I have a 2001 Toyota Corolla with a 4ZZ-FE engine (1.4 ltr, VVT). I am wondering if you can tell me which marks on the crank and cam gears I line the yellow marks of the timing chain with. Thanks.
Please buy a cheap shop manual. Get this wrong and you will be very sorry.
Thanx...my husband is repairing this car.....will tell him

Idle is factory set and cannot be adjusted, your best bet is checking for cracked hose pipework for air intake at idle,(not at problem under exceleration and driving) Any slight upset to the air /fuel ratio will be most prevelent at idle speeds.Check hoses where the meet metal flanges on manifold intakes and any sharp bends in ppipes.Good luck

Check your idle speed control valve situated at the bottom of the throttle body. Sometimes the valve sticks and will make the engine rev high or low at idle and the ECU can't adjust it properly.
