Is your engine a 3.2L? If it is do you have a fax number to fax the instructions over to you? Kind of hard to post instructions and images for step by step instructions.

No I do not, just a gmail Padillaray08@gmail. Com. I just put a timing and new water pump in because my car was over heating and I took the thermostat out and put a new radiator and my car still gets hot. The fans come on and everything. I do not know what it is.

Sure here you go,

Turn ignition off. Remove ACG fuse (No. 15, 7.5-amp) from under dash fuse box for 10 seconds to reset ECM. Check ECM for fault codes. If Code 18 is not present, problem is intermittent. Check for poor connections at ECM connector and ignition timing adjuster connector. Test drive vehicle and retest.
If Code 18 is present, turn ignition off. Disconnect ignition timing adjuster 3-pin connector from control box. See Fig 1. Measure resistance between terminals "A" and "C" of ignition timing adjuster.

Resistance should be 3500-6500 ohms. If resistance is as specified, go to step 4. If resistance is not 3500-6500 ohms, replace ignition timing adjuster.
Measure and record resistance between terminals "A" and "B" on timing adjuster side of harness connector. Measure and record resistance between terminals "B" and "C" on same side of connector. Add both resistance values together.
If total resistance value is not 3500-6500 ohms, replace ignition timing adjuster. If resistance is 3500-6500 ohms, turn ignition on. Measure voltage between Yellow/White (+) and Green/White (-) wire terminals on wiring harness side of connector. If voltage is about 5 volts, go to step 8.
If voltage is not about 5 volts, measure voltage between ground and Yellow/White wire terminal. If voltage is about 5 volts, repair open in Green/White wire between ECM terminal D22 and ignition timing adjuster connector.
If voltage is not about 5 volts, turn ignition off. Connect ECM Test Harness (07LAJ-PT3010A ) between ECM and ECM connectors. See Figure. Turn ignition on. Measure voltage between test terminals D20 (+) and D22 (-). If about 5 volts are present, repair open in Yellow/White wire between ECM terminal D20 and ignition timing adjuster. If voltage is not about 5 volts, replace ECM and retest.
If voltage between Yellow/White and Green/White wire terminals in step 5 was about 5 volts, turn ignition off. Reconnect ignition timing adjuster connector. Connect ECM Test Harness (07LAJ-PT3010A ) between ECM and ECM connectors. See Figure.
Turn ignition on. Measure voltage between ECM terminals D8 (+) and D22 (-). If voltage is not 0.5-4.5 volts, repair open or short in Blue/Yellow wire between ECM connector terminal D8 and ignition timing adjuster. If voltage is 0.5-4.5 volts, replace ECM and retest.
IDLE SPEED & IGNITION TIMING

Ensure idle speed and ignition timing are set to specification. See IDLE SPEED SPECIFICATIONS and IGNITION TIMING tables. For adjustment procedures, see ADJUSTMENTS article in this section.
