2007 lexus rx350 ,vsc light on and check engine light is flashing
First check and make sure your gas cap is tight, if this does not resolve the problem read below.
A vacuum hose has become disconnected, more than likely due to having your air filter replaced. The VSC and Check engine light typically don't come on until after 150-200 miles after the vacuum hose was pulled out.
The fix: on the right-hand-side of the engine compartment behind the big plastic housing that holds the air filter you will find a black rubber hose that is not connected to anything. Squeeze the finger clamp on the hose and slide the hose back onto the half inch nipple on the back of the air filter's plastic housing.
In order for the VSC and Check engine light to be turned off, you will need to open the fuse box, right-side of the engine compartment, and pull the 20 amp EFI fuse for 10 seconds. This will reset the system. The fuse location is marked on the lid of the fuse box, also I believe the EFI fuse is the only 20 amp fuse
. This will help. Thanks, please keep updated. please do rate

My lexus rx300 reads codes p0171 and p0174 system
The injectors on that side maybe clogging up a bit,try a good fuel injector cleaner such as ,LUCAS fuel treatment,use it with as less fuel as possible,it will clean better,there most likely is a restriction on the fuel spray on the injectors,have the fuel pressure regulator checked,it may be passing too much fuel back to the tank.

RX300 2003 1MZ V6 engine engine hunting when hot n dies off
There isn't just one cause for this symptom. Is the engine light on while it is running? If so, please have the codes read and forward them. My first guess for "Hunting" is timing. The timing belt may be loose or the crankshaft sprocket could be loose. There could also be an electrical issue with the fuel system, ignition system or a component related to the ECM. Please write back with more diagnostic information and I will do my best to help.
