Read the above posts and forum threads

Hey everyone,

There have been several excellent posts answering the question on this exact forum. I just went through this entire process myself, search my other posts for a detailed write up on transmission versus COPs. It starts with overdrive then progresses to drive....it feels like the car is being hit by something, let off the gas and the problem goes away.

I read every thread i could on this forum...by far the most common problem is:

1) COPs (Coil Over Packs) - mount directly to the spark plug
2) Spark Plug

Could it be the transmission or torque converter, yes, BUT until you do 1 and 2 above don't go there. A code will not always be thrown, it may turn on the engine light momentarily but self clear. I only registered a code once, all the other times were transient.

06 Screw, RWD Automatic. Mine was doing exactly this. 120,000 miles, bought used with 78,000. Replaced plugs and all coils.No hesitation, no slack, just gets up and runs now. Broke 6 of the plugs replacing them. Local parts store has the tool to remove them as a loaner tool. Was much easier removing the broken plugs than I was led to believe. I got the plugs(Motorcraft), and all 8 coils(generic) off of the Auction site(ebay) for a total of $150. Stealer wanted $499 plus $50 per broken plug to do the work. and that didn't include the coils($79.95 ea). Now to figure out why I get the fuel odor when I first start it up. Going to pull number 8 plug, and check to see if it's seating properly, Did get a CEL indicating a miss there....wiggled the coil and connections a little, and the CEL went away. Which kind surprised me. Was figuring I'd need to clear it with a scan tool, or disconnect the battery, but neither was needed.

I have an 06' with about 160k and i'm getting the same symptoms according the maintenance records the plugs & coils were done around 130k. I'm not sure where to start as it doesn't seem like a coil should be bad already. any thoughts?

plugs or coils. plugs are cheaper so change those first. if that does not solve the problem try coils. Mine was solved with just plugs.

If feels almost like I hit a pothole in the road.....but I know its the tranny jolting the entire truck. Furthermore, it only happens when overdrive is engadged and I press the gas just a little more, but not enough to make it down shift into 4th gear. I don't know if the tranny is trying to downshift and can't decided whether to or not, or if there is something internally wrong. Any information you can provide me with would be great.

At the moment this only happens when in overdrive. I fear that if I let this continue to happen I will lose OD completely or worse yet.....lose my entire transmission. What might this be due to?
Same thing here...took it to 3 shops including transmission shop and nobody can tell me whats wrong. The tranny place said it was not the transmission.

Coils. They're a pain in the anus. Not to work on, just living with. I just did 2 and I got at least another 1 or 2 to do. It makes the truck no fun when they break

05 f150 with 240,000 miles. Same problem, took mine to a couple trusted mechanics. Change all of the coil packs. Why risk another failing soon after you change a coue bad ones. Pick them up after market on Amazon for $8 a pop. The front plugs are easy to do, the back ones need more time but you can knock out the front ones quickly & hit then back ones when you have more time. Or, take it in to have all of the plugs replaced & bring in the coils yourself & have them switch them at the same time. Any reasonable mechanic will do them for no charge, they have to pull them anyway.

The "low grade" misfire doesn't throw a code, but the computer picks up the misfire & is sending information for the tranny to shift & you feel the tranny shift hard.

I've had lots of other potential big issues solved through these forums. Tefinke@yahoo.com
