My 2001 Lexus 430 started running hot (close to hot) on a trip. Seemed the thermostat was stuck, but I was able to drive at 50 miles per hour and the gauge stayed well below the redline. Changed thermostat, but now have "lean" codes for bank 1 and bank 2. Have changed plugs, PCV, air filter, and added fuel cleaners, and cleaned MAC. I can't seem to find any vacuum leaks. Any ideas? Thanks in advance. Joe

May be a front end issue
