Question about 2006 Ford F-150

Open Question

While driving, the engine has a slight bucking or hesitation, but is not a consistent thing. Give it gas at highway speeds and everything runs fine. No indicator lights come on at all? Vehicle has 100K miles... wondering fuel filter, had a mechanic mention something about a torgue converter fluid, and I realize maybe a tune up, but I worry about the plugs on the ford breaking in half and dropping into the motor.... dealer says they are not responsible for this happening and all expenses to remove it are mine

Sounds like you could have a bad coil or boots. When I do tuneups on fords I always use motorcraft plugs, and replace the boots that hook to the coils, also buy some dielectric grease to put small dab inside the boot where it slides on the plug. You will probably also need 8mm socket, 7mm socket, and a wobble spark plug socket, or swivel to reach some of them. I usually try to blow air around the intake to clean any dirt off. Then I do 1 plug at a time, and while the plug is out i crank it over or start it a second to blow anymore debris out. Fords are bad about getting misfires on back cylinders. If you take it to a shop beware book time is about 3.5 hours. Could be worse I just got through last week tearing apart a 6.0 powerstroke in 2006 E350 (No access there)

Only thing that comes to mind with description is maybe heat shield on exhaust, getting loose. Wait until vehicle is cooled off and get under there & check any heat shields you see wrapped around or near exhaust, above it attached to floor of vehicle etc, and give them all a little shake or rap with rubber hammer or similar to see if any rattles are present.

SOURCE: engine runs rough at idle and bucks at highway

I had a similar problem in a 1994 Taurus, and after spending nearly 300$ on ignition parts, it turns out the problem was a bad spark plug wire that cost me 8.88$ to replace.

Could be fuel system related, especially if it has dual tanks. Have you tried the T.P.S? (throttle position sensor) Its usually located under throttle body.

2006 mazda mpv runs with a lot of hesitation while driving. Used spare key runs better but not perfect

Its most likely the spark plug ignition coil(s). There's six. These cars will run forever until they throw a code for which one(s). You'll see lousy gas mileage too. What you can try is drive at a steady speed up a long hill. It'll buck a little but it'll give you a code. #4,5 & 6 are in the front of the engine from passenger to driver's side. #1,2 & 3 are at the back of the engine from passenger to driver's side. They're about $50 each and mine usually go bad one at a time. I'm on my third round of replacing these things.

Engine misses/hesitates on low speeds. Runs fine

is the check engine light on? have you ever serviced the injectors? if not try that first because there are many things that give the symptoms you spoke of. but this is the cheapest.

2004 5.3 K1500 with 46K miles. Bucks and hesitates at highway speed. in 3 or OD. Runs fine at idle and running to highway speed.

Could be your fuel filter is plugged if you have one. My 2005 doesn't as there are filter screens in each injector. Find a buddy with a reader and go for a test ride with it plugged in. There are too many possibilities to mention
