1998 Acura Integra Questions & Answers
1998 Acura Integra. P0301 misfire.
If you have already checked the spark plugs, plug wires, fuel injectors, and distributor and are still experiencing a misfire in cylinder 1 and 2, here are a few more things you can check:
- Compression: Check the compression in cylinder 1 and 2 using a compression tester. Low compression could cause a misfire in one or both cylinders.
- Vacuum Leak: Check for a vacuum leak by inspecting all hoses and fittings for cracks, damage, or looseness. You can also use a smoke machine or propane torch to locate any leaks.
- Ignition Coil: Check the ignition coil to ensure it is functioning properly. You can do this by swapping the coils from cylinder 1 and 2 with the coils from another cylinder and see if the misfire follows the swapped coil.
- Fuel Pressure: Check the fuel pressure to ensure it is within the manufacturer's specifications. Low fuel pressure can cause misfires.
- EGR Valve: Check the EGR valve to ensure it is functioning properly. A malfunctioning EGR valve can cause misfires.
- PCM/ECU: If all other components have been checked and are functioning properly, it is possible that the PCM/ECU (Powertrain Control Module/Engine Control Unit) may be faulty and may need to be replaced.
It is recommended to perform these checks in a methodical manner to narrow down the cause of the misfire. If you are not comfortable performing these checks yourself, it is recommended that you seek the assistance of a professional technician.

might be a timing issue. check if your spark plug wires are seated correctly also you might have a dirty fuel injectors. a good cleaning might help as long as they are not leaking.
Trouble shoot
I believe that's a Speed Sensor issue.
Diag:
1. Ensure mainshaft and countershaft speed sensors are installed properly. Disconnect mainshaft speed sensor harness connector. Using a DVOM, measure resistance between sensor terminals.
2. If resistance is not 400-600 ohms, replace mainshaft speed sensor. If resistance is 400-600 ohms, disconnect 25-pin PCM harness connector "B". Check for continuity between ground and 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).
3. If continuity is present, repair short to ground in Red or White wire between PCM and mainshaft speed sensor. If continuity is not present, reconnect mainshaft speed sensor harness connector. Measure resistance between 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).
4. If resistance is not 400-600 ohms, go to next step. If resistance is 400-600 ohms, go to DTC
P0720 (FLASH CODE 9) . Check for loose PCM harness connectors. Replace PCM with a
known-good unit if necessary.
5. Disconnect mainshaft speed sensor harness connector. Check Red wire for continuity between 25-pin PCM harness connector "B", terminal No. 15 and mainshaft speed sensor harness connector. If continuity is present, go to next step. If continuity is not present, repair open in Red wire between 25-pin PCM harness connector and mainshaft speed sensor
harness connector.
6. Check White wire for continuity between 25-pin PCM harness connector "B", terminal No. 14 and mainshaft speed sensor harness connector. If continuity is present, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary. If continuity is not present, repair open in White wire between 25-pin PCM harness connector and mainshaft speed sensor harness connector.

How to Clean a Solenoid Starter in Acura integra car?
1) Keep the starter on a clean surface.
2) Clean the starter with lubricant cleaner.
3) Remove the motor from starter by removing the bolts holding the starter.
4) Clean the bolts also with the lubricant cleaner.
5)After the bolts are removed the stater will come out.
the inner cylinder connected to the starter will not come out.it will remain in place.
6) Properly clean all the components with lubricant cleaner.
7) Use cleaning brush and rag to clean all the inner components.
8) The starter is cleaned now.
8) Then reassemble all the components back.
This will help.Thanks.
