600 Hiccups

[Gilbert Fudpucker]

LS600h , not that often used but , this afternoon took her out & switched to Sport mode and Power , went for a spirited drive as the hacks would say ,  it put a huge smile across my mush , but at around 40mph ,  I noticed what I can only describe as engine hiccups , almost a misfire as I was on a flat straight road between a trailing throttle and accelerating gently 

Could this be the electronics switching between Hybrid and Engine mode & not sure which to engage ?? , never noticed it before as I always drive in the "Old man mode" , has any other LS owner experienced this 

I'll take it in and get Lexus to check it out but it had a clean bill of health only a month ago by them , bit odd don't think it was my right foot

To think I almost bought a Bentley , I must have been mad , in my humble opinion the LS is a much more rewarding drive with lots more toys

I've got a 2011 also (and live not too far from you - Newcastle Actually Gilbert Fudpucker) - watch out for 2011 Black LS600h L.....

 

As for your problems - could be dirty fuel, could be something blocked - a fuel filter perhaps? I would give her a good run on the motorway. and see if it gets better/worse or stays the same. Did you get any dash lights or warnings - might be worth sticking it on an OBDC scanner or taking it to Lexus to see if any fault codes stored etc.

Best of luck - let us know how you get on...

Thanks for your thoughts , dirty fuel , hmm certainly not a filter as all changed recently and no dash warnings at all , possible a jolly good blast would do the trick but i'll drop it into Lexus for a check , never happens on my RX450h which made me wonder , but there again the RX doesn't have the Power mode option let alone all the extra horses

Never know we may pass each other on the A1 !!

Do you guys put the standard 95 petrol in your LS600h or do you use the higher grade (can't remember what it is called) 97 (?) fuel?
