Fault code help please

Russ_123

Ok guys, so the following codes and faults have come up...

***P0172-00 - system to rich

P0300-00 - Random/Multiple Cylinder Misfire Detected***

Question is, how do I get these fixed?

Do I just tell my local garage and they will sort it, very confused :wtf:

Hope someone can help...

p0172 points towards front lambda sensor

p0300 is a useless code

Could the front lamba sensor be causing the puff of air I mentioned in my other post then mate?

MikeS

what other post ?

if it is black smoke coming out of exhaust then it is most likely over fueling

might well be front lambda but worth cleaning out throttle body as they give out incorrect throttle positions if severely oiled up and cause ECM to overfuel
