2005 Escape 3.0 with 160k miles. Slight miss under cruise, goes away under slight throttle. No service history known about vehicle. Best to replace spark plugs and coils with Motorcraft parts? And the intake gaskets too? Suggestions for correct plugs?
View 14 RepliesMy girlfriend has an 05 ford escape with a 3.0 the car has been well maintained it has 184,000 miles on it. Over 3/4 of the miles were highway. I have noticed that it has had a slight engine ticking noise i have researched and some say the tensioner some say retorque the cams? I have not been around these cars much. I replaced the alternator the other day and serp belt all pullys felt fine. The engine used to tick all the time here lately sometimes when it gets started it does it and sometimes it doesn't.
Also what fluid is supposed to be ran in the tranny the owners manual just says mercon, so do i just run regular strait mercon fluid in it? or does it need like mercon V. The car runs fine i just want to fix the ticking noise if its something major. Just some thing I've hear about on a buddys newer f150 with a 5.4 the oil supply ports that lube the timing chain tensioner got plugged and it developed a ticking noise? I am a mechanic so i can check and do anything i just dont know where to start on this car?
I have an '02 Escape, XLT V6 with 4WD. Recently (within the last month) we had to have the engine replaced. They found that three of the coil packs were cracked on the old engine. They put the new engine in, hooked it all up, and it ran like a dream. The new engine came off another Escape and has about 122K miles (the old one had 175K). Today, I got gas and hit the highway to visit family Up North for the holiday weekend. I noticed about an hour into my drive that the car had a slight chugging feel, nothing extreme but it felt like small catch. I got to my mom's house, and then drove with my sister to the gas station and she noticed it too, it seems to have gotten more pronounced. I noticed again really bad on the way back from a friend's tonight. It seems to 'chug' when pushing on the gas or in Cruise, but not when its just coasting. What could it be?
View 1 RepliesWhat to look for. 2001 escape 3.0 starts and runs but it has a miss and no codes came up yet . the engine will rev up but it really takes time to idle down . don't matter if its cold or hot it just don't want to drop to idle as fast as it should.
View 4 RepliesI 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 RepliesI have a 2001 Excursion with the V-10. Two weeks ago, the upper nipple on the radiator cracked and I overheated. Was towed home and replaced the radiator with a quality aftermarket one. I then drove to the whiz wash and cleaned the antifreeze off of the engine.
Immediately I noticed a slight "miss" when cold, particularly when backing out of my driveway. I have no lights on the dash and it is throwing no codes. The miss gets much better (almost gone) when the truck is warmed up.
I have a 2004 f150 with 135000 miles. Bought it a few months ago. I notice after the truck is up to operating temperature it seems to have a slight miss, you can kind of feel it when sitting in the truck. Cant really hear it. Outside the truck I am hearing a ticking sound. I have changed the spark plugs on the passenger side, because that's where the ticking sound was coming from.
Come to find out the last spark plug in the back was finger loose. Got them changed, on that side. Still have the miss after warmed up along with the ticking. Few weeks fast forward I put all 8 new COP on. Same results. I also have changed the oil and filter both with Motorcraft. Where I could look? I also have a 1 year unlimited mile power-train warranty.
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.
My second gen prius has slight miss/knock at startup. Done 35000 km. Doing around 19Km/Ltr. No other problem.
Any need for tuning, plug checking, needed at this stage?
I just purchased a 2003 F250 Super Duty with the 6.8L V10 It has really high miles on it as it was a landscaping companies fleet truck. I'm sure that it was pretty well serviced as it has 300K miles on it and it's still running pretty decent.
I picked up the truck and I have to get the smog done soon. It idles with what I can only describe as a slight miss and it runs and drives great. seems to have plenty of power for the miles that's on it.
There is no active CEL on but I scanned the OBDII system and found a P0171 Lean bank 1 code in the pending codes list of the scanner. I guess this year engine doesn't have an EGR Valve or DPFE sensor because I've looked high and low for it and there non existent on this engine.
I've checked for vacuum leaks by spraying brake cleaner or carb cleaner all over the place and it makes no difference and all the vacuum lines and connections look okay.
