2001 Ford F150 V8 Four Wheel Drive Automatic 260, 00 miles
Truck began to misfire, sputter while driving, idle really rough, loss hp. So I go to auto zone, they hook up the little tester, "misfire #7". I replaced the coil, problem solved. 2 weeks later, the same symtoms happen again. Loss hp, shaking, idle rough, sputtering when I drive. So I go back to auto zone today to hook up the tester again. He said it read.&Quot;lean on 6, 7, & 8. He told me I have a vacuum leak, not a bad coil. What do you suggest
have the same problem?
