Just tying to find out whats wrong with my car, I think it my be my o2, because while I'm driving my car it looses power for just a second and comes back to life.

It does it most when it's cold but its also done it when its warmed up. I have also noticed that my car feels like it wants to die at idle I've cleaned my IAC and it seams a little better, but it's still not %100.

You could always just pull the front ones out, and use a wire brush to clean the deposits and crap off them, pop them back in and see if it makes a difference. At least it would give you an idea what sort of shape they're in.

I would think your car would run rich if the o2's were bad. I may be off hear but I think the system is desined to just run a rich limp mode if the o2's are not working correctly. someone with more knowlege will hopefully chime in.

I Think Most Of The Time If The O2's Are Not Working Right You'll Get A Check Engine Light. When Mine Was Runnning Really Fat It Would Trip The Light.
