I just installed underdrive pulleys and an proform electric fan, after I was done I pulled the car out while running and it was fine for about 5-10 mins and it just died. I tried starting and it would struggle to start and would die. I tried so much that it killed my battery, I tried starting the next day and it started running fine again for 5-10 mins and did the same thing without killing the battery,so I replace the battery and battery cables, I checked the alternator to see if it was charging and it is with 13.8 volts when running, so I then checked my codes and it only has one code and its code 81 intake air control, what does this mean and would this cause my problem. Also my temperature of my car gets around 210 and my fan then turns, i'm trying to get the fan to turn on at about 180-185 but I can't. I got the probe between the fins about 4-5 inches away from the upper hose. Do I need to be closer to the hose? Or would this cause my car problems? Thanks:SNSign:
