My vehicle started running bad sometimes. Let it sit and start it later and it would run good for awhile but start to run like it is running out of gas and rough then stall and not start. Started running bad quicker every time until it only stays running for a few minute's before stalling and will not start. The dealer said it was stretched timing chains. I took the engine out and took it apart enough to see the cam shafts and the actuators. Dual over head cam. I took the plugs out and noticed the driver side plugs were fairly white. I took out the other side and they looked like that side had been running rich or not firing at all (slightly black). I used a socket to turn the engine over. The four actuators and cams would turn, but at a point the driver side intake cam shaft and cam sensor ring would stop turning. The other three cams would keep turning. It would then get to a point were the one that was not turning would start turning fast as if to catch up to were it should have been if it would not have stopped. Is this a problem or are the other three actuators a problem or are they all good and the timing chains need replacing? They seem to work with oil pressure is what I got from one of your articles. Any light you could shed on this would be great.
have the same problem?
