My 2005 4.6 supercrew is worthless for short trips.....I am freezing and pick any other ford to drive.....my v10 heats up totally in 5 minutes so I know something is not right.....I have changed the thermostat....( its been like this since new ) the fluid levels are perfect....what is up ?
View 14 RepliesI have an 05 150, 5.4l, My truck idles around 600 rpm when warm, I think that may be slightly low. Not sure what to check on.
View 1 RepliesI have a 05 fx4 5.4L with 85k on it. It has started idling rough when i come to a stop light or slow down to 10 mph or less. It only does it once in a while. There doesn't seem to be any real pattern. The motor shakes until you rev it up and then it goes away.
I have cleaned the maf, put in new air filter and fuel filter. And put in a new battery. Would a coil act like that? Maybe plugs? Or a vacuum leak?
I have narrowed down my starting issue to a faulty relay(409). When I pulled the relay and cleaned the contacts and reinstalled the pump primed and the car started. Car will idle for about a 1/2 hour and out of the blue it shuts off. If I try to restart, 9 times out of 10 it does not start. If i tap the relay, it starts right up. If the car is running and I tap on the relay the car stutters and if I tap it again it shuts off.
View 10 RepliesThis happens not all the time, can cold start and the car runs fine but then once its shut off then started for use again later it will shut down, sit on roadside for 2 minutes with key off and then restart and good to go again...its a random thing...the check engine light does come on...
View 11 RepliesJust replaced the starter and battery on my old but loved 4Runner. I drove it for an hour and a half last week and couldn't restart it. Just nothing - one click I think. A friend tapped on the starter and it started...but I'm not sure whether the car just cooled down at that point. Took it to the garage and they said they couldn't find anything wrong (no surprise, right?) Now I'm afraid to take longer trips.
View 2 RepliesMy GC is overheating. Started as occasionally but now increasing in frequency. I find it will being to overheat after driving on the interstate for half hour or so but I can "calm" it back down but turning on the heat. I've replaced the following:
1. coolant (no drips or leaks nor am I losing coolant over time)
2. thermostat (twice)
3. temperature sensor
4. serpentine belt and tensioner
5. radiator (last summer)
6. water pump (last winter)
I notice the fans run more often than they should. For example, after a 10 minute ride to work in the morning,. I notice the fans are running as I pull into my parking space.
I have been having a brake drag problem with my '89 Jeep Wrangler. I posted this problem previously when I thought it was an E-brake issue. I did a rear drum spring set change. The problem persisted, so I asked the local auto parts store and they said it could be a faulty master cylinder which I just replaced. The brakes felt fine for the first 1/2 hour driving, then the pedal started feeling harder to push and the brakes were dragging again. I jacked the car up and removed the tires to find both front calipers tight on the rotor, the rears would spin. With someone pressing the pedal, I did not notice any caliper movement.
View 5 RepliesI've had this checked out twice by the dealer and once by another mechanic and they say there's nothing wrong ....
First symptom: the heater will start out hot but about a half-hour into my trip into work it significantly cools down. I'm not sure if it's starting out too hot and cooling down appropriately but I think not ... it gets downright cool at 70 degrees.
Second symptom: I sometimes smell coolant in the passenger compartment, usually while I'm operating the heater. However, in these last bitter cold days I've smelled it when I get into my cold car in the garage in the morning.
Third symptom: I have a film on the inside of my windshield on the lower one-sixth or so ... it gets very cloudy, particularly when I circulate air to the windshield or turn on the AC to defog. I've asked three times to have the heater core checked and they all say it's fine.
I have a 2003 rav4 with about 100000 miles on it. Over the last 4 months I have noticed that, whenever I drive half hour or longer on the highway the car starts to smell like burning rubber or burning antifreeze or something like that. I live close to work, play, and groceries, so I don't drive it that long very often. I have not noticed decreased levels of any of my fluids. No change in performance either. I've had the oil changed regularly and no problems there. I am about to drive it a thousand plus miles and would love to get this figured out before I go.
View 7 RepliesI noticed through careful investigation that my 03 GTI 1.8T (180,000 KM's or 111,850 miles) will grind 3rd when in these conditions:
1. When the car has been driving for more then half an hour and everything is hot
2. When the car is over 2800 RPM's while hot (ie. getting on a highway)
Now I know lot's of people blame syncro's and yes I could see that my car has had 8 previous owners so I can't say they all shifted perfect. But what I do know is that when I downshift from either 4th or Neutral it will never grind even when I don't Rev Match or "Blip" the throttle. So it can't be syncro's in my opinion.
So what I've done to the car to rule out some problems were:
- Change the gear oil from what ever it was before to Royal Purple 75W-90 (NO luck.)
- Then I added a short shifter and adjusted my cables properly (still No luck)
- Finally I noticed my shifter was sloppy and one of my bushings were torn so I bought 42 DD's metal bushings and the shifter did stiffen up a lot, however!!! (No luck)
I know it's not my driving technique because I watch my foot depress the clutch fully and then I gently push it into third. I also know I'm shifting correctly because I can double clutch and normally shift through every other gear properly without any grinds or clunks. Just the devilish 3rd gear.
