Explorer high flow cats / OBD II Codes
Two questions:
1. Does anyone manufacture a high flow cat system for a '96 Explorer 5.0?
2. I'm getting a code of P0141 (O2 Sensor Circuit Malfunction-Bank 1 Sensor 2. Which sensor is this and is their a way to check the sensor with a volt meter (i.e. 12V out) or some other means? Also getting the P0402 (Excessive Exhaust Gas Recirculation Flow) I have had this one for over a year now and it causes the Check engine light to stay on. I had the dealer check this one they replaced the EGR and recalibrated the computer (at my expense of course). Niether fixed the problem.
Is this cat related O2 sensor related or exhaust related or a combination of the three?
Explorer has 90K miles on it with original exhaust.
TIA
