  2. On Q45, disconnect ignition coil harness connector. Using ohmmeter, check resistance between coil terminals No. 1 and 2 (cylinders No. 1 and 2) and terminals No. 2 and 3 (cylinders No. 3 and 8). See Fig 2 . Resistance should be approximately .7 ohm. If resistance is not as specified, replace ignition coil.
