Verified

The engine may have a misfire, hesitation, and/or run roughly – notably after a service and/or ignition wire replacement. If after recent ignition wire replacement, the cause can be misrouted ignition wires. The wires from the distributor to the valve cover must be routed correctly to avoid interference and induction crossfire. Verify all clips are used to secure and separate ignition wires.

    Engine would misfire during acceleration, especially between 35-50 MPH. Just got it back from Ford garage after paying $800 for repair. Replaced EGR & another part. Then found a sparkplug wire that was laying against manifold and had burned and was shorting. Picked it up from the Ford garage and it runs worse than ever. Now it also 'shudders' at times at stoplight like it's going to stall out.
