In addition, I replaced all three sensors and the four gaskets. These were OEM Toyota parts, the same parts (part numbers) used on the Lexus.

So far, things are good. The car's performance has picked up, and the check-engine lights are off.

I must say that the gentleman at DEC, Derrick, gave me plenty of information over the phone. He actually told me if a part was not in stock, he'd make it and ship it the next day.

The folks at Wunderparts, Brad, Cisco, and Ryan, were very helpful and professional. Plus, the prices were very fair.

Best,
