i have a 1986 bronco i hooked a compression tester onto the first spark plug valve on that front of my straight six engine and its only showing 30 lbs of pressure on the tester....what possiblities am i looking at to fix here...could it be a blown valve or something else? when truck is running, and the spark plug is in the cylinder valve, when i take off the distributor wire from that cap theres no loss of power, but when i dissconnect the others, there is loss of power. please help with all your possiblities and how i can fix it. we checked all the other cylinders and they're fine the spark plugs are new...
