Prius (Gen 2) :: Scangauge - DTC Code And / Or Freeze Frame Data
When I use the "scan" feature of my Scangauge II, sometimes the DTC code and/or freeze frame data will change on me. That is, I check it and it says "1 stored code" (without clearing it), then go back to "Gauge" and then check the scanning function again, sometimes the code has changed to something else! With the freeze frame data, sometimes it will even change as I'm scrolling through the different data fields. Very disconcerting....

I would like to understand what this reports mean.

So I am working on my 5.4 I pulled and discovered that is is very oily behind the freeze plugs. The motor is on a stand and has been upside down a few times. There was still a little oil in it as I can see a decent puddle under it where I didn't tighten the drain plug entirely. Why would there be oil built up there? I have the two from the back of the heads out and the two on either side closest to the rear of the block. What kind of issue am I looking at? Here is the build thread that I am doing about the truck and this motor.

Honda - Accord :: 1997 - Weak AC With Mist
As you can glean from Discussion Title, I have a 97 Honda Accord that has been weak in producing cold air with the a/c on since we bought it three years ago. The car has been the "third car" for kids to drive so not a big deal. Now that one of the "kids" is commuting this summer to an internship, the hot car is a problem. I drove the car this morning as I just drive to the train, and noticed mist coming out of the dashboard vents when the a/c was on. The mist stopped when the a/c was turned off.
Does this misting mean we have an evaporator core leak, or other problem? It certainly doesn't seem like just a freon boost is needed. If the evaporator core needs to be replaced, how bad a job is that? I replaced one in a '72 Plymouth Duster once and didn't seem so bad.
Ford F-150 - 1997-2003 :: New Transmission - Poor Acceleration
So I was given a 1999 f150 4.6. The transmission was supposedly either new or rebuilt. (I'm going with rebuilt) Driving it for the first time today, I noticed it had very little poor acceleration. When I would get on the gas (to the floor) the rpms would shoot up (3-3.5) but the truck didn't accelerate accordingly. It feels like the power it's getting to the wheels. Driving at highway speed trying to maintain a speed at over 70 the truck wanted to stay at 2500 rpms but if I let off the gas just a touch it would shift up (into overdrive I think) and level out at just below 2000 rpms, but if I accelerated even just barely, it would down shift and go back to 2500. I've also noticed the truck runs 5 mph faster than it reads with stock sized tires. I've check the tans fluid and it is bright red in color and at the appropriate level. I crawled under the truck and noticed the trasfer case mount was wet with fluid (not dripping) and the rear output shaft of the transfer case was also wet. Could this be a transfer case problem?

Need some input on miss firing on acceleration on a 2001 Ford SuperCrew F-150 Lariat, 5.4 engine. 200,290 miles.
Have replaced all spark plug boots covers (Sept 2012), number 1 plug (Sept 2012), 3 and 7 plugs replaced, 3 and 7 has heli-coil kits (2011) installed for blown out plugs. New in-take manifold (2010). New gas line filter, air and oil filters (Oct 2012) and oil changes every 3000 to 3500 miles. Have poured 12 oz. fuel injector cleaner in gas take two times with 6 to 7 gallons of fuel in gas tank (last 2 weeks).
Have No check engine light on for service engine but have had an diagnostic scanner analyzer plugged into driver side, in cab outlet, 4 different times to see if I have a bad coil on plug or other problems. No codes show up indicating any problems. The engine idles nicely when at stop lights but does have a slight intermittent miss at times when warmed up and stopped at lights. Engine misses when warmed up on acceleration (when it is under a load and on acceleration).
Had a mechanic tell me he could plug an analyzer into engine but couldn't guarantee he would find anything wrong. This sounded like a little snow in July to me and the mechanic didn't sound optimistic.
Ford F-150 - 1997-2003 :: Violent Shaking Under Acceleration
I've had this truck since 2011. Ran great when I got it. Ive had problems with the calipers and I've replaced both the fronts. I keep up on changing the oil regularly. The manifolds started rusting away a little over a year ago. Not happening... The shaking started recently after I pulled a trailer with 2.5 tons of shingles on 2 separate occasions.
That being said, I can feel a little shaking while idling. It was really only bad between 500 and 2000rpms. After 2000 it almost felt like a turbo and it would accelerate really fast and smooth until the gears switched. I figured i should change the oil. Now the shaking is more violent.
Its a 2000 f150 5.4 v8....
Ford F-150 - 1997-2003 :: Bad Miss Under Acceleration Below 2500 RPM
I have a 97 f150 with 4.2 4x4 auto. I have a bad miss under acceleration. if i ease on the gas no problems. stomp it and it chugs and pops back thru airbox til it gets to 2500 rpm then clears up. If I shift it manually and keep rpms up its fine till it gets below 2500. I have replaced spark plugs, plug wires, fuel filter, upper and lower intake gaskets, cleaned injectors, new air filter and cleaned o2 and mas sensors. Had vacuum system checked and was told all good.

