Engine Tune up include three areas to be addressed in order to get most out of car and to comply with the recommended standards.
1. Fuel system.
- Inspect element air cleaner. Apparently if it seem to be in good condition, clean it with dry compressed air blowing from inside out. Replace it if found clogged. Always clean the element air cleaner immediately after driving through rainy or dusty area.
- Do the throttle body cleaning and and idle speed re-learning. Idle speed re-learning procedure is as under:
-- Make sure coolant level and engine oil level are up to the marks.
-- Remove the key or remote from the car. Remove the battery negative terminal for 5 Sec or more and re-connect.
-- Sit on a driver's seat. Close all the doors, gear in N or P, hand brake pulled. Switch off all the accessories like radio, DVD player, room light, blower motor, parking lights etc.
-- Start the engine and hold the throttle at 3000 rpm till the radiator fan becomes on. After the fan becomes on, release the throttle and let the engine at idle for eight minutes.
-- Switch off the engine and wait 5 Sec. Start the engine and the idle speed learning is complete.
-- Now learn the body ecm. Switch on the ignition lower the driver's window, hold it for 3 Sec then release the button. Lift up the window, keep the button pressed for 3 Sec, after the window reaches top, and release.
-- Do the same procedure with all the remaining windows while sitting in front of the individual windows.
2. Ignition system:
- Remove all the spark plugs and visually inspect them for deterioration of the electrodes. any cracks on porcelain, and color to get an idea for the engine condition. If the color of the electrodes are brown, clean and dry, the engine and performance is excellent. If black and dry, it shows excessive fuel consumption due to the low pressure of fuel pump, clogged element air cleaner, intake blockade, throttle body clogged, faulty MAF sensor, faulty heated Oxygen sensor and defective or leaking fuel injectors. If white color, the system is lean or the fuel is water contaminated. If oily and black, it reveals the oil is getting into the engine through some external source or engine failure.
- Adjust the spark plug electrode gap to 1.00 - 1.1 mm.
- Inspect the ignitors and connectors for firm and good appearance.
3. Engine compression system:
Check the compression of each cylinder with the help of cylinder compression gauge. If the cylinder compression is found less than the specified, it could by due to valve clearance too low or the engine valves and guides are gone bad. Or it may be due to the worn out piston and rings.
Valve clearance (cold):
for intake:
0.15 to 0.25 mm (0.006 to 0.010 in.)
for exhaust:
0.25 to 0.35 mm (0.010 to 0.014 in.)

What does a tune up consist of on a 2008 toyota yaris?

It depends on the mileage, in most cases it's just a replacement of spark plugs and an air filter, there is really no such thing as a "tune up" anymore since all engine functions and adjustments are made by the computer.

ABS and Check Engine Lights on

This could be the case, Car computers don't like being started other than how it was suppose to be started, You will need an error code reader just to confirm there are no problems with the engine then you can clear any stored error codes which will turn off any lights you have on.

Crashed my 2006 yaris

It's most likely engine coolant. Get a white rag or paper towel, and put in the fluid. Is it green? If it is, it's engine coolant. The cooling system (radiator) is located in the front of the vehicle, so it's the 1st thing to be damaged in an accident. If the fluid isn't green, post more info (color) and I'll try to help you.

Automatic engine immobilizer wo'nt reset

The immobilizer does not "lock" the ignition, it does not energize the fuel injection relay. What you have is a "locked" steering column. Put the key in the ignition, and pull/turn the steering wheel HARD left or right, whilst turning the key to on or start. Do BOTH at the same time.The action of you pulling on the steering wheel will unlock the steering column.
