Took it to the local auto parts store they checked codes but only stated that it was the rear bank but, didn't know of what. So I changed all the wires, plugs and the Ignition Coils light went out for a few days then came back on. A friend suggested that I replace the fuel injectors and/or the O2 sensors. Any other suggestions?

Re: Check engine light on.
Before replacing all those expensive parts---should hve it scanned by a professional shop. using the generic OBD scanners can give false info sometimes. once you get that code that will be more helpful. i have seen on the gm products especially the newer ones that 1--the upstream o2 sensor failure or 2 --- egr valve issues---let me know what you find out, then ill have a better idea on how to help you further

Code 1150 for a Lexus means the O2 sensor for bank two sensor one is not working. It could be a problem with the sensor or the wiring harness. Bank two is on the side of the engine with cylinder two, and sensor one is in front of the catalytic converter.
unless you do something to fix the problem , it will come up again
the sensor at fault will be the heated oxygen sensor(HO2S)in the exhaust manifold in bank one
It reports the gas composition to the ECM which then adjusts the air/fuel mixture to correct the lean burn
check light means your vechicle computer has detect problem in engine control system you could have bad sensor,cylinder misfire or evap leak like missing gas cap or loose gas cap or fault in the emission control take vechicle to any auto parts stores like pep boys , auto zone, advance auto parts or auto parts stores in your home town. they will code scan vechicle for free and see what causing check engine light to flash on.
You need an OBD II code reader or in some states the local auto parts stores will retireve the code(s) for you. retrieving the code(s) will tell you what is wrong and then you can figure out the best repair.
Hi, the check engine light will require you to have the engine CPU scanned for trouble code's. This can only be administered with the assistance of a diagnostic computer scan tool OBD II. You can purchase this tool, at your local auto parts store, or you can just have the scan ran at your local auto zone parts store, free of charge. Once the diagnostic scan is administered, you will be able to isolate the issues that have caused the check engine light. This scan tool will display a print out code and the location of the issue, on the engine, as well. There are Many issues that will cause the engine light to illuminate, but the most common cause will be a failed monitoring sensor, or sensor harness failure(separated power wire, or ground). After retrieving the code, it will be interpreted to know what caused the lights to come up and that will be used to fix the problem.
All auto parts store have been slapped for perfoming this service. I code does not indicate a defective part which is all the parts store can sell you. Alot of times the code will only suggest that something is affecting the signal to the computer. This is why a diagnoses is important. If the shop just read the code and did not diagnose then you or they may just be throwing parts at this.
Bottom line. Find a repair shop you can trust. Cars cost money to maintain. If your looking for cheap way out you could be costing more money in the long run. With a bad 02 sensor you are stressing the catalytic converter to the point it is getting worn out fast. When it wears out enough it will set a code and you will have to spend hundreds to replace it.
Bank 2 is the passenger side. Sensor two is the one closest to the rear of the vehicle, or "down stream" oxygen sensor. If you are uncertain, then unplug the one you think is the problem, and see if another code comes up. If no other codes come up, then you have the correct one.
