I got a problem I've had this 94 camaro z28 for a while now and I've put a lot of money into it and it runs great but for some reason after about 5-10 minutes of driving the check engine light always comes on and then this loud fan like blowing sound turns on for a few minues and then it goes off It repeats this every 10-15 minutes It sounds like my engine is trying to cool itself off and when I shut off the car you hear the engine shut off and then you hear this fan noise wind down just like when you shut off a vaccuum cleaner I don't know what the problem is Can anyone help

 

hello the names Mike. Check your Vacuume lines and you fan motor. W/b when you do this.
