I have k04,FMIC,MBC,BOV,CAI,new maf,new spark plugs. Well its been running great ever since last week ive been researching and tlking but nothing the same as my symptoms. I figured out how to triger it, i put it in tip go into 3rd gear pull up to 4500 rpm and let go of the gas and then it dosent say 54321 it says PRND432 and the D is let up just like normal,turn off the car and its all back to normal. I can drive thru town like normal driving and its ok but once i get on it it goes into limp mode i think. Once it goes into limp mode it jerks wen it downshifts, and sucks at accerlation takes forever.Its still drivable but u know somethings wrong. Any ideas?
