Anyone know what's causing this problem? I'm waiting on a few parts (an ignition coil, 4 spark plugs and an air filter) but I'm not sure if those will solve it for sure. It wasn't anywhere near this bad before...At first I only noticed the car shaking like it was about to stall when I slowed down to around 5kmph to 10kmph but anything above that speed was fine. I stopped using the car for about 2 weeks while I was waiting on some parts to be shipped here (I'm in the Caribbean). I started the car again today and this is what's happening now.. it got a lot worse! Any ideas on how to begin solving this?
The CEL code is P0031 (Oxygen Sensor Heater Control Circuit Low (Bank 1 Sensor 1)) but this code popped up ever since I replaced my stock intake with a K&N typhoon.
What do you guys think is the problem here, given the symptoms shown in the video? The last part of the video is showing that the car isnt revving past ~2000rpm even though I'm almost flooring the gas.
