I have a 1993 base camaro w/ 3.4l v6. I had the car looked at and it had a bad coolant sensor . i replaced it and it ran fine for a little bit now it wont start. Before it would run really good then after awhile it would rev up andf idle at about 3k, if i give it gas it just dies no missing or anything just dead. if i let off before it gets to low then it will go back to 2-3k. it stalled and now it wont start. i have brand new wires, plugs, TPS, and coolant sensor. what in the heck could be wrong??
