The Mass Airflow Sensor is what you left off. That will generate a code and the car would run poorly.

Option 1. Get the code cleared by a mechanic

Option 2. Get a blue tooth obd2 to plug in. Heaps on eBay. Download “Dash command” from google play or from App Store (for apple)

Find the code to be sure that’s your problem. You will be able to clear the code as well.


When you disconnect sensors etc, you really should have the negative terminal disconnected. At the very least, don’t have the radio on while you do it. Switch the car off, but that’s not ideal.

Really bad (but good because no cost) option 3.
Try disconnect the battery overnight or for the day. Switch the lights on, beep the horn or similar for some shitty attempt at bleeding off some residual power once it’s all disconnected. Reconnect. See if things are ok. Won’t cost anything.

The fuel gauge is operated by the BCM (body control module) under the dash by the steering column. This can be a symptom of a faulty BCM.
