Ford - Explorer :: 2000 - Consistent Knocking Noise Increases As Engine Speed Increase
I'm looking at a dirt cheap Explorer 4.0, has been sitting for 2 years. Runs nice, with a double "knock" noise but quieter than a rod knock. Idles smooth at 600 rpm, "knock" is consistent, but increases as engine increases speed. Has 2 year old oil, and 2 year old gas. Would a tune up support it, and revitalize it, or is the engine almost dead. Still drives, didn't push it to hard. Interior is 9/10, exterior is 10/10. I have him down to 600. 4x4 works, and feels good.
View 6 RepliesDodge - Neon :: 2000 - RPMs Go Up But Will Drop Back Down When Speed Increases
I have a 2000 Neon with about 170K miles on it. with in the last 2 weeks it has been having a problem with acceleration. When i start to drive the RPMs will get up to 4 before it will start to move. Also when i am drive and need to pick up speed the RPMs will also go up to about 4 before it starts to pick up speed, but will drop back down when the speed goes up. I have found a little oil in the spark plug tubes and will be changing the seals out, and I have cleaned to MAP sensor as will. What is going on with my acceleration.

I recently had my 2002 1.8T in for clutch replacement at the dealer and they came back and said the crankshaft was bad ( the car was occasionally making noise when pushing the clutch in, they thought it was a throwout bearing) I took the car back to bring it back to an indie, and it is loud at idle and while accelerating (sounds like a chattering noise that gets faster as speed increases) It's now sitting in the parking lot. My question is, am I going to have to put in a whole new engine to fix this problem? can just a crankshaft be replaced?
View 2 RepliesChevrolet - 1500 :: Oil Pressure Goes Down As The Engine Temp Increases
I have an 88 Chevy C1500. It started showing low oil pressure about a year ago and I went with a heavier oil and oil pressure go a bit better.
Just changed the oil and now, when I start the engine cold, I show normal oil pressure. As the engine temp increases, the oil pressure goes down. When engine is fully warm, oil pressure shows 0 and "check gauges" light comes on.
Decided to put even heavier oil in but guy at parts house said it was probably the sending unit, not a worn out engine. I tend to agree because I drove it more and never hear any ticking or valve noise. Too cheap to replace the sending unit.
From the symptoms above, does thus sound right? Could the sensor somehow fail as engine temperature increases? Everything I read says oil pump failure is very rare.
Honda - Odyssey :: 2004 - Engine Whine That Increases In Pitch With RPM Or Speed
Recently had my 105K maintenance done which was water pump and timing belt plus whatever other misc belts go with that. Had it done at an indepentdent shop. Since the job was done we have noticed a high pitched whine that increases in pitch with RPM or speed that we drive (literally sounds like a jet engine whine). I took it back to the independent shop and he suggested it was our transmission. I have noticed no difficulty when changing gears nor any engine warning lights. I contacted Honda and our vehicle was part of a transmission recall in 05 that was done already. Other sources have suggested that the whine could be the belt being too tight or the water pump. Shop supposedly used all honda parts. Should I take it back to him again and suggest that the belt is too tight? Take it to the dealer and see what they think?

2000 passat GLX, tip, 2.8L v6... new brake pads and freshly turned rotors, but both the "ABS" light and the "BRAKE" lights come on intermittently whilst driving. It doesn't happen every time it's driven, just maybe 1/3-1/2 of the time, and it is only on for a bit before it turns off, but it will usually turn on again later for a short stint as well.

2015 F-250 Super Duty, 6.2 L Gas with 6r140 Transmission. I have 13 K miles on my truck. While pulling my travel trailer up a hill the transmission kicks down thru the gears, which is fine, but as I crest the hill and in 2nd gear, the engine begins to rev up and the speed increases, the transmission will not automatically go into3rd gear. I have tried to let up on the gas pedal, but it remains stuck in 2nd gear. I have to shift to "Manual" and then put it in 3rd gear. Then it shifts up as it should. I have tried with the transmission in "TOW' and not in "TOW". I have even tried it in "Cruise Control".

