Need DTC (CODES) Help

[MiBuick]

My 96 buick 3.8 lesabre runs rough as soon as it reaches operating temp. If I shut the engine off for a minute and restart it it runs great. I had the codes tested and come up with a code "PO108 map/baro Circuit High Input" and a code "PO117 Engine Coolant Temp circuit Low Input" Can someone tell me which sensor I need to change and where I can find that sensor on my engine. Also I do have a complete 92 model for parts if they will work. Any input will be greatfully appreciated. Thanks , Bruce

P0108 code- Check the o-ring on the sensor to make sure it is in good shape if not replace it and check if code returns before replacing MAP Sensor. IT is located on the Upper Intake Manifold front passenger side. Look at this thread it shows the location:

Make sure you read the thread well and click on the CLICK HERE and read it carefully so you don't accidentally break something.

P0117 code- Make sure you do not have a coolant leak in the engine. According to the manual I have looked at the ECT is located on the left bank side of the engine block towards the tranny. (Clyinder head nearest to radiator)

Send me a Private messsage and I can send you more info where the sensor is located that will be a help to you.

Hope this helps
