    engine stopped while driving on highway, inside temp not right

    HI

    the engine of my fleetwood 88 4.5 stopped yesterday while I was driving on the highway. After restarting in P the engine runs again but stopped after a while again. After waiting for 1 hour I started again and it ran. CODE E32 has been shown form the first time. First I thought it could be the fuel pump. But I don't know...the manual says that the VCC could be wrong?!
    Another problem is my inside thermistor is not showing the right inside temperature. It is always showing 40 - 50F more than it is in the car. That's why it starts cooling, so it's always cooler in the car than desired. Yesterday I had to choose 85F!!!!! to get a nice temperature in the car and it was 75F outside. The BCM showed 91F inside temperature!!! I mean that's simply not right.
    I got R134 in my AC. I retrofitted it one or two years ago. It's cooling and heating fine. But not in the right temperature area. I have a second inside thermistor I replaced it and nothing changed. Some one told me that the AC will not work right when you got R134 inside. But this has nothing to do with the fact that the inside temperature is not showing right.?!?! HELP!

    E32 is an Open MAP sensor circuit. No other E codes? No F codes? F13 is the In-Car Temp sensor circuit code. Check to see if the aspirator is able to draw in-car air past the sensor. I converted my system to R134 10+yrs ago and have had no AC problems of any kind....

    Thanks.I will check that. My AC works fine. Only one thing is bad. When I got
    about 12C outside the AC Service light comes on. But only within these temperatures. By erasing the codes everything works fine again.
    By the way...no other codes, no E codes, no F codes.
