I drive a 1995 olds that has 125,000 miles. It runs like a dream but I have been having one problem I cannot pinpoint a solution for. When started cold, it runs and drives perfectly all day long, no problem. However once it reaches operating temperature and is shut off for a short period of time, it shudders and stalls upon restart. Then it does not restart until the engine is cool. The problem has been intermittent and not as much of an issue during the winter, but as spring approaches I worry it may become a bigger problem.
It has had a recent tune up: new spark plugs, wires, radiator, hoses, fuel filter, fuel pump, air filter, and water pump. This issue existed before all these parts were replaced.
Any advice or places to look would be greatly appreciated.
