92 h22a prelude misfire plz help...
Hi guys I have a big problem plz help...
I have a 92 h22a prelude and it's running rich and tends to misfire .. I checked the compression it's fine I change the TPS sensor with the map sensor and also the TB still misfiring. I have a hard time starting it in the morning. It idles hard before it warms up. The spark plugs are pitch black. My car is running on the stock h23 harness and I'm running p28 ecu I hit vtec that works the harness is a OBD0 and the engine is OBD1 maybe that may be the problem but not sure the check engine light is in its give off code 41 O2 sensor if someone can plz help me thanks!

Re: 92 h22a prelude misfire plz help...
iv came to a conclusion I've been using NGK Iridium sparks and they don't burn the gas as fast as the NGK R spark plugs I have my car in the shop right now working on clutch, header new NGK O2 sensor and I'm trying the new plugs. I'll see how it will run I'll let you know thanks!!
