No nothingg happened to the car before it started to play up. I first noticed it not long after i addded my manual boost controller in. I have it set on 10 psi atm but its still doing the same becasue i thought that could be the problem but i guess it wasnt. Im using the platinum spart plugs im pretty sure its bosc that make them well there pretty exspensive and they are alot better than what was in there before lol.
Thats what i thought that it could be the fuel pump but i wasnt 100% sure and didnt want to waste big $ on getting another one if it wasnt going to fix the problem
