guys i keep failing the emissions test. im good on everything but my NOx. Ive been told time and time again that its my EGR or cat.
i am running two cats one on the stock mani and one new one down below. i got fed emissions. i am also throwning a CEL # 25, lean air/fuel ratio. does the EGR have any relation to this code. if my VSV or temp sensor for the EGR failed wouldnt i be throwing a code for the EGR. i applied vacuum to the valve itself and the engine stumbled and died like it should. i cleaned the injectors and filter too but im still getting the code and failing. |

id imagine that if the egr valve were stuck open, then that would be 'sort' of like a vacuum leak and thus cause a lean condition.
but if that were the case it should throw a code metioning ur egr... im not sure but thats my 2 cents --------------------  |