I have a 2001 F150 4x4 5.4l with 105k miles. I started it up today to go to lunch and it made a knocking sound on start up that lasted maybe 20 seconds. So i shut it off and checked oil. All ok. Started it up again and it knocked but not as long as it did previously. I started to drive and higher in the rpm range before the trans shifts it makes the same knocking sound. Left off the pedal it goes away then rev it again it doesn't make the knock till around 2000rpm mark it I remember correctly. It makes the noise in all gears, parked or driving. It runs great, no power loss or misfire. Could it be a spark plug on the verge of blowing out or is it time for a new motor? I am going to look at it more tonight when I get off work.

my 97 f150 4.2L keeps stalling on acceleration. It ran fine this morning then my wife put 20 dollars of fuel in it and drove 30 miles to her destination with no problem. on her way back the truck started bucking bogging down and acting like there was a fuel problem but it didn't kill. I checked for codes there were none. I removed the fuel filter on the rail and replaced it with a new one. Now it will idle fine with no miss but if I give it gas it kills.
I checked the codes again there are none. I also checked to make sure there was fuel coming from the tank when I turned the key as well as making sure I heard the fuel pump kick on when I first turned the key.I am leaning towards water in the fuel,i didn't see any trash come out of the old filter, however I am not sure. I have a 175 mile commute to and from work.
Ford F-150 - 1997-2003 :: 2001 - Shudder And Surging Upon Acceleration
When I first bought my 2001 f150 a few mos ago there were no problems but I did notice once in a while it would give one little shudder when id accelerate. now all the sudden it shudders after around 20 mph all the way up to whatever the speed limit is. Then it smooths right out until I have to accelerate again. if I punch the gas and kick it down it will clear up but then it feels more like a surging going on.
I had the cruise set at 70 the other day and I had to slow down to merge to around 50 and when I hit resume it really started shaking bad and the service engine soon light flashed on and off for a few minutes then went off and hasn't came back on again. I took it to advance auto and no codes showed up. they said its probably the torque converter but after reading multiple forums I am not so sure now.
Ford F-150 - 1997-2003 :: Ticking Noise Would Be At Idle Or Under Acceleration
About a week ago my 1997 F150 4.6L 2WD starting a ticking noise. I had used high mileage full synthetic Mobil 1 and a Motorcraft oil filter for the previous oil change and yesterday had another oil change using regular Mobil 1 synthetic and a Motorcraft oil filter. Had never used high mileage oil before.
Since the high mileage oil is supposed to have extra cleaning agents in it to remove the sludge buildup in the engine, could the sludge have found its way into the oil pan and possibly clogged up the oil pickup tube? The ticking was not continuous and would be at idle or acceleration.
No rhyme or reason to when you would hear it. I also wonder about an exhaust manifold leak which could sound like ticking. If the problem is an oil pickup tube being clogged up, can the oil pan be removed with the engine still in the truck?
Ford F-150 - 1997-2003 :: Engine Went Into Rough Idle / No Acceleration
I have a 2000 F-150 5.4 L. I was driving from home and seconds after the engine went into a rough idle that wouldn't let me accelerate. I scanned it and gave me multiple transmission trouble codes, about 15. I checked the wiring, the transmission fluid and it all looked good. So, what could be the problem?
View 3 RepliesFord F-150 - 1997-2003 :: Knocking At Startup / Screech On Acceleration
