CHECK ENGINE LIGHT

1999 Lexus RX 300

Engine Mechanical problem
1999 Lexus RX 300 6 cyl Two Wheel Drive Automatic 84000 miles

My car was sluggish, hesitating and backfiring. I went to Autozone prior to dropping off the car. The computer codes pulled were P0125, P1135, P1150 and P1155. What steps would your guys do to service the car?

Also, is an engine code P1185 a valid code for a Lexus?

Checking fuses would be my 1st step.
Is the engine warming up to operating temp nice and quick
check thermostat and its operation
O2 sensor most likely at fault if all checking out OK
I am not sure of o1185 I will try and research it and let you know if I come up with any

Yep was code a disreputable service station said was the reason he replaced a fuel pump. Wish I'd checked here first before going but sometimes in an emergency you do things out of order
