I went to work today with no issues, went and sat in my truck for lunch with it running with the A/C cranked after 10min the CEL light came on and every so often the truck seem to have a small lope in the idle, drove it home and it seems to have a small stutter and alittle more smoke than normal when booking it on the freeway but otherwise runs fine, about 5min from home the light went away, pulled the code anyway and the only code was po093 and im having trouble finding what it is. thanks in advance
