Hi Everyone,
I'm confused. A few weeks ago, my car started this weird problem. I was on the road for about 1 1/2 hours when my car started surging under acceleration. At first, it occured under high RPMs. I stopped and couldn't figure anything out. As I continued, the problem gradually started occuring at lower and lower RPMs. I stopped driving for about an hour and the problem stopped.
I drove around town for another two weeks for short trips and the problem never reoccurred. I drove from Louisiana to Missouri and the problem came back. It got so bad that I had problems going up hills. I took it to a dealership and they replaced my O2 Position 1 sensor. Problem still occurred after an hour of driving.
Here is what I've noticed so far.
1) The problem only occurs after an hour of steady driving.
2) The problem discontinues when I turn the car off for an hour or more.
3) The "surging" feels like when traction control or speed governor comes into play.
My thoughts: I think there is some part that when it heats up, it causes slippage. When it cools, it acts fine.
Anyone have a similar situation?
Thanks,
Timothy
