Hi, new here, First Lexus, have 2 questions, left side downstream o2 censor disconnect plug location? Just bought this car from second owner. He had for 21 years, have receipts for 32,000.00 in repair and maintenance from Lexus dealer over the years, yes.OMG I had missing issue, running on 4 cylinders.found rt. Rotor ground to pieces. Replaced rotor and cap, did it againin only in few hours use.New t belt, camshaft seals, cam bolt tight, WTF? Thanks for any help.

 

The carpet has to be pulled up to locate the connector for the o2 sensor.. as for the other issue look to see if the main bolt is losse that hoids the cam gear on. make sure you bought oem parts too the cheap knock off can be ****.

 

Thanks java, any idea what area to remove carpet on driver's side downstream o2 connector? It turned out to be left side rotor and cap failure this time. I talked to Lexus, he said simply fatigue. Used to change a lot of them being ground up!
