So we have a 2002 Pontiac Sunfire, 2.2 litre. Bought the car, used it not even 24 hours later the battery light came on, did a multimeter test, showed the alternator was bad, bought a new one and changed. Worked good for approx a week. Now the battery light comes on and off. When the battery light is on, the wipers are slow, the stereo quits working, when idling the rpm's will drop down and before stalling jump back up, all the lights on the dash will light up (battery, abs, e-brake, airbag etc.), the speedometer and tachometer will quit working also. ANY IDEA WHAT THIS COULD BE??? 3 Answers

2001 Pontiac Sunfire engine noise. The noise can be described as a ticking noise that accelerates with additional throttle. Engine cylinder head was replaced right before the noise began. I have already replaced the oil with little luck. The noise seems to start when the engine warms up and quiets down at high speeds. Any suggestions. 11 Answers
