Suburban :: EGR Code After Driving At Sustained Speeds Above Forty Mph
94 GMC 5.7 K1500 .... I have been getting an EGR code after driving at sustained speeds above forty mph. The code gets stored for say less than thirty starts then disappears until I hit the highway again. I took the EGR valve off, cleaned it with carb cleaner (really soaked it) until all the black crud stopped coming out, replaced the gasket and reinstalled it. Back on the highway and the CEL is on again (goes out after a few minutes/miles) and the code is back. I went to the auto parts store and got them to show me a replacement valve. When I shook it there was a slight rattle (which I assume is the diaphragm). On the other hand mine offered no rattle sound after cleaning so I'm wondering if the valve is pooched. Anyway my question: whether the problem is
a) the valve,
b) the solenoid or
c) dirty EGR passage in the manifold?
Depending upon the cost of the diagnostic (ie if it exceeds the valve) I'm probably going to just go ahead and replace it. I don't need a smog test until next Spring.
Ford A/C :: Blow Cold And Then Hot / Work Fine Only At Highway Speeds
'99 Exp. My AC blows cold most of the time when I first start the car, after awhile it begins to blow hot (heater hot). If I mess with the switches for awhile it will blow cold again at least for a little while. It appears to work fine at highway speeds, but if I stop for a light, it starts to blow hot again as soon as I take off. You can hear a flap close (or open) sometimes when you move the switches. I have read several post concerning the blend door, but I don't know how to check to see if this is the problem. According to my manual, I have to take apart the dash to get to the blend door. Is that correct? I would hate to go through all of that only to find out it is something else.
View 6 RepliesSierra :: 96 - AC Only Get Really Cold At Highway Speeds
I have a 96 Sierra with the 5.7L (R) engine. My a/c used to work fine...no problems. Then it started to only get really cold at highway speeds, plus you could also hear the compressor running (kind of making a clicking sound) when you push the a/c button to turn it on. I thought that the system needed to be recharged, so I bought a recharge bottle at Shucks that has a low pressure gauge on it.
It says that the low pressure port is the larger of the two and will only fit on the low pressure port, but it will only fit on the smaller port (right side port when looking at the compressor). With the a/c on max, the gauge reads 110, so I didn't try to recharge the system.
Then yesterday, my a/c won't even cool at highway speeds. It just blows warm air. The compressor is running (I can hear it, and the clutch turns). I disconnected the switch on the evaporator and the compressor stops, then restarts when I reconnect the switch.
Ford Excursion :: Front End Hum At Highway Speeds
This weekend I am planning to do some major repairs to my X, she is a 2004, Limited, 4X4, 6.0 PSD with about 130K. I am planning to replace my wheel bearings, axel seals, and upper and lower ball joints. Some of these are just maintenance items that I will be replacing since I am already there and others are in hopes of eliminating the hum I am experiencing at highway speeds.
I am looking to purchase the Moog ball joints along with the wheel bearings (which I believe is my noise maker). I am going to replace the axel shaft seals because the right side was leaking when I purchased the X in August 2013. I might even change the front brake pads since they will be removed at the same time, all depends how worn they are.
What else should be replaced?
Ford - Fusion :: 2010 V6 Stalling At Highway Speeds?
My daughter's 2010 v6 Fusion has stalled twice (without warning) in the last month at 65+ mph. The dealer reported that since no fault codes were set, there were no repairs they could make to correct this very dangerous situation from recurring. What repairs were made to correct the problem. The car has only 23k miles and has been well maintained at the dealer.

View 3 RepliesFord F-150 - 1997-2003 :: Overheating At Highway Speeds
1999 F150, 6 cyl. 4.2L, 233,000 miles. My temp gauge went way high on the interstate so I assumed I had a bad thermostat. replaced it with a genuine Ford themostat, added coolant and here's where I'm at.
1. Let it idle up to operating temp. When it was warm, the heater was blowing cold air.
2. Thermostat opened up, top radiator hose was hot and full of coolant, still no heat in cab.
3. Took it for a ride on the hwy. Heat started to work in cab, temp gauge went way up. I slowed down and went home down a side road. Temp gauge went back to normal and stayed there. Only driving about 30 mph.
I don't get why I'm overheating at 60mph. My best guess is I have some sort of obstruction in the cooling system.
Ford - Escape :: 2004 - At Highway Speeds Transmission Shifting Up And Down?
I have a 2004 Ford Escape XLT, auto,V-6, with 129000 miles on it. It runs fine except for a couple of things. One is, at highway speeds the transmission will seem to shift up and down. Also sometimes at highway speeds I get what I describe as a "bump" or "shudder" I think it is coming from the transmission.
View 4 RepliesFord - Explorer :: 1993 - Intermittent Shake At Highway Speeds
A friend of mine has a '93 Explorer 4x4 with an automatic. He's getting an intermittent shake at highway speeds. It shows up every 5-10 minutes or so. Apparently the problem has been going on for a few months now. I took it for a test drive the other day, and it feels similar to driving on rumble strips. It shakes in both 2wd and 4wd, but he says it seems worse in 4wd. The vibration feels more like it's coming through the seat than the steering wheel. The vibration will go away if you take the foot off of the accelerator, or if you pull it down into Drive. He's got about 220K miles on it. The previous owner said the transmission was rebuilt about 30K miles ago, but who knows. He's had it in the shop for a couple of days, and they've checked the usual suspects - u-joints, ball joints, and the sort.
