Chrysler Repair: stuttering when accelerating from 50 to 60 mph, plymoth breeze, diagnostic capability

Question
My 1999 plymoth breeze stutters when going from 50 to 60 mph, it feels like it may conk out but it don't and then after hitting 60 mph runs good...

Answer
Hi Sandy,
Fortunately there is on-board diagnostic capability that you can access with your ignition key:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the odometer window on the speedometer to see the mileage change to show a 4-digit number preceded by a P. Let me know what you find and we'll go from there. I suspect one part but let's see what the engine control module thinks is wrong, first. When you send the follow-up question tell me also which size engine (L) is in the car. Thanks
