i have a evo 9 and i just had a motor put together from blowing my stock i got a block and with 58,000 miles on it stock daily driver and i replaced the rod bearing and crank bearings also piston rings now i left the used rods and pistons in cause i was just daily driving it and not worrying about power. well now its biting me in the but i didnt rebuild everything im having a issue with my car stalling. it started slowly doing it every now and then to everytime i push clutch in. now it only does it if i push clutch in fast or push clutch in while driving. now when the car warns up it starts back firing and the engine sucks rpms down till it dies even if i try keeping rpms up. need help guy so far i tried boost leak test and idle adjustment some other things. i believe it to be crank walk do to thrust bearing going out.

PS forgot to add that when i push the clutch in it makes the acessory belt sqeek im think its do to the crank being pushed over from pressing in clutch another reason why i think its crank walk. PLEASE HELP thanks mike

 

I think you are right. Check the thrust bearing.
