewheres for how to hack something to keep Trac off.

    i can put new wheel hubs on....just dont see the point in spending 2 hundred bucks. The trac alwasy used to be off until today..thats what i dont get. the tractiong control came back on and is thinking the wheels are spinning, there for it is bogging the motor down.

    My car you have to turn off traction control each time you restart the car. If you dont want to fix it then just shut it off each time

    lets restart

    Everything was good until today. I have been driving around with no ABS and TRAC light for 6months....no problems then

    now today the Traction control came back on.....and the LOW TRACTION light is on now also....hence why it is bogging down.

    My question is why would the Traction control turn back when the wiring is unplugged at the wheel hubs.
