Underpowered

tellreded · 05-06-2018, 09:23 PM

So, my car seems very underpowered right now. Ive done some fake Dyno tests with obd apps like dashcommand and force. Force says torque and bhp is very low, but the curves look very normal. On dashcommand, I can only see current and top produced torque and hp and on a stand still pull, the most torque I see is in first gear with 246lb/ft and the highest hp in 5th(I think) at 198hp. I think I'm going to disregard the dask command readout, but it is feeling really underpowered when I drive the car. Currently, I have four lambda probe dtcs (2C9C, 2c9d, 2c9e, 2c9f). Would this be causing the lack of power? Or would it be something else?

Thermostat was recently redone, a/c was recently refilled, and 6 brand new BMW OEM spark plugs were put in.

You have engine codes for the O2 sensors.

Car does not seem to be running right.

Going to go out on a limb, but I bet they are connected.

What mileage are you at?

Might be worth doing coil packs too - some people argue that they're not wear items, I disagree. I had one die on me so I swapped them all out and have been getting smoother everything and improved mileage.

Car is at 138000 km, engine is 41000. Coil packs maybe cause there was an oil leak, so the coil packs got covered in oil. I cleaned them out with a pencil and paper towel on the inside and let the rest of the oil dripping out over night by a heater.
