Good day all! I've got a 2000 Taurus with about 125K. Over the last couple of weeks, I've noticed that when I climb a large hill (daily)with cruise set at 55/60 the car has a "mushy or miss" accelaration. Also, after I feel it the rpms increase to meet the demand of the climbthe "mushy/miss" acceleration is gone. It reurns when the rpms level out again. Today I encountered it again and half way up thye hill, the check engine light started flashing and keptflashing until I leveled out. Went out ans stayed out for the rest of the trip. Otherwise, the car works as advertised. Recent maint: oil change, fuel filter, egr/pcv valve/sensor.

I'm not the sharpest bulb on the tree but could it be the plugs/wires or transmission slipping. I'm not the first owner so I don't know if there was a tuneup done.

Any point in the right direction is appreciated.

check your vacum lines to see if one is bad or put a vac gauge on and check vac. kinda sounds like a possible bad vac.

 

If the CEL came on and was flashing, there is a code stored. Get a scan and post the codes here.
