help me with these codes...

freelander 2004 HSE ,,fault code
P0304
P0306
P0303
P0300
P0150
P1472
P0174
i replaced all coils and plugs and vis motors and still misfire ,don't know what to do.can you help me ?

Multiple cylinder misfiring access both banks of cylinders would suggest a fueling issue. With those codes, I'd be checking the fuel pressure before delving any deeper.
VIS motors can be ignored when tracing misfiring faults.

ok thanks

about o2 sensors?

Please ?

I'm not an expert on this stuff, but looking at your codes and comparing to the ones in this link it looks like an O2 sensor problem for bank B.

P0303 throws a spanner in the works for a single O2 sensor fault, other than there being no O2 sensor fault codes.

I'd be checking the fuel pressure is circa 60 psi before delving deeper.

True about P0303 which suggests both O2 sensor faults, but the other codes don't back this up (I hadn't twigged to this) - as I said, I'm no expert

thank you ,also i had to hold the gas pedal to the floor to keep the car running if i release it Car shuts off

Wots a gas pedal?

Pedal car toy throttle maybe ?

Maybe its a pedal that makes you fart when you push it.
