Hi again

the car seems to pop through the air intake then dies when it boosts up. It holds boost at about 8 psi. Its been doing this for about 2 week now I've replaced the spark plugs, cleaned the fuel pump filters checked for air leaks as best as i can. its just brought the E M light now and the traction control light up

any help please

your t4 comes with vvti cam? check again the timing mark.
