Did you check the intake and throttle body. Maybe a oily sensor and when it warms up it gets clean.

alexmartinez

Thank, I clean the maf and trottle plate yesterday with no luck. Does it have other sensor to clean?

SilentJoker

Maybe cats issue hm... Hard to say without an odb reader the first mins are open loop fuel etc to warm it up. After its running and in gear stomp on it does it miss or stall? Does exhaust feel pressure coming out or little?

My manifold have some leak since few year.odb no code.

Phaser.? Can he have not much pressure at start? But if i dont touch gaz he run on choke well.

Do you have an obd reader? Can you see your timing and maf readings?
