Hey guys i signed up for this one question; my air fuel ratio is so wako it bounces my idle is terrible bounces from almost a stall (an some times does ) to 1100 rpm and when you are driving if i push my pedal over 20% the afr drops to 9.9!! Not to mention that my afr’s are bouncing too anywhere from 11.5- 19.8 and everywhere in between I replaced my air filter wich was sevearly due for a new one and it made it worse i know i need a new tune but I figured before i spent alota money on a tune that might not even work , i would ask some experts and those who possibly had similar issues. Oh yes and there is no engine light currently one poped up and i deleted it (p0109) it stated high maf voltage i googled it and it didnt give me much
