         ENGINE MECHANICAL

         Before performing any on-vehicle adjustments to fuel or

ignition system, ensure engine mechanical condition is okay (i.e.,

engine compression).

         VALVE CLEARANCE

         VALVE ADJUSTMENT

NOTE:    All models use hydraulic valve lifters. Adjustment is not

         required.

         CHECKING HYDRAULIC VALVE LIFTERS

         1) Warm engine to normal operating temperature. Remove valve

cover. Position cylinder No. 1 at TDC on compression stroke. On 4-

cylinder engines, check intake rockers on cylinders No. 1 and 2. Check

exhaust rockers on cylinders No. 1 and 3. On V6 engines, check intake

rockers on cylinders No. 1, 5 and 6. Check exhaust rockers on

cylinders No. 1, 2 and 3.

         2) Push downward on end of rocker arm, above lash adjuster.

Rotate crankshaft 360 degrees. On 4-cylinder engines, check intake

rockers on cylinders No. 3 and 4. Check exhaust rockers on cylinders

No. 2 and 4. On V6 engines, check intake rockers on cylinders No. 2, 3

and 4. Check exhaust rockers on cylinders No. 4, 5 and 6. If lash

adjuster is normal, it will feel solid.

         3) If lash adjuster moves downward easily when pushed,

replace adjuster. If lash adjuster feels soft or spongy, air has

probably entered lash adjuster. If this occurs, check engine oil

level. If engine oil level is okay, check oil screen and oil screen

gasket for damage.

         4) After repairing cause of air ingestion, warm engine to

operating temperature. Drive vehicle at low speed for approximately 5

minutes. Turn engine off for a few minutes.

         5) Restart engine and drive at low speed for approximately 5

minutes. Repeat this step several times for about one hour. This helps

remove air from engine oil.

         IGNITION TIMING

NOTE:    Perform all checks with engine at normal operating

         temperature, cooling fan and accessories off, transmission

         in Park or Neutral, and front wheels in straight-ahead

         position. Ignition timing check procedure for Eclipse 2.0L

         non-turbo not available from manufacturer at time of

         publication.

         Diamante

         1) Ignition timing is controlled by Powertrain Control Module

(PCM) and is not adjustable. Manufacturer provides procedure for

checking timing. DO NOT attempt to adjust ignition timing by rotating

distributor.

         2) Start engine and warm engine until engine temperature

coolant is 176-203 F (80-95 C). Turn engine off. Insert a paper clip

in engine speed detection connector terminal No. 3. See  Fig. 1.

Connect a primary voltage detection-type tachometer to paper clip.

         3) Install a timing light. Start engine and allow it to idle.

Ensure engine curb idle speed is about 700 RPM. Curb idle speed is

automatically controlled by Idle Air Control (IAC) system. If curb

idle speed is not as specified, see DTC P0505 in G - TESTS W/CODES

article.

CAUTION: MFI system actuator test must be cancelled or test will

         continue to run for 27 minutes. Driving vehicle under this

         condition may damage engine.

         4) Turn engine off. Connect scan tool to Data Link Connector

(DLC). DLC is located below left side of dash, near steering column.

See Fig. 2. Start engine and allow it to idle. Using scan tool, select

MFI SYSTEM ACTUATOR TEST, then select item 17 (BASIC IGNITION TIMING).

Press "Y" and read basic ignition timing value. See

IGNITION TIMING SPECIFICATIONS table. If basic ignition timing is

within specification, go to next step. If basic ignition timing is not

within specification, cancel MFI system actuator test. See DTC P0335

in G - TESTS W/CODES article.

         5) Read actual ignition timing value. If actual ignition

timing is not within specification, cancel MFI system actuator test.

See DTC P0335 in G - TESTS W/CODES article.
