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.

If your coils are mounted directly to the plug, try swapping coils between cylinders to see if the problem shifts to a different cylinder.

I have a knocking sound from my left rear wheel as
Hi, The first thing to do is take off the hub caps & see if one or more wheel nuts have come off! If that is not the answer then check if one of the brake pads has come adrift. The only thing easy left is the wheel bearing, should that not solved then you have a half shaft problem and you need to take that out look at the teeth on part that goes into the Diff the teeth should be straight if not then you need new half shaft & if one has gone you can be assured so has the opposite wheels well on they way to going or your Diff needs renewing & thats expensive. Please leave me feed back: Malcolm Campbell, Thanks.