When it's running It does sound like a vacuum leak right behind the top of the plastic throttle body but I can't find it, I don't know if this big *** engine just sucks that much air or what.
Like I said I need to smog this thing soon and I don't want it to fail if it's missing or has another issue. The fuel injectors look new and one coil pack looks like it's a replacement...
Had this truck a few years now, and it has always had a slight miss/hesitation and maybe a few codes. The timing chain skipped a tooth and the truck was down for about a year. I have 4 other trucks, so it wasn't a big deal. I finally had time to put a new oil pump, chains, guides, tensioners, phasers etc. The truck actually runs very well and quiet. But, now misses far more than I remember it doing.
When driving in town constant at 25-30 mph occasionally it will loose power for a brief moment(<1 second) and then be fine, the security light on the dash turns on for a few seconds. It drives at 55-65 just fine, unless I am going up a hill or something else increasing the load.
2004 5.4 3v 2wd
CEL-
P0453 (fuel tank pressure issue)
P0351 (ignition coil a primary/secondary circuit malfunction)
P0356 (ignition coil f primary/secondary circuit malfunction)
The coil packs are new, and I have injectors on order. Also found this thing on the back of the motor, it connects to the fuel rail on the drivers side. Where it should go. I looked on my other trucks. But my other 04-4wd has a box by the battery it connects to, but mine doesn't have any of that stuff. And my 08 doesn't have anything like this at all.
And a pix of the truck in question.
Brought home tonight a 2001 Ford Escape 3.0L 24 Valve V6. Bought it from a mechanic who's customer didn't want to put any more money into it. Has 185000 miles on it and it throwing the P0303 & P0171 codes. Cylinder 3 miss and Lean condition bank1.
Mechanic thinks it is a valve seat in the cylinder head next to the fire wall. Before I start replacing the cylinder heads with new remanufactured heads I plan on doing a compression test and leak down test.?
Woke 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 RepliesI purchased a 2010 2.5 Altima with 9K miles in 2011. After @ four months I noticed a slight miss at 30-45 mph upon acceleration. I told the dealership and they said it wasn't throwing a code. After two more visits I again complained about the miss. At this time the service person handed me a "Customer Satisfaction Bulletin" that explained that cars (Altimas, 2009- 2011 with my trans. and engine experience this "SURGE" as they called it AND that it is NORMAL.There is no way in hell that a auto maker would produce a car that does what my car does and consider it NORMAL. Buy the way, there is a "FIX" that was done but didn't work, that involved changing motor mounts and computer programming.
View 8 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 RepliesThis last April I was towing my trailer back from camping approx 125 miles when I detected a loss of power and a slight miss. I managed to make it home. It wasn't until I made it home that the engine finally started coding. Miss on start, a couple of cylinders missing and output shaft speed sensor circuit failure. So naturally, I decided to do what I felt needed done anyways, change all coils and plugs. Oddly the problem got worse to the point where I almost didn't make it home after test driving it, it kept stalling out and was difficult to keep running.
After some research and advice from others, I started replacing some components; MAF sensor,IAC valve, output shaft speed sensor. Nothing. In fact now the truck wont move, I start it up it idles a little rough, but then I put it into gear and with in seconds she shuts her self down. I've replaced the fuel filter, checked the fuel pressure and it is in specs. I've now had it towed to two mechanics neither of which have any solution. They've put expensive computers up to it and still nothing. I really do not know what to do at this point. Lastly the only code that continues to come up is P0720, output shaft speed sensor circuit failure, I really miss my truck!
Im 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.
I have a mysterious problem with the BMW 335d concerning the engine. The dealer detected a "miss" in the cylinders based on the check engine light, but there is no real drive problem. However, I have noticed a slight hesitation and noticeable reduction is fuel mileage. They don't really know what it is but suggested replacing the fuel injectors, in case that is the problem. And if not, maybe it needs cylinder head replacement. That seemed to be a rather expensive (for me) way to diagnose the problem. I can't believe that BMW somewhere has seen this problem before.
View 4 Replies2003 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.
