hey guys so just needing a little help here. lately my crank broke in half. withought damaging anything, so we relaced it with a brand new forged crank and a new set of bearing. while we are at it i decided to do a different turbo setup. my old setup was just an fp red. my new setup is a 6262 t3 jb with an ets manifiot. tiak wastegate on a ver low psi spring. we finally got the car running. and here we go driving around to break the motor in. not hitting boost just cruising. some times when coming to a stop the car likes to die. it only hapens randomly. i give it a little gas for 20sec then its fine. my afrs read a little lean when it does that, any one might know why?

 

anyone?

 

Vac leak? I would check to make sure all your lines are okay. Pcv valve will do that too.

 

i just went under there and took a quick look. since im just breaking the motor in i used a vaccum line fron the wastegate to the turbo and i found out it was ripped in half. would that cause it? its too late at night now and i dont have a spare line

 

are you on MAF or Speed Density?

 

i am currently on maf. once all the problems are figured out it will be on speed density

 

This could be a number of things starting either with the tune and/or you must check your idling components to see if they are clear of debris. Good luck.
