1990 Chrysler Le Baron timing

IGNITION TIMING (4-CYL & 3.0L) 1. Place gear selector in Neutral. Turn off all lights and accessories. If magnetic probe timing light is being used, refer to equipment manufacturer's instructions for service procedure. If conventional timing light is used, connect timing light to No. 1 cylinder. 2. Start engine and warm to normal temperature. Connect tachometer to engine and ensure idle RPM is to specification. Disconnect engine coolant sensor lead wire. CHECK ENGINE light should illuminate. 3. Check timing through timing window in bellhousing on 4-cylinder models or on crankshaft pulley for 3.0L. If timing is within 2 degrees of specification, do not adjust. If timing is incorrect, loosen distributor hold-down bolt and turn housing until specified timing is obtained. 4. Recheck timing after distributor hold-down bolt has been tightened. Reconnect coolant lead wire. Erase any fault codes. Recheck curb idle and adjust (if necessary). Remove diagnostic equipment. IGNITION TIMING (3.3L) CAUTION: Timing light secondary connection should be made with inductive pick-up. DO NOT puncture cables, boots or nipples with test probes. NOTE: Basic timing is fixed and has no means of adjustment.
