So my 2001 Corolla has a p0300 code. I’ve changed the spark plugs, coils, fuel pump, intake manifold gasket, front o2 sensor, fixed my exhaust leaks, changed the pcv valve and coolant temp sensor and it is still throwing the code. At random and sometimes can go a week or so without happening is you will be driving the car and then all the sudden the car will sputter like it’s either getting to much air or fuel. The only thing I haven’t changed in the fuel injectors. Any help is appreciated.
P0300, cant figure it out.
