On mornings of fog recently, moisture on everything, our 97 T&C (179,000 miles) will run rough and even stall until it warms up ( minute or two ).

We replaced plug wires once before, do you suppose that is the fix for this or could it be something else?

Seems to run fine once warmed up.

thanks.

 

The plug wires are the first thing I would check or replace.

 

no code? CEL?

 

When its running rough bring the van into somwhere that is dark. And look under the hood at the wires. If you see sparks jumping then you need wires.

 

No error codes; and after running a minute it seems fine.

Problem is it's never dark at the time ...

thanks
