I have a 2013 F150 4x4 with a 6.2 and it has a slight miss at idle. It's done this since new and over the 20kms it has now I've been given the round around on it from 2 different dealers. I'm told there is no code so they can't do anything. I'm thinking maybe a coil? Or perhaps injector?
View 6 RepliesTruck has a slight miss at 65k when in 6th at low rpm and also when sitting still. Wanting to replace the spark plugs. The truck has Motorcraft CYPS 12Y in it which shows up as SP519. No one carries those anymore. What's the next best thing?
View 12 RepliesJust bought my 2013 Ford F150 Supercrew 4x4 on Saturday. I noticed a vibration at 35 to 45 mph. Its a slight vibration, the whole truck kind of shakes. Really annoying for a truck with less than 200 miles.
View 14 RepliesI have a 2013 F150 3.5L Ecoboost XLT and have recently experienced a slight noise on acceleration in first gear. Sounds like a light rattle or ping. The dealer says it may be due to carbon buildup (I have noticed that the exhaust has a lot of soot on it). They are suggesting some additive to resolve this and she mentioned that the problem starts to show up at about 30,000kms. It does not affect power or cause misfire as described in posts.
View 4 RepliesLast time this truck did this, I replaced the #27 fuse and it started right up. This time, no such luck. It is EXTREMELY frustrating to pay this much money for a truck that you cant start. Btw, it has 38 miles until its on empty.. Any way that could be the cause if i am parked in my drive way which has a slight incline?
View 3 RepliesI bought a 2009 f150 5.4 with 150000 miles on it. I have a slight hesitation from idle so I want to clean the throttle body. I found several for the older f150"s with the horizontal throttle body but this 2009 has a vertical mounted one. I change the air filter and cleaned the MAF but didn't change anything. My wife's ford 500 had this problem and cleaning the throttle body completely cured it.
View 3 Replies5.0L ... I'm having one of those moments, you know after you do a mod to your truck and all of a sudden you notice something about your truck that could have been there all along but now you notice it as something new? Ok earlier in the week I had my exhaust resonator removed and replaced with a straight-pipe by a reputable exhaust shop. IMO the work looks to be pretty good for what it is.
That said I have always been nervous about getting exhaust work on any vehicle because it always seems like tampering with or removing the OEM plumbing for aftermarket or custom work tends to develop a vibration at some point.
So here is what I've noticed over the last couple days, when driving my truck it is extremely smooth, almost like glass. When I come to a complete stop say at a traffic light about 1-2 seconds after making the complete stop I feel this slight harmonic vibration in the steering wheel. For those of you that have an iphone it would be like having your phone bolted to the steering shaft somewhere and it on constant vibration if that makes sense.
Just to prove it only happens when I'm sitting still and idling in (D)rive I sat in my driveway with the truck idling, set the park brake and released the brake pedal holding the truck in place in (D)rive with the parking brake. No vibration, smooth as glass engine idle, as soon as I put my foot back on the brake pedal the vibration comes back. It's as if the extra draw of applying the brakes puts an extra load on some sort of accesory drive or componant under the hood and the result is this harmonic vibration.
Just so everyone knows, the vibration is very noticeable to me because I drive the truck daily, most people wouldn't pick it out if I didn't tell them first. Case in point if my wife drives the truck she can't feel it unless I tell her what to look for. There are going to be some of you that just say my truck doesn't do this and has had a smooth idle for XX,XXX miles I believe you but let me know now that I have explained exactly what to look for. Like I said for all I know it's done this since day one.
I have a feeling that the straight pipe might have been welded in slightly longer than the oem section that was removed thus putting more tention on the exhaust and engine if that makes sense, the end result being a slight vibration?? I know that manufactures put these little rubber bushings along the exhaust system on cars/ truck to absorb harmonic vibrations and for all I know my resonator might have been designed to balance out harmonic vibes in the exhaust system as well as quiet down the exhaust.
I posted a while back about my 04 5.4 having an issue at idle. I did all the normal things like replace coil, spark plug, etc etc. No change to the issue. It still acts as though it's misfiring on a cylinder and I get codes P0306 and P0316. Finally took it to ford and had a diagnostic check ran. Everything on the top end was in working order. The tech even put a known working coil on 6 and nothing changed. I was told that it's either an intake or valve issue on that cylinder. But no definite answer to problem.
Fast forward to yesterday. I got a wild hair at lunch and went out and started truck. Pulled injector plug off of 6. No change to the way it was running. I did the same for 5, 7, 8, 1, and 2. All of which made a big difference in the way it ran. It was obviously misfiring with no fuel to cylinder. This gave me the idea to swap 5 and 6 when I got home to see if the issue followed the injector from 6. I did NOT. I pulled the plug on 5 and got the obvious change in the way it ran. So there is definitely something going on at cylinder 6 that I cannot figure out.
PCM, bad intake, bad valve? I'm not rich so a trip to ford for repair is gonna have to wait. Truck seems to run fine when driving except for slight hesitation during acceleration.

