Video shows the car starting and stalling.
Started with a code P0300 first for a few months.

replaces my spark plugs, coil packs, cleaned throttle bodys and MAF. But none of this fixed the issues. I was still misfiring from time to time. Loss of power, terrible fuel economy.

Replaced fuel injectors. Turns out they were aftermarket garbage. Back to oem and the P0300 code still persisted.

Fast forward just a few days ago. I refuelled and my car started shifting super aggressively. My VDC light and traction control light both came on too. My break fluid and brake pads are just fine by the way.

My car started limping that day and also stalling. limped all the way back home. I ended up with the same code P0300, Misfire on cylinder 3, and P010C. I replaced my spark plugs once again, cleaned throttle body, cleaned MAF sensors, and I also replaced my valve cover gasket since it was leaking.

Lots of labour for a whole lot of nothing cause now the car is giving me the same bull**** with code P0100 and as always, code P0300. It struggles to start, then it just stalls. Anyone here know what the hell is going on here?




What light my car had as soon as it started shifting weird and when finaly staling/limping.

 

Did you check the camshaft and crankshaft sensors? Replace with oem?

Battery is good?

throttle body positioning is good?

no exhaust leaks?

 

So my next step would be the bank 1 sensors. The battery I know is good to go. I know my cats are toasted too. How would an exhaust leak cause such an issue? Thanks for your reply!
