Hey That is great to read. I had my 2001 IS200 converted 3 years ago. Had huge problems with stalling eventually always when cold, plus big loss of power, and last year they fitted new valves and valve seats, which in addition to fitting 6 new coil packs, due to incorrect diagnosis of the stalling problem cost me the thick end of £3000. I therefore thought I was being super cautious when I took the car in again yesterday, but sure enough there is wear on at least 2 valves....they are now doing the repair under warranty, and fitting a FLASH LUBE KIT. It is great to know that yours has done nearly 90,000 miles since the flash lube installation. The problem on mine got chronic probably after around 20,000 miles. I was thinking I would have to get rid.

Just taken the IS200 in again to the LPG garage, and there is valve wear again, one year on from strengthened valve seats and new valves. They are going to repair the damage and fit a flash lube kit. I would be interested to hear of anyone running an IS200 long term on LPG, and know the secret of their success. Also I have heard that if you run 20% of the time on Petrol that this is helpful but surely if there is a problem, then that is only going to delay the problem by 20%, or am I missing something?

Hi I have has the same problem with my 2002 model IS 200 SE. Ran pretty well for the first year, though there were problems with stalling when engine cold. Finally diagnosed 2 years and 50,000 after LPG conversion. £2500 repair job. New valves hardened seats & still not sorted. phil E.
