1995 Dodge Neon

No, it did not surge or force the coolant out the overflow container prior to them working on it. I explained this to them and asked if it could possibly be the head gasket since a few of the manuals I have read suggest this may be a cause. They assured me that it wasn't the head gasket after the first visit. They replaced the throttle position snesor wiring saying it was defective ($350). This did not cure the problem. The next time I had it in they told me that the Throttle body would need to be replaced since their was a service bulliten out on it some years ago. They wanted $500 to replace it. I have had this car since it was new and told them if the throttle body was bad I would have noticed it long before now. I ran out of money to give them to replace parts and not fix the problem. I was told that if I didn't replace it that their was nothing else they could do for me. This was last Fall. We drove it over the winter and it wasn't too bad. Now that the heat is back its gotten too bad to drive. I thought this time I would try to find the problem myself prior to taking it to another dealer or service station. Before I started getting into the head gasket I was told that maybe the water pump was going bad. I can live with the surging problem for now but the car won't drive without coolant.
