 | 1. With the ignition off, in accordance with the manufacturer's instructions, connect the stroboscope. On models 1993 and 1994 Vol. induction receiver is connected to the strobe explosive spark plug of the first cylinder. models from 1995 MY. in the corresponding wiring harness of the ignition coil, a special loop to connect inductive sensor strobe.  | If the design does not allow the strobe to connect it to loop wiring explosives, remove the coil of the first spark plug. Restore initial connection of electrical wiring, connect the spark plug wire between the coil and the spark plug and connect it to the strobe. |

2. Cock a lay brake, prop up the rear wheels of a vehicle wheel chock and set the transmission to "P" or "N".
3. Locate the timing marks on the crankshaft pulley (a pointer mounted on the cover of the timing). TDC on the pulley highlighted in yellow paint. On models 1993 and 1994 Vol. Step location labels on a pulley of 5 ?�, TDC is at the left. Look for a label 15 ?� before TDC. If necessary, clean the pulley to improve visibility.  |  |
4. Start the engine and warm it up to normal operating temperature (the upper radiator hose should become hot to the touch). Verify proper installation of the engine idle speed (see chap. Engine management). Raise the engine speed to the value 2000 in a minute, and then again to reset them to idle.
5. Direct a stroboscope beam on the crankshaft pulley and check the ignition timing (corresponding to the label will still be located next to the pointer).
6. On models 1993 and 1994 Vol. if necessary, loosen the clamping bolt of the distributor and rotating the body of the latter, make an appropriate adjustment to the ignition timing. Tighten the bolt and retest.
7. On models since 1995 Vol. in the event of ignition timing Check the functioning of the crankshaft position sensor and camshaft (see chap. Engine management). If the sensors in the order, drive to a repair shop for diagnostics and regenerative repair of PCM.
8. Stop the engine and disconnect a stroboscope. |
