I have a 99 RX300 that recently had a CEL and I had autozone read the code to be p1349. The CEL disappeared when I re-started immediately after reading the code. The RX was sputtering a little at acceleration before the CEL reading, but I do not notice it now. Could this be a one off or am I looking at something going bad with an intermittent CEL?

 

Remember the code and see if it come back. Make repairs when the code comes on the second time.
