Love My Lexy!

No! It more than likely the ignition coil. Auto zone shot out the same thing on mine and they said computer was bad...etc But I had a code P0301 which was ignition coil one was bad. Did mine 2 weeks ago no problems since had to have the light cut off but it has not returned yet have drove over 1500 miles since! It only cost 75.00 for the coil.

I have a RX 350 and drove on Carrolla 4×4 beach NC  in June it was awesome even though people looked at me like I was crazy! It drove fine didnt get stuck like some trucks I saw at the entrance! I do have a AWD as well.

Sam...the plugs were fine. It was a bad ignition coil. See my post above :)

Did you have like a rumble feel when you where going down the road?

That is weird, would love to see what codes you have. Missfiring on all is not usual. That is why We like to see all codes. The code will tell us which coil, if it is a front of engine one it is a piece of cake to replace, the rears are on the other hand not easy....Replacing that coil, and reset the codes and see what happens. As for plugs, just don't believe it. Unless somebody else changed the plugs and put something other than iridium Denso or NGK plugs in. That is another story. Never use plugs other than the iridium NGK or Denso. They last a long time. Mine have 144k miles and they look great.

Mine to did the same thing today all misfires!
