The 1999 Acura Integra features a 1.8-liter, double-overhead-cam, four-cylinder engine. You should periodically check the ignition timing of the engine to maximize its performance and fuel efficiency. The 1999 Integra's recommended ignition timing is 16 degrees but you can adjust the timing to wherever you like. The ignition timing determines when the spark will fire in the engine. You shouldn't set the timing too far from 16 degrees because you may damage parts of your engine.

Adjusting the Ignition Timing[edit]

Step 1 -Warming the Engine

  • Put your key in the ignition of the Acura Integra and turn the engine on. Make sure all accessories are turned off, including the radio, air conditioning and heater. Put the transmission in neutral and engage the emergency brake. Bring the engine to an idle speed of 750 revolutions per minute, or RPM, to get the car warmed up.

Step 2 - Checking

  • Place a jumper in the 2-pin connector under the glove box. Open the hood and connect a timing light to the battery and number one spark plug. You can now observe what the base timing is by looking at the timing mark located on the main crank pulley.

Step 3 - Adjusting

  • Loosen the three distributor lock-down bolts with your 12mm wrench. You can now rotate the distributor with your hand and reset the ignition timing.

Step 4 - Finish

  • Tighten the distributor lockdown bolts with your wrench after you've set the ignition timing. Remove the jumper. Detach the timing light cables and close the hood.
