Problems with response ...AAN transplated in NM Coupe quattro
Hallo ,guys!I hope you to help me a little bit..
So thats the problem...A have AAN motor in my Coupe and it's running good,but when i kick the gass pedal down it stops about 2-3000rpm and thinking what to do,then on 3000rpm the power cames and everything is OK!If i step on the gas slowly,everything goes nice.I'm with brand new fuel pump,lambda ,working TPS,MAF and ECU...We tested with few ECUs,MAFsensors and everything that could be,but it's doing this again and again....I have rich mixture gas/air.We think that possible problem may came from the electrical system,because the el.system was modified to rich tbe revert intake mainfold.Every part ,that may couse this has been changed!On the VAGCOM problems readed are MAF sensor and Lambda control,but as I say we have tried with oders ,who are working properly..??
I'll apreciate your help and I hope you to give me an advise!What to try??