View 6 RepliesFord F-150 (2009-2014) :: Vibrations At Highway Speeds 55 MPH Or Higher
Lifting 09-13 F-150 with the two piece drive shaft. I am getting a lot of vibrations at highway speeds(55mph or higher). I have a Pro Comp 6 inch lift that was installed while I was stationed in Alaska. I have the drive shaft spacer that goes on the drive shaft at the pinion. I also have a carrier bearing drop kit from BDS that I am currently experimenting with (trying to find the sweet spot). I am at a loss though because my truck is no longer fun to drive. I drive an hour to work one way and it blows that my truck feels as though it will rattle apart. I have tried doing all the research that I can find about this issue.
View 14 RepliesFord - Explorer :: 1998 - Knock / Thump From Rear At Highway Speeds
I have a 1998 Ford Explorer 4X4 two owner and only 63K miles. All service records including tranny flush. Tranny shifts fine, there are no "clunks" when shifting out of Park.The only symptom is an occasional bump or thud ( maybe more like a jolt )coming from underneath at the rear at highway speeds. Sometimes it is more pronounced than others. I don't believe RPMs change when this happens. Around town is fine and only at constant speeds above 55 which makes it difficult to recreate. I have checked for anything loose underneath ( incl spare tire ) and can't find anything.
View 3 RepliesFord - Explorer :: Fairly Pronounced Bump / Jerk At Highway Speeds 65 MPH
I have a very well maintained 1998 Ford Explorer 4.0 SOHC 4X4 with only 67,000 miles. Sometimes at highway speeds ( 65MPH ) there is a fairly pronounced bump / jerk. I will also happen occasionally when accelerating from a stop. IMHO, it's not a slip. Fluid has been flushed and is bright red. The best I can tell the RPMs are not jumping when this happens. I've all but counted out an engine misfire. There are no engine or OD light on. Where I should begin troubleshooting? I don't want to spend tons of money trying to isolate the issue but this Explorer is in exceptional condition so I want to have it fixed.
View 8 RepliesFord F-150 (2009-2014) :: V8 Transmission Hard To Shift At Highway Speeds
I have a 2014 screw 4x4 v8 that has been in the shop 5 times now for something that the dealership can't duplicate, and that is intermittent enough for me that I can't determine what the conditions need to be in order to duplicate it myself.
My transmission will shift hard under two different situations:
1) when rolling through a stop, or a momentary stop at a stop sign, the transmission holds up between 3 and 1, and when I bring the rpms up, the transmission shifts down into 1, making a hard clunk;
2) at highway speeds, more so when using cruise, if I accelerate and the truck shifts down from 6 to 4, there will be a hard shift as well. In fact, when I'm on a long stretch of flat, open road using cruise at 70-75, I can feel a slight bump through the steering wheel and floorboard, as if the cruise is trying to engage the throttle a bit more, but only for a split second. But that will happen quite a few times within a couple miles until I come up on a grade and the throttle has to engage for a bit longer to keep speed. Sometimes, the hard shift will do occur going to 5 as well, but 90% of the time it will be a 6-4 shift. If the truck decides to shift from 6-3, there's no issue and it shifts and accelerates like it should.
Again, this is so intermittent, but when it happens, it happens several times. I've had the service tech ride in the truck with me, all the while not being able to duplicate the issue. I understand that these are learning transmissions, so the only thing I can think of is when I try to duplicate it by accelerating over and over, that the transmission adjusts the shift pattern or fluid pressure to compensate.

My 1994 Aerostar, with 100,000 miles on it, started lurching at highway speeds. Weeks before this, the airbag light began blinking. The transmission man said it felt like it was shifting into overdrive, then out, then into overdrive, then out, etc.,etc. About this time, the cruise control quit being reliable. Dealership said codes didn't show a problem, "I must be mistaken". Then they said it sounded like a fuel filter.
View 6 RepliesFord F-150 (2004-2008) :: 2007 - Vibration And Noise At Highway Speeds
First, details about my truck. 2007 F150 SuperCrew, 2wd, 5.4, 203,xxx miles on it, leveled with Hell Bent Steel 2.5" kit last year, has been aligned professionally since then, tires are good and balanced.
The issue I have is a vibration, kind of the same feeling when driving on a road surface that has had the top level of asphalt removed before it's resurfaced. It's mostly noticable at highway speeds. Its not a violent type vibration, but you can feel it. There is also a sound, similar to tires with a deep off road type tread.
The sound and vibration more noticeable when making lane changes or when wheel turned towards left, at highway speeds, not as much to the right. I've checked front wheel bearings, they are good, zero play, no loose suspension parts, u-joints are good, no leaks anywhere.
Since it makes the noise and vibration a bit more when moving wheel, could it be a power steering pump? The pump is the original.
