type.r Posted August 9, 2012 Share Posted August 9, 2012 hi guys!!! I'm Andrew from spain, I own here a litle garage and I'm trying to help a friend with a rx300. His problem is exactly the same one as explained on this topic http://us.lexusownersclub.com/forums/index.php?showtopic=73439 The car has been 2 months on the lexus being repaired and after paying 2.500$ car is just on the same way as when it got into lexus. New auto gearbox Every O2 sensors are new All spark plugs. all ignition coil ( is this the proper way to say the things that are attached on the spark plugs?) Both catalytic where smashed by the heat so theyre new. MAF is new... We dont know what more to look at, have anybody ever changed nozzles on this cars? from lexus spain they say they dont know whats the problem. just a litle comment, car has receibed gas instalation and drives awesome... problem only comes with RON. Really thanked for any help Sayonara! Quote Link to comment Share on other sites More sharing options...
