2004 Ford F-150 Heritage Problems
An illuminated Check Engine Light could indicate that one or more of the ignition coils has failed due to excessive spark plug gap. To fix this problem, the ignition coils that have failed, the spark plugs, and all coil boots should be replaced.
On higher mileage vehicles, one or more EGR orifice in the intake manifold may plug with sludge. This can cause the engine to misfire when first accelerating because too much exhaust gas is directed into the cylinders where the orifice is not plugged. Cleaning the clogged passages should correct this concern.
There is a technical service bulletin for the V8 engines regarding a possible problem with the spark plug being ejected from the cylinder head, damaging the threads in the spark plug hole. If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.

I had just changed my spark plugs and wires on my 2004 ford f-150 Heritage 4.2L V6, now it runs rough and shakes a lot. Never had issues until now, has over 145,000 miles, any help on how to fix this I would appreciate it.
this was the last year for this generation f150.changed the body style this year but still produced the heritage.all the bugs had been worked out in pryor years so i went with it .test drove new body style and i didn't like the ride.had this truck for 5 yrs now,and no problems what so ever.
I have an increasing problems #1 while just starting off it seem the truck hesitates sounds like the automatic transmission is changing gears then it takes off. #2 connect problem is connected to #1 while traveling at most any speed the trucks sounds like it's laboring or switching gears. If you step on the gas it takes off.
