Hello all. I am new to the forum and am having stalling issues with a truck I had picked up a couple of months back. The symptom is it will stall once or twice a day while the vehicle is at idle rpm. it can happen while sitting at a traffic light or when I have taken my foot off the pedal and coasting on the freeway. Operating temp does not seem to be a factor. I have replaced the CPS. The one that I pulled out was grey and the eBay one I replaced it with was also grey. This seemed to have no impact on the problem. I have a bluetooth OBDII device with torque that I have attempted to pull any codes off the computer with but it seems the truck stalls when I attempt to pull any codes or reset them. Not sure which direction to go at this point. The truck has 410,000 miles on it but otherwise seems to be running great. Ideas?
