If Biggy1 has described it right, I think when you remove the WIRE to the spark plug ( not the plug itself ) and oil jumps out, there is a cylindrical seal that needs replacing and one does not need to even remove the cylinder head.
I have the same problem with my corolla. On the other hand if Biggy meant when removing the SPARK PLUG oil was on the contacts....

the plastic frame around it should snap out with a flat head screwdriver to get access.

SOURCE: Sensor Wire/Fan 1990 Toyota Corolla

These wires could go to a temperature sensor for the radiator fan. The best thing to do is to bypass the sensor and straight wire the fan to come on when the engine is running. I had one to over heat because the sensor went bad and wouldn't let the fan come on.

When the fuel trim is high teens or in the 20s then its the MAF that the problem. If fuel trim is normal, 2-5 then its the O2 sensor.

MAF-
Buy "Electrickleen" at the parts store.
Remove the MAF sensor, WHILE COLD, and blast the wire inside with cleaner.
The "hotwire" gets gummed up and changes the resistance of the wire so you get a bad input to the ecu and it trys to lean out for a rich condition that doesnt exsist.When it cant adjust anymore it trips the po171 code.

To have so many different codes at the same time indicates that the first place to start looking is the wiring harness itself. Locate the MAP (manifold air pressure sensor - code 31) and IAT (inlet air temperature sensor - code 24) connections. Disconnect and reconnect each sensor a few times and check that the connecting socket and pins are clean and free of corrosion - the codes indicate intermittent breaks. Check all fuses are clean and well mounted. Examine wiring harness for chafing, abrasion and signs of wear. Any intervening connections between the wiring harness and electronic control unit (ECU) need to be checked over and should be free of oily grime.

Location air temp sensor


Location of Intake Air Temperature Sensor:
The intake air temperature sensor, which is mounted on the mass air flow meter, monitors the intake air temperature. The intake air temperature sensor has a built-in thermistor with a resistance that varies according to the temperature of the intake air. When the intake air temperature becomes low, the resistance of the thermistor increases When the temperature becomes high, the resistance drops .

Either the mass-air sensor is bad, which normally throws a mass-air voltage code, or you definitely have an air leak post the mass-air. Smoke the intake manifold with a smoke machine or spray the whole intake to head, including to brake booster with brake cleaner and listen for a change in idle. Focus on the gasket surface of the intake manifold.

My engine light is on, and its code P0171 (System too lean Bank 1). Its toyota corolla VE 200. How do i fix it ? I am looking for mass air flow in my car ? I dont know where it is located ?


Remove the two screws that hold the MAF on the intake near the air filter, go to an auto parts store or electronic supply place and get a can of spray electronic cleaner, spray the inside of the air flow sensor, you need to get it into the small opening where the platinum sensor wires are, they get coated with dust and other gunk and confuse the computer because it gets the wrong signals,clean the wires until the look shiny, reinstall it, you may be able to clear the check engine light by disconnecting the battery and waiting 10 seconds, also replace the air filter and you should be good to go. ------- Check fig:-- bcc2a69.gif
Mass air flow sensor. Located in the intake near the airbox. 2 screws hold it in. Thanks.

Toyota Corolla GL 90 model


Look for a valve in the hose connected from the brake master's hydrovac going to your engine's intake manifold . check if it is still working, the valve traps the vacuum from your manifold to the hydrovac. Replace valve if air passes it on both sides.
