i've have heard about this problem over and over and everytime i read up on it people says there is either a leak or your running to rich?? I wonder what causes this?

 

[luis monsalve]

well now it idles fine i lowered the fuel pressure and it idles perfect the next issue is after i boost when i come to a stop it does the same thing i can berly take off feels like i have a bad valve but is not am wondering if its still running to rich ?
help anyone

see if you can get it tuned that will solve everything

ur probably still 2 rich at idle

but ur real problem is what u chose as fuel managment

an afc with bigger injectors would be much better than an fmu
the ideal would be for u to convert to 0bd1 and run uberdata

if you ran rich you could of fouled your plugs easy, why not new injectors
granted you have a small turbo but your pushing more fuel through stock injectors still

and yes get rid of fmu it is junk...
