My Ranger has started to stutter violently and occasionally stall out at around 2k rpms while in drive. It doesn't happen when in park and I rev it up to 2k rpms. It happens in any gear while in drive. It also seems to be related to the weather but I have no confirmation on that. I can pull it out of the stutter most times by flooring it.
I'm not really sure where to start on this one. Couple things I was thinking:
O2 sensor (changed this and still does it) Throttle position sensor.
- Timing a little off. (maybe one or two teeth off?)
I just changed all of the spark plugs and re-gapped them to .044in
Any ideas before I start tearing it apart?
