Additions:
1. Warm engine to normal operating temperature. Remove valve cover and spark plugs. Rotate [[BottomEndSpecsB18c crankshaft]] to bring piston No. 1 to TDC on compression stroke (lifters on cylinder No. 1 should be loose).
2. Measure [[ValveSpecsB18c valve clearance]] on intake valves for cylinders No. 1 and 2 and valve clearance on exhaust valves for cylinders No. 1 and 3.
3. Rotate crankshaft 360 degrees to bring piston No. 4 to TDC on compression stroke. Measure valve clearance on intake valves for cylinders No. 3 and 4 and valve clearance on exhaust valves for cylinders No. 2 and 4. Adjust [[ValveSpecsB18c valve clearances]] by replacing lifter shims.

2. Increase engine speed to 2000 RPM, 2 or 3 times, then allow engine to return to idle. Ensure ignition timing is set correctly. Check idle speed.
**KA24DE IDLE SPEED AND CO% LEVEL**
2. Locate ECM. Start engine. Raise engine speed to 2000 RPM. With idle speed and ignition timing set correctly, ensure Malfunction Indicator Light (MIL) and Red light on ECM goes on and off more than 5 times during a 10 second period.
7. Start engine and warm to normal operating temperature. Increase engine speed to 2000 RPM, 2 or 3 times. Check idle mixture (CO% level). Remove 2500-ohm resistor from engine coolant temperature sensor wiring harness connector. Reconnect sensor.
