MIROZO 234-4668 Oxygen O2 Sensor Upstream Downstream for Chevy, for GMC, for Cadillac, for Buick - Silverado, Suburban, Impala, Sierra, Yukon, Escalade, Lacrosse, Rainier More Vehicles

All GM 3400 engines are a pain in the butt to work on. Pretty much had to roll engine forward to get clearance to work blind to find the O2 sensor.

Bought one of these for my 2004 Buick rendezvous everything matched up perfect.

Difficult to change but not too bad. I had to buy a special cutout socket and heat the old sensor to break it lose. New one fit and is working fine

Installed and code was cleared (previous sensor has the wire cut). Was working for some time and started throwing the codeP1174, every once in a while (checked with the different sensor). Can't return as a time frame for return just closed. Very dissatisfied.

I installed the sensor drove 2 miles and check engine light came back on hooked it up to the computer it was the 02 sensor that I just installed I check my wires took it reinstalled and clear the code’s drove it 2 miles light back on so don’t wasted your money

Stalled my engine, not a good product

This fits my 2007 Silverado vin code O, but had to cut off the connector from the old sensor to work. The price was good, not worth the extra work
