my 1989 chevy k5 blazer will not idle. last summer it blew a head gasket, i replaced the top end and after that it stoped idling. I have checked timing, replaced rotor, cap, wires, plugs, throttle body, and still will not idle runs well when you give it gas just will not idle. i have checked compresion in all cylinders and have between 125 and 120 please help
