jevanof Posted September 28, 2012 Share Posted September 28, 2012 Hello I have a 99 RX300 and the check engine light was flashing on my way home from work, here are the codes that I am receiving. P0300 P0301 P0302 P0303 P0304 P0305 P0171 P0136 I cleared the codes and all 12 came back Any suggestions other than take it to a shop would be greatly appreciated.

lenore Posted November 3, 2012 Share Posted November 3, 2012 you may have some bad coil packs...time to do some swapping and see if the codes change. Quote Link to comment Share on other sites More sharing options...
