Almost two years ago when the ck engine and trac off lights came on my 1999 Lexus ES300 had a hesitation problem that went from bad to worse in a short amt of time to finally the car could only be driven to the repair shop and they replaced an oxygen sensor which took care of it until now when it started all over again. They recently replaced some other kind of sensor located in the rear of the engine but it did not fix the problem. Even though the car was on the diagnostic machine for hours it still doesn't pinpoint the real problem. The quick diagnosis at Autozone showed the Fuel system problem (code 1354 I think). I told the repair shop this but that didn't seem to help. The new thing it is now doing is the brake (not the ABS) light keeps coming on and off. Is this a related problem?
