    So the last couple of days I've been riding the '07 green car the one that has the bad brake actuator the beeping going on and other than that drives like a dream no codes other than for the low accumulator pressure and the sensor that's inside of the thing I can't remember the name of it right now I have the codes for that they're going to be there till I change the actuator again. But I've noticed when I'm driving under light load say 45 mph with the cruise on or off it feels like the traction control or the vehicle skid control is messing with the system It's kind of like when I have the wrong size tire on one wheel in the '09 The skid control light to the left of the exclamation point would light up when I was trying to speed up and it would keep the car from speeding up because it's doing something to try and stop skidding or something. Well this green car feels like it's doing that but it'll let me get up to speed actually when I get over 55 miles an hour to 75 the car drives like a dream with the cruise on the highway when I get back into town 45 miles an hour just cruising it feels like the skid control is trying to make adjustments I actually saw the skid control lamp flash for an instant this morning just for a second I haven't seen it do it in this car ever except this morning. And that's what leads me to believe the feeling that I'm feeling is the skid or traction control trying to compensate for something. And I'm asking could my break actuator that's failing or failed or whatever caused the skid control to want to activate because there's nothing on the road to be causing it the road is clear nice Sun is out etc. But when I had this problem before in the '09 the skid control would barely let me get to 55 miles an hour and the light would come on and off as of the skid control would operate here I'm not seeing the light but I'm feeling the feeling and it's just kind of weird.

    If I were you I'd do lots of reading on here regarding skid control symptoms...

    Yeah I'm looking at that and seeing of the last two or three cars that we've done this with nothing like this ever went on and we've had a couple that were worse so I just find it odd that all of a sudden out of nowhere maybe the cold has more to do with it than just the ABS actuator because it seems like nothing's being called upper really happening. I'm also thinking I replaced the front hubs on this car quieted the car up quite a bit It does need the rears done and they're sitting here ready to go it'll be 60 something degrees Wednesday I'll probably slap them in I was just wondering if maybe because there noisy and weird maybe one of the rear hubs is kind of not doing its thing correctly and sending the wrong signal to whatever it sends signals to The VSC traction control computer whatever it is I have an unplugged them to see if any of that could be because then I figure it'll just get worse. When I take the hubs off the back I'm going to break gently the plastic cap where the plug goes so I can actually see behind the plastic cap and see maybe what's damaged what goes on in there I don't hear any noise in them other than the groaning whining that they make nothing's bouncing around inside of them or anything like that and the fact that it doesn't do it when I'm going down the highway which I ride more the last few days then in town going down the highway at 74 miles an hour the car is flawless doesn't do anything but go good ..well whatever. And the other cars when the skid control attraction control was acting up because of wrong sized tires that was a fact The car would not allow practically me to get to 60 miles an hour The car was speaking of now has no trouble getting to 75 this is only happening between like 35 and 50 mph then it's gone.
