It could be your catylitic converter, well one of them or all of them the Concorde has three!!!
You have a misfire, see question linked below.
Are you talking about when it blinks at 85 mph? It actually is still accelerating, it only blinks because the speedometer only goes up to 85. It's not a governor, it's the speedometer.
Either with a scan tool or by turning key on,off,on,off,on and counting the blinks.
Have it checked for codes to know possible causes.
Susan Blinks was born in 1957.
I do not have the exact URL for the page, but I know I have seen them posted on allpar dot com (huge site, nothing but Dodge/Chrysler vehicles,repairs,info, etc. with a specific section on minivans. You might already know this , but I post it anyway. To see the codes displayed, You insert key, turn on to accessories (not start engine), turn off, turn on, turn off, then turn to on again and left it in that position. In a few seconds, you will see a cycle of "blinks" begin on the dash display, (left side of steering column in my 90' Grand Caravan). The code format is displayed in pairs. Example: one blink, short pause, three blinks = Code 13 longer pause Example: two blinks, short pause, five blinks = Code 25 End of cycle is always displayed last as five blinks, short pause, five blinks I guess this code display is on many cars other that Chrysler/Dodge (Fords)
With a scan tool, at a parts store (ie Autozone does it for free), or possibly by cycling ignition key on, off, on, off, on and counting the blinks.
An owl blinks one eye at a time
It's a control in your car that that blinks all four turn signals at the same time. It's used to signal other drivers that you are driving excessively slowly (or your are stopped where you shouldn't be stopped), or to warn them that there is some hazard in the road.
