So during the first few minutes, the O2 sensors are non-functional? I just want to make sure the engine is going into CL. Just trying to figure out what would be making it surge, eating gas, and backfiring at random intervals. Even when it's not doing most of this, it seems I have lost power. I'm running out of ideas on this.
As for the CE light, these cars are notorious for not setting a CE light even when there are problems. For example, it WILL set a CE light if I unplug the TPS sensor, but all those KOER codes I constantly get, it NEVER sets the light off. I know it's not those "newer" cars with the OBDII and CAN PCM's ,but it seems the newer the computer type, the more the CE light will go off for even the littlest things. EEC IV however, it takes unplugging a sensor to trigger that.
