Hi guys/girls, Managed to buy a bargain lexus IS250 Petrol Automatic 2005 with 112k miles on it. I've been wanting this car for long time and just couldn't hold back from buying this. After driving for few days the engine management sign came up. RAC did a diagnostic test and came with attached codes. Any idea if I change both banks will problems be finished or is this something to do with the timing change . It's a V6 so labour would be over a grand not something I want to fork out at this moment. Any help will be much appreciated coz can't afford more hiccups .
