_shaun_ Posted May 5, 2015 Share Posted May 5, 2015 have you spoke to the mapper to see what they think? possible you have accidently knocked your fpr or something and uped the fuel pressure? other than that id think air temp sensor/ water sensor/ lamda/wideband could throw up issues that would cause this Quote Link to post Share on other sites

_shaun_ Posted May 5, 2015 Share Posted May 5, 2015 ha i wasnt commenting on your car.you said you cant base that your running lean based on the smell of fuel and black plugs. you have it the wrong way round rich is to much fuel lean not enough Quote Link to post Share on other sites
satyrs Posted May 5, 2015 Share Posted May 5, 2015 maybe there is a injector faulty. that doesnt close well. get the injectors out on the rail and let someone else turn the car over. see if the spray patern is the same of all 4. Quote Link to post Share on other sites
