What causes a po300 code

Question

Suzuki Reno 2006 is coming up PO300 what is this code and what do I need to do

Answer 1

Hi there,

There can be several causes for this code. Basically the engine has multiple misfires. This could be due to low fuel pressure, the need for new plugs or coils, issues with the timing belt and the mass air flow sensor. All of these can cause problems with the fuel mixture and cause multiple misfires.