I have a Rough Idle & sometimes a hesitation or stumble on acceleration. I cleaned the MAF & IAC motor & Air & Fuel Filters are new. I got a 20890 scanner & ran test 6 53 as suggested in many posts by BlueGrass. Here are My results & what They Convert to.

I'm guessing the cop's are ok & probably need plugs? I was hoping to just swap a coil. Too cold to do plugs & truck won't fit in my garage.
2013 3.5 Ecoboost. Starting the truck first thing in the morning, it idles very rough for about 30 seconds and then smoothes out. If I drop it into gear it stays rough as I back out of the driveway. Once underway it runs fine and otherwise runs/idles very smooth for the rest of the day. Doesn't appear to have any other symptoms of spark plugs/boots misfire so I'm thinking it might be something else?
On my old 02 F150 with the 5.4 this usually happened when the Idle air control (IAC) would get plugged up with carbon. I'd clean it and the idle would smooth out. This truck doesn't appear to have one.
Spark plugs are on my list for the near future. 47k on the truck so they are almost geting due. Trying to get my superduty sold before I spend a lot of time on this truck.
Got a 13 f150 with the 5.0. I bought it used with about 14 thous kms, now it has 17. Ever since I owned it I noticed the idle was a bit jumpy warm or cold. I didn't really pay any attention to it as it wasnt throwing a CEL or anything but now that I have a roush exhaust and intake I have started to notice it a lot more....not that its worse but at idle my truck sounds like a boat. Weird comparison I know. It seems like it'll jump within +/- 200 rpm @ idle which IIRC is 1K rpm.
View 7 RepliesWoke up to go to work and it started up with a rough idle, got a block down the road and it had a slight miss under acceleration. Guessing its a bad coil, I've got a spare featured I'd play I I mini miny moe when I get home unless.
View 5 RepliesEarly 99 7.3. Runs ok has a slight miss at idle however every injector when unhooked makes a change. Has white and blue smoke From the exhaust. Has enough blow by to blow the oil cap off as your unscrewing it. My question is, I know engine restore is bad for these trucks but I can't afford to rebuild the engine. If I run the restore and then clean the IRP once the truck dies is this going to mess anything else up. Do you think it will by me a few months to save up for a rebuild
View 9 RepliesIm a newbie to the Camry's. Picked up from a relative a 07 Camry for $5k. It has 103K on it.
It has an issue to where it has some codes and the check engine light on with P0018, P0019, P0300, P0302, P0306 codes. They just all cam eup al lof a sudden while driving. Slight miss at idle which is the misfire codes but I can't pinpoint the issue for the P0018 and P0019 codes.
2003 passat wagon 2.8l v6 with p0421 and p0431...a slight miss as well...
Cold start up is fine and initial driving. After car warms, there is a slight shutter at idle (just occasionally) and upon acceleration with low rpms. (It really feels like a miss) Went to AutoZone and came back with the codes above. I thought it might need a new coil but now I am not really sure. I want my performance back but seriously doubt cats are bad at the same time.
On a 2000 F-350 with 5.4 engine, where does the vacuum line enter the cab? I got a truck in with no vacuum signal to the heat controls, and it has a slight miss at idle. Both of these are signs of a vacuum leak, but i can not find the line going into the cab.

View 4 RepliesOK, 4th time in a week that my truck has had this problem... Seems to only be when the truck is already warmed up, restarting after sitting for a few minutes. Starts up just fine, but as soon as I drop it into gear it begins to stutter and stumble, running rough as can be and absolutely no throttle response. I have to kill the engine and restart the truck for it to correct itself, but the restart takes up to 5 seconds of extended cranking to finally fire up. Today is the first time I actually got a CEL and a code: P0078. Only had the truck 8 days now...
View 13 RepliesI have a 2013 F150 (8 cyl), 4 wheel drive, 110K miles, original brakes. Last week with the cold front coming thru Houston my truck started to make a very low moan when ever I turned right at low speed. It does not happen every time I turn and there is a slight vibration I can feel in steering wheel. Tire pressure is good.
Per my Dec 2016 inspection I still have 20% left on my original brake pads. I've read this could be ABS related, steering column related, etc. I cannot locate any areas where the tire might be rubbing. What I am dealing with?
F150 EcoBoost. Last week in PA we had temps. Above 90 with humidity and dew point in the seventies. I tried to get out every afternoon and drive around. I did local and highway running. I had no problems at all with the condensation build up in the CAC.
Either this truck is not going to have that problem or it is the terrain of w.PA. This place is so hilly that you just can't cruise around for a long while and I like to hammer the throttle a lot. Truck was built 9/9/2012.
On those hot days I could feel a slight tick in the steering, barely noticeable really. This week it cooled down and I went to the same place at the same time on the same road and there was no tick in the steering.
