So I was driving home today and noticed that my truck (99 tacoma 4 cyl 2.7) started stuttering. Then after a little while of this the check engine light started flashing. I now realize that I probably should have stopped right away, however I was in a Nat'l Forest with no cell coverage..so i decided to drive the remaining 10+ miles home. During the drive the flashing cel would come and go, but the stuttering became worse. By the time i limped home, i noticed that the catalytic converter was glowing orange (hoping i didn't do permanent damage??).
From my initial search, it seems as though I am having a misfire problem. I do not have access to a code reader, so I will run out (not in my truck) in the morning to see if autozone will loan me one. I guess I could start by checking plugs/wires. Any suggestions on anything that I can look for to help diagnose the problem??
Thanks in advance
