[QUOTE="xcrave, post: 512337, member: 21738"] Just a thought... do you guys actually considered Air filter? Ive changed mine to K&N drop in... ive seen and felt much better response from my engine... Maybe the MAF is not at fault... the air filter is blocking air to the engine (lean,rich) reading??? When cleaning the MAF sensor did you also clean the air screen too? BTW there is more than handful people out there who just ruined the MAF by doing the CRC MAF cleaning... hope this is not the case... as the saying goes, if its not broken dont fix it... Just my 2 cents... but MAF reading should be ok like what have been said... unless you are comparing to an M3/M5 charts yeah urs is wayyy off... Here are the reading i got from a forum friend **not a specialist or anything just direct from his own car reading** Depending on the Engine CC/ltrs/Etc based on his E46 323i 2.2K++ cc his MAF have the Approx of 11.36 - 11.47 kgm/hr at idle and with AC it should not be not more than 16 kg/hr (he's is 14.65 - 15.2 kgm/hr) or its a sign of failing MAF. Resulting to shudders and stalls... loss of power is the most obvious sign Im not sure myself just sharing when i show him Jarance graph he said its neither bad or good... could be bad he said, then again hes also not a specialist... so yeah show to specialist better than guessing... beat the forum purpose tho but at least it will not be so much confusion as there are already is...
