when you get the sprrd up to 40 mph it feels like it starts skipping and you speed up it stops
Spark plugs have been changed and the coils have been changed too but the check light keeps coming on!!!!
Hesitates when driving on the freeway reaching 40mph. Jerking motion.
Vehicle driving poorly, stuttering and shaking. Service engine soon light came on. Took in for service and changed out two coil packs and all spark plugs. However less than two months later, same problem. One of the previously replaced coil packs was bad again. It was replaced again. But later that same day, still drove poorly and is once again getting worse by the day. Service engine soon light not back on as of yet.
The ignition coils are always going bad. Very frustrating.
All the plugs and coil packs were replaced now I have a knocking noise sound like it's coming from the intake
All of a sudden no power and my engine was backfiring. Had the computer checked and 3 ignition coils came up bad along with the oxygen sensor. No problems what so ever before this. Art Hill Ford quoted me $280.00/Ea to replace the sensors. WOW!! No Thanks. Checked on the part and they cost $40.00/ea plus you have to remove 1 screw to get the coil out. Takes about 5 min. per coil.
Check engine light came on and read #4 cylinder misfire at start-up. Shop replaced #4 spark plug and ignition coil. $250. Said rest of the spark plugs could be put off for now to save money.
Shuddering hesitation when accelerating and very low power. Check engine light went on after a few weeks of this(flashing initially, then full on). when I let it idle for 30 minutes, the engine light went off completely, but still hesitates badly. Others have said just replace the spark plugs. They apparently break often on this vehicle and minimum cost is $450 before using the tool specially designed to remove broken plugs, which I'm told has meant a $1200 tune up for others. I should also mention that I bought the truck 5k miles ago from Suburban Ford in Sterling Heights, MI.
hesitation when accelerating....all sparkplugs replced & coil...$850 at Ford!
misfire on #1 cyl code 301...changed plug 2months again code 301 misfire... changed coil pack... all good 6mo

One engine coil 2nd from back on passenger side keeps blowing up. I have not replaced all the plugs coil which would be ideal. But l am getting ready to replace that coil boot for a third time.
Purchased the vehicle December 3 20014 has a 3 month power train warranty on vehicle check engine light came on and started missing very bad called place where I bought vehicle they said to bring it in but 159 miles to dealership they gave me number of the wrecker service they used called them they towed it to dealership looking over paperwork they replaced number 5 spark plug and coil for same problem now it is number 6 spark plug and coil but charging me 790 dollars 450 for the wrecker and 340 for parts and labor so ill right now should be under power train warranty but they saying no
Coil pack was replaced all 8
Had to trade in because Ford stated that the motor was gone.
#4 keep misfiring cant afford to keep tuning it up evry 3,000 miles have to replace spark plugs.
While driving home from Wash DC on I95 noticed AC was a little warmer. Then while wife was driving the engine light began to flash and car felt rough, like a tire problem. Actually it was the misfire causing the shake. Could I have picked up bad gas? I just changed the fuel filter before taking this trip and changed the oil, checked coolant...everything everything was good. I stopped here in Fayetteville for the night, put in a bottle of techron fuel system cleaner and fresh 93 octane gas....hoping in the morning it is better, but might need to change the plug and coil pack on #7 cyl. I luckily had my obd scanner and it spit out the #7 was misfiring.
Skip and miss even while idol engine light on
