I’ve been having code 43 for a year now and I’ve changed the PCV valve, MFR, fuel regulator, fuel filter, O2 sensor, fuel pump and today I just changed the fuel injectors. And that pesky code 43 is still popping up
I changed the spark plugs and wires with the rotors about a year and a half ago. I just checked the distributor visually and I didn’t see any metal shavings or oil inside.
About a week ago the car started losing power, feels like the fuel is getting cut off especially up hill, the tachometer was bouncing erratically as well… that’s why I finally changed the injectors. After installing the new RC injectors the car wasn’t losing power but something else happened. While I was cruising, about 60 mph, then suddenly the car shut down as if someone turned the ignition off. Luckily I was able to steer and stop the car on the shoulder since every pressure on the car just dropped. I started the car again and it started with no problem.
I’ve searched and searched on this forum but I didn’t find anything that can help me. I’m just wondering if you guys could help me out. What else did I miss, the only thing I could think of now is the ECU or maybe something electrical. I would really appreciate any suggestion. Thanks!
My car is 91 integra, LS with a stock B18A1.
