Here goes my problem. My 2001 LESXUS ES 300 started to rough idle and
vibrate at low speed and it feels like I am driving over a rough road. I
changed all the 6 spark plugs but was still behaving the same.. I got it
scanned and got these codes P0300, P0302, P0304, P0306, P1354, P1155….. After
reading through many Lexus forums I changed the OCV on bank 2 closest to the
radiator which took care of the ruff idling and all the codes except P1155… After reading again I now decide to change
the Oxygen sensor before the catalytic at the front of car. I am very hesitant
because that Cat is getting RED HOT after about 2 miles of driving…..My
question is what do you think I should do???? Don’t want to buy Oxygen sensor
and damage it with red cat or do you think it’s the sensor causing the catalytic
converter to glow red?????HELPP

VVTI solenoid, or alternate name, Oil control valve.

~100$ ea, aftermarket, about 10 minutes to change both [recommended, highly].
