2001 f150, v-8, 5.4, replaced coil on 7 because "misfire code". Ran good for a few weeks. Light came back on, little shake at idle, shaking and sputtering while accelerating, loss hp. Now have code "lean on 6, 7, 8. HOWEVER, it is running exactly the way it did when I had a misfire on 7. I was convinced I put the coil in wrong. But now it is a too lean code. I have cleaned mass air flow sensor, chwecked thuroughly for vacuum leaks, next im told I need to clean erg system. Is that right? It cant be fuel issue because its only 6, 7, 8. What do you suggest next
have the same problem?
