From the clicking and knocking, that sounds like low coolant level. It happened to me on my ES330. The block heater popped out due to a bad new replacement, they used the old bracket on a new heater. All your codes are misfires. Go to another mechanic. The popped plug can be fixed cheaply with a Helicoil Insert. Then check or replace all the spark plugs. Then reset the codes. Your reduced speed is 'Limp Mode'. From everything you say, I believe you have a coolant leak or coolant issues, which can cause misfires. I just remembered my ES had to have a new radiator about 6 years ago as it was leaking badly. https://www.google.com/search?q=helicoil+spark+plug+thread+repair+insert https://www.google.com/search?q=Lexus+codes+P0300+P0306+and+P0303 I have the FIXD Sensor and App and do my own code stuff. It is basic but does the job. P0300 Causes Multiple misfires can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure. The most common reason for this to happen is faulty or worn-out spark plug coil packs, especially if it's been a while since you had a tune-up.Mar 14, 2018

That red wire is not intended as a power source, you have shorted the unit to ground. Most likely the wire you connected to the lighter is a power out of the head unit not an power in. Check that with a meter or test light. The radio wiring colors for your car are below. 2000 Lexus GS300 Car Stereo Radio Wiring Diagram Radio Constant Keep Alive memory 12V+ Wire: Blue/Yellow Radio Switched from igntion 12V+ Wire: Brown Radio Ground Wire: Gray Radio Illumination Wire: Green Radio Power Antenna Trigger Wire: Black/Red Radio Amplifier Turn On Trigger Wire: White/Blue Left Front Speaker Wire (+): Pink Left Front Speaker Wire (-): Purple Right Front Speaker Wire (+): Light Green Right Front Speaker Wire (-): Blue Left Rear Speaker Wire (+): Black Left Rear Speaker Wire (-): Yellow Right Rear Speaker Wire (+): Red Right Rear Speaker Wire (-): White

Check fuse and check for power and ground at the blower motor itself. If you have power and ground, it sounds like a bad blower motor. If no power or ground, it could be a bad fuse or blower motor resistor.

You may have a burned out fan, jumper 12 volts to the fan and see if it runs, if not replace it and the control relay.

CHECK WITH YOUR LEXUS DEALER COULD BE SAFTEY RELATED

It is your Throttle Position Sensor (TPS), the black component on the side of your Throttle Body normally on the right side as you look from the front of your engine.

Take the **** of a screw driver and tap the TPS, while the car is on, you might notice a fluctuation. tapping again may not yield a response but it is prone to jolts.

Before replacing it, try to check the resistance with a Digital Volt Meter on the terminals. You can check Haynes Book at a local supply store that might have it or go to a book store that carry the books. Each series of Lexus/Toyota have there own value. If the values are off, loosen the mounting screws and turn the TPS clock wise until you get the values needed. A slight movement is all that is needed or tolerated so take care not to over adjust or the fix will not work.

If you want to just replace it then not where it is positioned and place the new one starting at a counter clock wise postion then place the new TPS and rotate to exact position the old one was and then tighten down. Caution it is best to check the resistance values to insure proper adjustment.

Hope this helps

Hi , you need to have the battery checked for condition, it may not be retaining charge because one or more of the cells is in bad condition. Assuming you have a 12v battery, it should be producing rather more than that while the engine is running and the charging circuit is performaing it's task of keeping it charged. Ideally this value will be around the 14 v mark. If the value is below the 12v the battery requires then the battery will not charge but slowly become depleted. Somebody should check the battery output with the engine running , with a multimeter, to establish whether this is the case. If the output is below 12v have the alternator checked, check the drive belt is appropriately tensioned so that the alternator can be properly driven. It may be that the alternator itself is faultyand needs servicing or replacement. It might be that there is a fault with one of the components in the electrical system that is the battery to drain, this is not very unusual and can sometimes be traced to components such as the BCM, (body control module,) an electrician can establish this for you. It should be a fairly straightforward task to track the cause of this problem in the case the battery/belt/alternator are at fault.

You'll need to crawl up underneath the vehicle and trace it back. Most likely, you are leaking oil from the timing cover.

Most likely the linkage isn't set properly on the transmission or worn out

Check temperature should be 39F-41F mean good.

You need to get a set of AC gauges and check to see the pressures in the AC system