I am going to start from the beginning because oftens times we don't provide all of the information that may be pertinent to the correct diagnosis or repair. It'll be kind of lengthy! It all started about 3 days ago when my wife told me that my truck was "shaking." I said, "ok, just drive the car til' I can look at it" The next morning, the I was able to look at the truck. I had a cylinder 8 misfire detected. I drove it for about 1 hour that day to and from work. I did this so I could see what what the "shaking" was. It was actually what I describe as a "shudder."
Anyways, I done a fuel pressure check and all was well. I took of the coil, tested it, it was fine. So, I took out the plug to inspect it. It was wet! Not drinched, just mildly damp. I dried it off, cleaned it off with carb cleaner and it fired right up no hesitation no nothing. No CEL light, no shaking, no shuddering. It ran perfectly normal. I let it warm up to speed and took it for a test drive around about 6 city blocks. All was well. So I took it on the highway for about a 2 mile stretch. I was givin' her some juice pretty hard to see if it would misfire. Upon acceleration I heard a screech. Now this is where it get's interesting.
The screech that I hear, I just related it to the belt because it's done it ALL the time. When I first bought the truck it squalled like a whipped puppy cause of a cheap belt. The good ol' bar of soap trick fixed that! But, ever since then, it upon shifting, or under acceleration it would screech then stop. So anyways, on the highway run, it screeched while I was accelerating. It did this from about 60mph-80mph. I then, turned around and came back home. By the time I got to the stoplight to turn off towards my house my oil light was on and the engine was knocking. Not a tap, a knock.
I slowly coasted home not going over 20mph and pulling it out of drive as much as I could. I get home, and I check the oil and there is nothing on the dipstick! WTF!? I always run Mobil1 Full synthetic and put it 6qts. It doesn't smoke, doesn't leak or nothing! So I freaked out and went and bought 2 qts of Valvoline Hi-Mi and poured it in. It brought up the hash marks and quieted the deep knock. Later that night after work, I done a full oil change and flush and put back in my Mobil1 Fully synthetic 5w20. It now knocks at startup, and smooths out to a tic. Then at idle, it sounds like a light knock. It appears that it goes away upon acceleration.
Ford F-150 - 1997-2003 :: Vibration Under Hard Acceleration From Stop
01' Screw 5.4 4wd. Went camping this past weekend and it was the first outing for this truck our TT weighs 6k. When accelerating from a dead stop going straight I'm getting a rumble strip like vibration that last a second. If I take off very easy it doesn't do it. I've seen similar post but no definitive solutions. This truck has less then a 100k on it and so far I've changed the trans filter/fluid rear end oil with modifier and new spark plugs.
Once I'm rolling and hammer down it won't do it. It's more of a annoyance then anything.
Ford F-150 - 1997-2003 :: Acceleration Hesitation / Cannot Get Passed 2500 RPM
97 f150 4.6 4x4, no check engine light, no missing or sputtering, however when I try to get going I can't get passed 2500 rpm and when it finally does its still kind of sluggish and can't pass as easy. Changed fuel filter. It idles fine and when I put it in neutral it will go up to 5000 rpm if I want.

I have a 97 F150 4.6. The truck has developed a slight stumble/misfire when under acceleration. Once at speed it runs fine. It has not given any codes. I've checked for them several times. The plugs and wires have been changed. Is it possible that a coil pack could be bad without throwing a code?

My 03' 6.0l hpop only makes about 1700 psi at wot, at hot idle the ipr is 25.1 and the icp is about 580. It runs pretty good but it seems the crank time to start is getting a little longer sometimes, other times it fires right up. It makes no difference if its hot or cold. Do pumps get weak or do you think I have a leak?....
