i have a 330i which i bought of the lot on my birthday in may 2005. Would you happen to know if they were defects when this car came out? my engine is acting up, the other day i was making a left turn and the engine revved up to 3 rpm all by its self and the shuddered a little and went back down to 2 and all that time i was barely pressing the gas i was jus lightly holding it down
