You need a Catalytic converter and possibly a Evap. cannister

If you haven't replaced the O2 sensor that is causing your check engine light to come on by generating a fault code in the ECM, replace it first. Cleaning the Catalytic Converter is not the thing to do. Replacing the faulty sensor will pay for itself in the long run with the better fuel economy you will get.

The vehicle has probably been stationary for over a year if there are flat spots. But flat spots do not make the vehicle completely unsafe to drive. So long as the tires are not flat you may drive it slowly; keep it under 60 km/h (40 mph) and buy some new tires. Once you hit that speed the vibration will remind you to keep it slow.

Failed Variable Cam Actuators Some of that comes from normal wear Most comes from not changing the oil often or not using 5W-20 Full Syn Oil You can then have blocked oil passages or cam bearing wear, as well, or all the above If you bought a used vehicle,your guaranteed to have someone else's neglect

worn camshaft bearings or leaking cam followers

check door pins and bushings

Open the car hood. There is a black box with a snap-on cover to the right of your battery. Once you remove the top cover, look inside the top and it wiil show you which relay is your A/C relay. I believe it is a white colored relay located back right in the relay block or holder.

If you are talking about the AC, then I suggest cleaning or replacing the cabin air filter located behind the glove box. See your owners manual for details. If problem persists replace the AC clutch relay ( rockauto.com $11), located in the under hood fuse box towards the front of the fuse box.

Toyota has a tech service bulletin on this issue But this is how the system works the car electrical system applies 12 volts to solenoid and the computer supplies the ground to operate the shift solenoid. once the command has been sent and the computer see no change in the input speed verses output speed it sets the po770 several things can cause this problem from bad torque converter to sticky valve body control valves and wiring issues. This can be diagnosed with a enhanced scanner without taking anything apart.

Get a new starter

according to my receipt from my last oil change, it is 3.6 quarts.

Yes, the car can be driven but it is advised to check in a timely fashion the reason for the MIL to have come on.

The same 15amp fuse for the regular brake lights powers the high mount light. If the regular brake lights work but the high mount does not, it could be the lamp monitor or a wiring problem.

There are two fuse boxes, one is under the hood near the battery and the other one is inside at the left of the dash just behind the edge of the dash, you'll have to look up with a light to see it, should have a black cover on it about 1 inch wide and 5 inches in length/

Any imperfections or flat spots will be worked out after you drive a few miles to get some heat into them. Some tires even develop flat spots overnight. It's normal for pretty much all tires...Keep driving on them, may take 500 miles of easy driving...It may make you nuts listening to the noise until they round out after some driving...saailer I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

Why do think its a relay?? if it is a single click or sometimes no click noise when turning the key it is the starter itself. If it is a repetitive click it could only be the battery. If you hear a click, this is the relay you are asking about, however it is extremely rare for a Toyota. Please have someone help you with the next step. Get a long metal rod or long pry bar about 2' long and a hammer. Locate the starter, it will be on the driver side of a left hand drive vehicle between the engine and the transmission. Set one end of the rod on the body of the starter and tap the other end firmly with the hammer. You don't have to kill it. At the same time as you do this, your helper will be in the car holding the key in the fully start position, don't touch the gas as it may flood the motor. in mant cases this may start the car. If you live in a cold climate where they use salt on the roads, there is a small chance there could be a bad ground to the starter but only a 2% chance of this. of you are handy and can remove the starter yourself, you should check the starter contacts inside the starter. these copper contacts are usually the only thing that wear on a Toyota reduction type starter. And are not vert difficult to replace if you are comfortable with this level of technical expertise. Or you can order a new starter from your Toyota dealer as you already know the last one was good for 11 years and they usually have a less expensive rebuilt starter available for your corolla. 28100 STARTER ASSY Replaced by: 28100-0D080-84 28100-0D080 2003.05-2004.05 1ZZFE..
