the po300 code is for a cylinder misfire, usually followed by a last number of 1 2 3 ect, showing which cylinder is misfiring, normally this can be fixed by installing a new set of plugs, the po171 code could be this

• The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
• There could be a vacuum leak downstream of the MAF sensor. you cleaned that but it could be fouling out you could also have this happening
• • Inspect all vacuum and PCV hoses, replace if necessary
  • Check for a dirty fuel filter and proper fuel pressure

The idle issue is normal. The idle is controlled by the ECU. There are no adjustments for the idle. Regarding the knocking noise, that could be several things, and I am hesitant to comment without hearing it. Take it to a Toyota Dealer & have a tech listen to it. We are very good at identifying noises on the service drive.

Is the check engine light on? Check your trouble codes. PO171 would indicate a leaky intake manifold gasket. The gasket between the throttle body and the manifold is also a known issue on these engines. That will cause the engine to cut out or die when the fuel pedal is pressed. parts.olathetoyota.com/toyota-engine-trouble-codes

Did u ever figure it out ? Mine are doing same thing only work during the day and shut off when I turn lights on and don't work at night. I've changed all fuses and relays, still doing the same thing. I'm hoping it's not wiring issue

The most common cause is something inside the glove box jammed in the latch. Push glove box door release , and GENTLY insert a flat putty knife, plastic knife, or similar type tool in the groove of door, GENTLY try to pry open the door. U will probably (hopefully) find a napkin, map, or glove (does anybody actually put gloves in the glove box?) jammed in the inside latch. Let me know how u make out.

you can get guide from many sites.. i know few error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine info, switches functioning, assemble, disassembly, complete refurbish, repair, installation every single thing is covered

Lift up on the front edge of the seat part and slide it out. Next, remove the bolts that hold the back in place. It will pop right out.

the only thing that can make it backfire is a malfunction in the fire to the engine could be coil plugs distributor cap or rotor make sure you check your timing with a light and check codes if any showing

it is usually mounted on to the top of the fuel tank accessible from under the back seat good luck

something heating up try coils or check the crankshaft and camshaft sensors

Check fuse and relay

plugs, coils check also add some fuel injector cleaner to your tank

I think there is try looking under the dash on the passenger side of car or try contacting ttoyota and ask them where it is

It doesn't have a fuel filter there is a screen on the fuel pump that is located inside the gas tank

Usually caused by vacuum leaks. You can test the tps. Remove the connector and check resistance with an ohmmeter. Resistance should change smoothly as you open the throttle. Do It Yourself Diagnosis and Repair

No , it is not a problem. There will be no fire. Just crack your window open just a bit but fix it as soon as you can. Did a mechanic fix it then told you that the front pipe fell off due to rusted bolts? If they broke it, they have to fix it. And they cannot charge you for it either. It wouldn't have fallen if they had done the job right and replaced those bolts before releasing the car back to you.
