I own a 95 Caprice Classic 4.3L V8 Engine with 130,000 miles. The car start great, runs great when started, however, when the car reached the operating temperature, the engines will just dies with no symptoms at all.
When restarted, the engine will hesitate,jerk, buck,runs very rough and dies, its a stop and go and dies condition at this point.
I have to let it cool for at least 1/2 hour and it will run great and then the problem cycle again.
I replaced the ignition module and fuel filter but it did not help. The fuel pump was replaced 14 months ago.
I am going to replaced the Engine Coolant Temperature Sensor this week and hope this would sold the problem.
If anyone has similar problems in the past or knows what the caused is, please e-mail me.Thanks
