transaxle input speed sensor
 

Hi Everybody,
I have a 1993 sts - I love it- but the engine is is running rough- I checked and found a p056 code and a p132 code. The p056 is the transaxle input speed sensor-would that cause the rough running or possibly the p132-knox sensor problem or both? My mileage has slipped from 16.2mph to 14.5mph. Or is there anything that could cause false readings?Any help would be greatly appreciated.
Thanks!
