OK went and tested as wwest suggested with the cruise ON....interesting the pulsing goes away? This suggests it's not an engine problem but a computer issue. My original post was moved to this long established thread and it looks like this is a problem reported by others. So the car is headed to the shop Thursday for diagnois and most likely a computer software upgrade. Any other insight and experience with this issue would be appreciated.

Did anyone catch the story on CNN about the doctors rx400h exploding in his driveway critically injuring him and also injuring 2 others? Just happened today. ATF and FBI do not suspect foul play. I'm sure lexus has a "team" on the way as well. Scary... Replies to this message: upstatedoc (Feb 05, 2009 6:59 am)
