Hi, I have Lexus gs300 1997 (2JZGE) Sydney Australia, I have converted my car to LPG, now the problem is backfiring. Every time it backfire, it breaks a big plastic part which is part of air intake, as a result the airmeter does not work and car does not work on petrol but on LPG, it works fine.
I already have change the plug and wire with Lexus Genuine.
Please advice me what to do.
Thanks
