well my service engine light has been on for about 2 months i finally went to the shop and had a diagnostic run on the computer for the problem codes. I found out that all my O2 sensors were going out. and i work in the oil field so im on the road frequently traveling long distances. Now just today my truck started to kinda bogg down slightly when i was accelerating slowly so i hit the gas and reved the RPM up to about4500 rpm's and my truck started to squeal after i dropped back the RPM and released the gas some so as to regulate my RPM the squeal immideatly stopped. What could be the cause for this? also my service engine light is starting to flash, what can this indicate? Please Help.
