while in neutral, blipping the throttle causes the rpms to drop (car stutters, lights dim) before rising. it has also caused the car to stall once when blipping the throttle in neutral. Also, while crusing in gear then shifting into neutral, the rpms will drop down so low that the car stutters and lights dim again...then back to normal idle. I've tried ajusting the TPS sensor and changed my plugs but to no avail. any idea's what it "could be"? can anyone shead some light? thanks
