Over the past month or so, I'm having what I've read in other thread described as engine "bucking".
Doesn't happen often but when it does, I have to pull over to the side of the road.
Otherwise, "bucking" occurs. Like an on/off, felt thru the drive shaft.
Engine runs but car is not drive-able.
I'll let it idle for a few minutes (1 to 5), watching the tach surge from 600~800.
As soon as the surge smooths out, all is well and I drive away.
I thought it might be my fuel pump but the more I read here, seems like it could be a cam position sensor problem.
Read on one post here from TbirdSCFan that seemed to describe my issue.
He recommended unplugging the sensor, then starting the engine (which may take longer than normal) and see if the problem persists.
Could use some help troubleshooting this.
I didn't know that shutting off the engine, unplugging the sensor, then re-starting would isolate the issue.
Can I unplug the cam sensor while it's surging without damaging the EEC or other components? Assuming this can be done keeping all fingers attached / away from belts.
I'm willing to shut the car off and unplug the sensor if needed, just trying to prevent getting stranded or needing a tow.
Any other thoughts on this would be appreciated.
Video's below to help describe.
On the highway, I could feel the "Bucking" coming. Let off on gas, pulled over and shot this video of how it surges at idle. If I would have attempted to drive away, bucking would have occurred.
