I've already posted this issue on Honda-Tech, but I'm not getting any responses, so I thought I'd ask here too.
To give you a rundown on whats happening, my Civic doesn't rev all the way to redline. Instead it breaks up around 6,500 to 7,000 and I'm forced to shift. The sound coming from the exhaust sounds like a small gun too.
The issue started a few months ago. At that time, the car already has new plugs, new leads, and a decat. I've also cleaned the VTEC solenoid and replaced all the gaskets for new OEM ones. Someone said its the solenoid. I cleaned it already. Theres no debris on the mesh, so that rules the solenoid out. Seen some people say my cat is possibly clogged. Thats not possible since the issue appeared with a decat installed.
The component that seems to be the culprit is the distributor. I've already swapped the rotor for a new one, and the coil for a NGK replacement.
You can see how badly corroded the OEM one is.
Little hotspot.
With the new coil in, the car is still 'broken'. I couldn't replace the ignition module, even though I have the correct part. I bought an OBD2 ignition module, as shown in the photo. I even checked if I had an OBD2 distributor, which I do. Checked the wiring harness plug too. The distributor in the car currently has an OBD1 ignition module wedged inside. I watched YouTube tutorials before disassembling the distributor and the module is suppose to slide out easily. I inspected the module and its definitely an OBD1 and pliers can't make it budge.
I still need to order a new cap from Honda, but is there anything else I can try? Am I fixing the correct part or am I wasting my money?
Heres a video of the issue. Listen carefully to the sound of the car.
