Take the pipes of one at a time and put your thimb on one end and blow down the pipe as they can go pourus

ok and finally when you first start it is there any smoke coming out the exhaust. Also have you had the car on a diagnostic machine

[inventor1958]

NO SMOKE AT ALL RUNS SMOOTH NO TO DIAGNOSTIC

try changing the engine temperature sensor unit. When the engine is cold this is what tells your ecu to give it less air l(like a choke) and as engine warms up it gives more air, Sometimes when faulty these units cut of to early
