Not sure if this is a coincidence or something major. I'm sitting at a traffic light yesterday and my truck starts skipping and ac starts blowing hot air at them same time. At first the skip is not so bad but the closer I got to the house the worst it got until it died before getting home. I get it home run the codes and have no cop ground on 5 cylinders. I've ordered 8 new cop pigtails so this should be fixed. I've tried jumping the low pressure switch on the compressor but it still won't kick on. Could I have an ecm problem or other electronic problem. Or did the cop pigtails and compressor just quit and them same time? 2005 f150 5.4 233,000 miles plugs December 2013, COP March 2014
