300 6 cylinder, engine missing with little power....

1 Answer


Check compression, they should all be close too the same, if not then you need to run a leak down test to see if it is rings or valves. How good are the plugs,wires,cap and rotor. Intake manifold leaking, carb falling apart. Broken vacuum lines, etc.
