Fotis Posted January 27, 2019 Author Report Share Posted January 27, 2019 Well ,no way that's lean wideband reads 11.3 AFR @ WOT.. Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted January 27, 2019 Report Share Posted January 27, 2019 Difficult to see the plug looks old but there is a lot going on, the plug is to cold, the timing looks too advanced and the fueling looks ok, you say 11.3:1 but you haven't said what fuel you are using.

Fotis Posted January 28, 2019 Author Report Share Posted January 28, 2019 I am using 98RON (european fuel ). Well the timing in my opinion is low and there is no knock occurring. Quote Link to comment Share on other sites More sharing options...
