Check engine light on

You need to start by getting the codes, then we can proceed.

This guide will help us

First thing is to quit believing every thin you read a lot of these people are quacks. Then go to an auto parts and get it scanned for codes they do it for free then get back with the code to us do not have auto parts sell you any parts. If you drop a valve seat you can pretty much kiss the engine goodbye, but get us the code first. If it is a misfire code then go see a mechanic misfire codes are 0300-0304 because it can be anything. But if not get us the code.

Is this a natural gas powered car? If not these are what to look for in picture. If it is an O2 sensor number one is before converter two after converter. See picture.

Hello,

Ok, there are a few things that can cause the code you are getting.

40) For Continuous Memory Only DTCs P1130, P1150, & For KOER & Continuous Memory DTCs P1131, P1132, P1151, P1152, P2195, P2196, P2197 Or P2198: Upstream HO2S Not SwitchingContinuous Memory DTCs P1130 and P1150 indicate when an HO2S fails to switch due to a circuit or fuel at or exceeding a calibrated limit. KOER and Continuous Memory DTCs P1131, P1132, P1151, P1152, P2195, P2196, P2197 and P2198 indicate a concern when fuel control system does not detect HO2S switching for a calibrated time. DTCs P1130, P1131, P1132, P2195 and P2196 refer to HO2S-11. DTCs P1150, P1151, P1152, P2197 and P2198 refer to HO2S-21. Possible causes for these faults are:

Fuel System - Excessive fuel pressure, leaking or contaminated fuel injectors, leaking fuel pressure regulator, low fuel pressure or engine running out of fuel or vapory recovery system fault.

Induction System - Air leaks after MAF sensor, vacuum leaks, PCV system or improperly seated engine oil dipstick.

EGR System - Leaking gasket, stuck EGR valve or leaking diaphragm or EVR.

Engine Mechanical - Engine oil overfilled, cam timing, cylinder compression or exhaust leaks before or near HO2S.

Also, I would check for a burnt fuse, since the O2 Sensor is Heated it requires a fuse.

As far as the Advise from AutoZone - they are only reading what the Code Def is and not what other conditions can cause the code and they would love to sell you an O2 Sensor that you may or may not need.

As for the Herko Automotive Group I honestly haven't heard of them, so cannot say.

The only way someone can help you on this website is if you tell us what the trouble code(s) is/are.
Go to an autopart store like autozone; they can scan your car and retrieve the trouble code(s) for free.
Once you have the code(s), post back with them and we'll start from there.

Ignition System
Faulty Evaporative Emission System
EGR &/Or PCV System
Air Intake System
Engine Oil Contamination
Fuel System
Exhaust System Leaks Or Restriction
Engine Cooling System
check all that first including checking air intake for holes and check O2 sensor for a broken wire.

Why are you so confident that component is the cause of the code? There are 22 pages of tests to resolve that code.

Hi amckey,Welcome to 2carpros and Ty for the donation.

Start by checking the spark plug,compression and fuel injector on #2 cylinder.
