I have an 04 ltz and it started sputtering a little bit while going down the road and I was low on gas so I just figured that's what it was. But now I can't get it to start I completely cleaned the carberator put a new spark plug and coil pack in it and all it does is turn over. It has compression it's getting fuel and it is sparking but all it does is turn over any idea what it is??
