Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.
1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..
2. Amazon.com has the code reader for less than $20.00 dollars.
3.Re-post the dtc's in here " answer question " for further assistance.
Note: we need the dtc's to identify the sensor, there are a dozen different sensors to operate the car.
Visit this site and see all the different sensors.
Navigate to this site and see the code reader
Note: The sensor is threaded into the exhaust manifold.
It can be difficult to remove unless a special anti-seize compound is coated onto its threads.
Torque the sensor to 30 foot-pounds using a special socket.
A sensor that is too loose or a cracked exhaust manifold can result in a lean signal to the computer.
Check the vents in the thimble of a replacement O2 sensor.
There should be the same number of holes and they should face clockwise or counterclockwise like the ones on the original sensor.
Installing the wrong sensor can result in slower cross counts.
