Don't get me wrong, this car has been great to me! bought it a year ago with only 95k miles on it, but right away a problem started. If i filled the gas tank more than halfway, the car started to seriously hesitate when accellerating, sometimes even stalling out completely. Being the impulsive and poor young college student that i am, i fixed the problem by never filling the tank more than halfway. Well, problem's gotten worse (imagine that!) The car more or less hesitates all the time now, especially badly under 3k rpm. The car also stalls out intermittently, and seemingly randomly. Suddenly the throttle will just stop responding, and the engine will slowly wind down until it stalls out. Sometimes i can just put it in neutral (at which point it'll stall out right away) and after about 20-30 second of coasting pop the clutch and it'll start right up, but most of the time it starts back up with the same problem. I have to pull over, wait 2-3 minutes, and it starts right back up again. Yet, throughout all this, it doesn't give up a single error code. I've replaced the fuel filter, and i added fuel injector cleaner, my next bet is probably going to be to change the fuel pump and hope for the best. Any ideas?
