2013 Ford F-150: misfire or rough idle

Filed Nov 19, 2022 · Acceleration, Engine · OR

When attempting to coast to a stop at slow speeds the throttle stays up and even causes the truck to accelerate at times. The truck will shift hard randomly. The truck appears to get stuck in a high gear and loses power to accelerate, at times. Driving at highway speeds the truck loses power. A mechanic shop pulled codes p0720 and P0722. The mechanic shop referred me to the dealer because the codes were under an extended warranty for a recall 16s19-supplement #1. The dealer reported that they did not pull any codes off the truck except finding erratic misfires. The dealer reported that the truck engine light has to come on for them to read a code. They reported they can not order the lead frame part until they pull a code off the truck. They also report the part is on back order with no ETA. The trucks wrench light continues to come on but not engine light. An auto body shop was able to pull P0720 code off my truck without the engine light coming on. Ford has not returned my calls.

We own a ford f-150 3.5 l ecoboost v-6 king ranch pickup truck. Truck was purchased in 2014 new. Have serious concerns as the vehicle has so many current issues. From day one of purchase and while still in the dealership parking lot, upon start up there was a very loud clattering sound. Sales rep said it was because it was cold and it had been sitting. Purchased vehicle, had problems immediately with dangerous lag in acceleration (which we still do), an average of 12 mpg if we were lucky and very serious engine misfires with major decrease in power accompanied by sputtering whole vehicle shuddering while trying to merge on the highway or with hard acceleration. Very dangerous, especially if in the fast lane, which we were. We started to limp over several lanes of traffic to the shoulder and the truck regained power. Many misfires like this, all explained to the ford service tech and verified on the trucks computer. So many in fact it was necessary to replace all spark plugs at less than 57k miles. We just picked our truck up today, feb 18th, 2020, after it was in the shop again, this time for 12 days, to fix this misfire problem again and numerous other issues with the front hubs staying locked in 4 wd while in 2 wheel drive and switching in and out, timing chain replaced, and the ecoboost turbo tubes replaced as they were cracked, iwe replaced, and left front actuator. Also about 3 weeks ago it had transfer case motor replaced as well as numerous switches, all which did not correct the problems. My husband and I decided to take it on the highway to see if the lag misfire problem was fixed. When he hit the gas there was a screechy sound from the top of the engine, power seriously decreased once again on the highway and the check engine light was back on. I sent an email to ford and auffenberg ford in ref to these continuing problems.

I have a 2013 f150 and have a loud noise coming from the engine. After my mechanic looked into it he said it is the timing chain rattling at start up. The truck has only 52000 miles on it. Barely broke in and now has a rough idle and loss of power when driving. My mechanic came up with 4 different codes showing camshaft and crankshaft position correlations. Turbo charger under rest. System to rich bank 1 & 2 and misfire detected at start up. This is a 2013 truck with 52000 miles and ford is telling me it probably isn't under warranty and could cost around $3500 or more to fix. I see they have had problems with this same issue with the 2011 & 2012 f150s. Internet is full of this same issue. How can they get away with it for 3 years and no recall?

Ford f-150 3.5 v6 ecoboost stalls out at excessive speeds. While trying to overtake another vehicle the truck misfires because of the intercooler cools the air to cold to evaporate the condensation and hits cylinder four which cases it to misfire which then cause the engine to stall. Ford knows about these problems but does not notify the customer about the potential of it happening to people purchasing the vehicle. This is a major safety issues!

While driving on a highway, I went to pass another car. The transmission downshifted, and the RPM increased, until the engine/car began shuddering and slowed down, with the check engine light blinking. I was able to pull off the highway at the nearest exit, and after a period of time in idle, the engine regained its normal idle speed and operation. Checking codes pulled up a p0302, indicating a cylinder 2 misfire. No issues were found with the spark plugs, coil or cables for cylinder 2. This is a dangerous failure that appears to be affecting other owners of this truck, and could cause potential for injury or death, if the engine stalls at the wrong time.

I experienced a condition noted in ford tsb: asi-32166 "some vehicles, with turbochared gasoline direct injection engines, will exhibit flashing malfunction indicator lamp, an intermittent stumble and/or misfire during hard acceleration during extreme humid or damp conditions." while driving at a relatively steady 55-60 MPH (on a rainy afternoon), I pushed the accelerator down in an effort to overtake a vehicle. Immediately, the "check engine" light began flashing, the truck began to shimmy, and I started to lose power. Unable to accelerate any more, I promptly exited the interstate, parked, shut off my vehicle in an effort to allow it to "reset". When I restarted the vehicle, the check engine light was off and the truck ran fine. I was (thankfully) unable to replicate the scenario on the remainder of my drive home.

Multiple times now, my truck will downshift and send the rpms over 4500 this causes the engine to misfire, the engine light will blink and the truck will struggle to maintain its speed and any acceleration is extremely diminished. This is extremely dangerous as I frequently drive on rural 2-lane(one in each direction) highways and find this problem significantly impacts my ability to safely pass slower vehicles. It has failed to accelerate enough times that I cannot depend on the truck to accelerate when I move into oncoming lanes of traffic. At 30,000 miles the engine developed an oil leak. Within a month of having the leak repaired at the dealer, the engine experienced a major misfire event causing the engine light to come on. I returned the vehicle to the dealership for repair. The dealership explained that two ignition coils went bad and required replacement. This caused damage to the spark plugs for which I was charged approx $250 but was able to negotiate it down to $140. Within a month of getting the vehicle back, the vehicle started displaying the misfire symptoms with diminished acceleration and blinking engine light. Very unhappy with this vehicle's performance!