I would like to hear the solution. I'm going to change the oil one more time to Redline MT-90 and see how that goes, but if that doesn't work I might just tear apart or get a new tranny.
I have a 2004 F-150 and the gas gauge seems to be stuck on a half tank, sometimes it will go to full tank. How do I fix this.
View 3 RepliesI have a 2004 F150 4x4 5.4L and with one front tire off the ground, truck running, when you spin the tire the half shaft turns with the tire, it does this on the left and the right when I have either off the ground. I did it with the truck running because I heard that when it is running it disengages the hubs. My question is why do my half shafts turn with the wheel in 2wd with the truck running?
View 6 RepliesI have a weird issue on my 2008 Elantra. The heater starts blowing luke warm/cold air after running for about 1 hour or so and stays like that.
View 9 RepliesMy 2004 with 5.4L Lariat is struggling to keep me cool. The AC works fine on mild days but when it gets into the upper 80s it works for about 10 mins then goes warm. If I shut down the AC for about 5-10 mins. it begins cooling again.
I first tried a retail charging kit with no improvement. Then I had the system drained and refilled with die to look for leaks, but neither had any immediate impact. So it is not a leak, but something else failing.
What are the next best troubleshooting steps for an AC system?
I'm having issues with my a/c blowing randomly warm air. At idle (stop lights, heavy traffic) the cold air will kick off but the fan will remain constant. Once I'm back up to full speed, the cold air will come back. It also works if I turn the a/c and fan off for a few minutes and turn it back when I'm at highway speed. I've recharged it and when it blows cold it will freeze me out. I'm thinking its a possible compressor issue?
View 6 RepliesI have a 2006 Ford F-250 5.4l the symptoms are when it's warm it has half power and it will stall at idle. What I have done with the truck is.
New cam phasers
new chain
new tensioners
new vct solenoids
new oil pump
new plugs
new ignition coils
new stock cam shafts
new rockers
new lash adjusters
new exhaust manifolds both sides
new muffler
oil change with the right oil
ran it with sea foam in the crankcase before oil change
new fuel pump module
new evap vent control
new abs speed sensor
I cleaned throttle body with brake cleaner ... Scanned it after a 15 min ride of having to use 2 feet to drive it. The engine codes that came up are p0022 iacv short to ground and p1000 readiness test not complete. I also got p1804 4 wheel drive high indicator circuit failure p1808 4 wheel drive low indicator circuit failure .... Not sure what else to try.
so im a fairly new owner of a 2008 f150 lariat 4x4 5.4l3v bought in September of 2013 with 32358 miles. this engine was built in 10/9/2007 and was just before the spark plug update so I have the black cop on this engine. and on cold day start ups it sounds like a diesel till warm and then it still has a slight knock to it vary slight is this normal or is this a tall tail sight of the phaser issue or spark plug issue coming to light love this truck and will fully rebuild it if I know what to do, ford dealer says that its normal and that if I lose power at some point I will need a new engine with this low mileage.
View 14 RepliesI purchased an '08 F150 about 6 months ago, and have a problem that two mechanics haven't been able to solve. The truck has a 5.4L engine. Unfortunately, I bought from an auction and the 30 day warranty expired before I realized the problem.
After a longer drive (30 minutes to work) the engine is warm, and I always back into my parking spot or driveway. In low gear, it begins to idle very rough and the engine shakes. If I leave it long enough, it will stall. Usually I pop it into neutral, give it some gas, and its fine. I just bought a camper trailer, so I'll need to use the lower gear when backing up.
So far, the engine has been flushed twice, the solenoid replaced and phaser replaced. The second mechanic has recommended I contact a dealer, but haven't had luck with them with my previous Explorer. What it could be? I will be getting the diagnostic paperwork this week.
History: Truck was running okay but acted like a coil was bad when under load. I changed out all the plugs with Motorcraft and put on Summit racing COPs.
After the plug and cop change the truck will run rough after it is warmed up. I changed back to the old COPs and it runs the same.
First I replaced the MAF sensor after finding many posts on here about it. No change.
I read a bunch of posts on oil causing the problem so I used 10-30w and nothing changed.
I searched for a vacuum leak with carb cleaner and couldn't find one. I removed, cleaned and reinstalled the throttle body.
When I did the plug change I disconnected the PCM without disconnecting the battery. Would this cause this type of problem?
I think this is about all the stuff I found to try in the threads that came up through searching.
I have 2004 f150 small v8 (4.7?) Has about 92000 miles.
When warm truck runs excellently. At first start up the idle is very rough and raw gas smell for about 4 minutes then truck runs like new. Will start and restart great until it cools down overnite.
My actron says missfire cyl 3. Did not fix it. Dealer says that on start up compression is zero in cylinder three but is 100% when it warms up. Suggested I run seafoam through it. He thinks it has a vacuum leak or carbon at start.
In my limited knowledge I am thinking:
sticky lifter
bent push rods
warp valve
