there is no lag with accel when the car is working. When the issue is present it won't go beyond 1400rpm and it barely moves forward. Yesterday it did it 4 times and it also had a new symptom: it died and when I went to restart I turned the key 4 times and got nothing, nadda, not even a click. the 5th time I turned the key it started. The only part that has ever been replaced is the throttle body.
