Hello I took my car to an emission test and it fail beacuse of two codes which the first one is p1320: manufacturer controlled ignition system or misfire and p1130: manufacturer controlled fuel and air meeting what can I do to fix this problem. Thanks
1. Turn ignition on. Measure voltage between ground and PCM harness connector terminals No. 1, 2, 3, 7, 8 and 9 by backprobing. See Fig. 2. Voltage should be .01 .10 volts. If voltage is as specified, go to next
step. If voltage is not as specified, repair open or short circuit. See appropriate diagram in WIRING DIAGRAMS article.
2. Turn ignition off. Disconnect condenser and each ignition coil harness connector. See Fig. 37 and Fig. 38 . Turn ignition on. Measure voltage between each ignition coil harness connector terminal No. 1 (Red
wire) and ground. Also, measure voltage between condenser harness connector No. 1 (Red wire) and ground. If battery voltage exists, go to step 4. If battery voltage does not exist, go to next step.
3. Turn ignition off. Check for open or short circuit to ignition coils or condenser. See appropriate diagram in WIRING DIAGRAMS article. Repair as necessary. If circuits are okay, disconnect condenser and
measure resistance between condenser terminals. Resistance should be more than one megohm at 77 F (25 C). Replace condenser if resistance is not as specified. If resistance is as specified, go to next step.
4. Check continuity of Black wire between each ignition coil harness connector and ground. If continuity exists, go to next step. If continuity does not exist, repair open in appropriate Black wire.
That is for code 1320 it cold be a bad coil as well. Code p1130 ccan either be the swirl control valve solenoid or the clip may be loose on it. Pic enclosed. Its 'a dealer item.
