The old Corolla central control fuse is in the cab fuse box, my harga vios is also in this way.

Check coolant temp sensor that send signal to the ECU. Common failed part that acts like choke on older cars.

Listen, if your fluid is nice and pink and the car is running fine, leave it alone and don't change the fluid. Doing so very often affects the seals due to the presence of a new fluid and leads to leaks, slippage, transmission job! You have been warned. Good luck

if the battery was removed wrong it could have damaged the ecu. the ecu does not like the positive lead removing first. even without the ignition being on a little power still goes into the ecu. you might be able to repair the ecu some ecu's in the old type ecus had a fuse on the ecu board it could of just blown this.

is it fuel injected or an older technology car ie carburetor type fuel ? once I had an older car that had a seal leak in carb and would do this as the fuel would evaporate over night ! had to change the carby over with a reco one.

seems like you need an alternator try charging your battery star the engine and take off negative cable if engine dies it's your alternator. did you have an alternator light on in the dash

the spec is .043", for both the V6, and the Inline 4. The theory behind enlarging gaps, is that a larger gap creates a larger spark, thus more effecient ignition. The problem is, your ignition system was designed for the .043" spark plug gap, not larger. Enlarging the gap puts a greater strain on your ignition system components, and it may not be strong enough to jump a larger gap. The result would be less efficient combustion, or a cylinder(s) that won't fire at all. Pull your plugs, and set them at .043". Check the distributor cap, rotor, wires, and your filters. Make sure the car is totally warmed up before the smog test. Good luck.

91 is ok to run as long as it's not ethanol!! 95 is better but more expensive...

Most likely the calipers need to be replace.

yes it could be the carb and can also be distributor timing or its sucking air in one of the breather pipes or the manifold gaskets isn't as good anymore again resulting in air suction so first check the pipes then spray some carb cleaner in the carb and hold the rpm at about 2500 or try revving it up to 4500 gradually and choke it on top of the carb with your cause it might be dirt stuck in carb

it is the alternator or the regulator. get parts store to swap out under warranty.

If you remove the switch in the effected door, you can pull the wires to that switch and then run a 12 volt source power supply(i've used a battery from a cordless drill. It doesnt take much juice) directly to the wires, making certain that you swap the wires from pos. to neg. trying it in both directions, This will ensure you've got a good wire harness from the main over to the remote window. If the window moves, it's the switch. If it stays up, then you have a bad wire.>hope this helps

it is normally mounted around the brake pedal area

check your fuel system and spark try throwing a little gas in the carburetor and see if it will start if not check for spark take out a plug and ground it turn over the engine there should be spark if it starts after throwing gas in the Carburetor its a problem with your fuel pump

So if you are getting spark to the plugs, are you getting normal fuel pressure and injector pulse ?

are you allowing the car to warm up first before checking your adjustment screws? have you also checked the timing of your vehicle?

Freeze plugs are round steel plugs on center of the engine block. design to come out if the coolant freezes. after a wile the steel build rust and leak. Some of the plugs are below the exhaust manifold and other on the back below the intake. If you see rusty plugs replace all. good luck

there will be 2 locations. under the dash and under the hood