2000 Ex 5.4 v8
Had 2 coils go bad last week. Got them replaced. Today I am on the turnpike doing 70 and my oil light comes on and oil pressure drops all the way. No engine noises and temp is OK so I coast to the next exit. Get off and go to the gas station in the corner. Turn the truck off...
Wait a few minutes, when I go turn it back on it wont start. The motor wont even turn. It just clicks.
I notice smoke coming from the wire that goes from the starter relay to the starter so my brother comes and gets me and we go to the nearest auto part store and buy a new relay.
Replace it and try to start it, same thing. Just clicks and smoke. My brother gets under the truck and taps the starter as I try to start it, no go. I am fearing the engine locked up. But no engine noises, clicks or clacks or anything. Battery is fine as well. Any thoughts on what else I can try?
Caravan/Voyager :: 2000 Van Jerks Hard And Speed Drops At Highway
My van just started to have this issue today with jerking real hard like its dropping a couple of gears while going between 50-60mph. It is a 2000 with the flex fuel 3.3L 4 speed auto.When this happens the spedo will go from 55mph to 40 instantly while keeping a steady speed and it feels like the tranny is going to rip right out. This will happen every 5 to 10 min but go back to normal driving after 3 sec and has not popped any codes. It runs like a top and all fluids are at the correct levels. I have to commute 50 miles a day to work so i really need to figure this out!!!

View 5 RepliesPassat (B5) :: 2002 - Engine Warning Light Came On With A Misfire Whilst Doing 40 Mph
I have a 2002 Passat 2.0L petrol (130bhp AZM Engine), with single DIS Ignition coil pack. The engine warning light came on with a misfire whilst doing 40mph (no previous warning or indications of potential problems), which is present at all engine speeds. I had the code read, indicating a misfire on cylinder three. I have completed the following checks:
1) Cleared the codes and restarted engine.
2) Replaced the spark plugs with new ones.
3) Old spark plugs were in good condition with no oil, no deposits and the electrodes in good condition.
4) Checked HT lead condition and found no corrosion, a tight fitting cap and no damage to cable.
5) Earthed the HT lead and have strong spark when engine turns over.
6) Checked the injector electrical connections with a bulb tester and all is fine.
7) Removed the fuel rail and extracted cylinder 3 injector.
8) Performed a visual inspection of injector with all looking good and no blockages at the jets.
9) Tested the injector on the bench using a 12V battery to ensure it opens and closes correctly.
10) Replaced the injector in the rail and turned the engine over to check for blockages, with all injectors operating.
11) Swapped cylinder 3 and 4 injectors (misfire still on cylinder 3, no change)
12) Inspected fuel and air connections and ensured no leaks.
13) Checked the engine oil condition with no evidence of water contamination (head gasket).
Passat (B6) :: Transmission Drops / Picks Up A Gear When Driving Constant Speed On Flat Roads
Recently it feels like the transmission is 'hunting' drops a gear, picks up a gear when driving constant speed on flat roads. 2.0T with tiptronic. Additionally, very intermittent, the car will get a shimmy around 48-50 mph. feels more transmission related and it is not the tires since it is an intermittent issue.

have a 98 rodeo, with a V6 & Auto trans. have an intermittent problem - as I am driving engine will occasionally drop to idle speed and then pick back up to driving speed. Engine keeps running smoothly, just at idle speed.
CEL does not come on / no codes
Replaced Throttle Position Sensor - and thought I had found the problem, but since it is so random, it just didn't happen again for 1 1/2 weeks.
Mazda :: 1997 - Engine Race Then Chug And RPM Drops At High Speed?
I have a Mazda 626 (V6) with about 150K miles and a funny engine racing problem. It occurs only when I'm going highway speeds (for me, 70MPH) and the car has been running for about 15 minutes. The engine will race, then chug and RPMs will drop down again, then it will race, etc. If I slow down, it will stop racing, but often start again as soon as I put my foot back on the gas pedal. If I don't get on the highway (running 60MPH and under), the car is completely fine.
I've taken it to my mechanic twice; the first time had the fuel filter replaced, the second time got new spark plugs, but it's still doing it. What else it might be?
Ford Super Duty (1999-2016) :: 2006 F250 V8 - Knocking Noise In Engine And Oil Pressure Drops
While driving today, 2006 Ford F-250 5.4 L V8 138,000 miles , I experienced a problem. Started with the truck acting as if it was running rough, possibly missing. This was approx. 10 Minutes after starting. Checked the dash, no warning indicators and all gauges were normal. Approx. 4 more miles, the oil pressure alarm signals and I see the oil gauge has dropped to zero. I pull over, turn off and check the oil. Oil is clean and at a normal level. I restart the truck and the oil pressure goes back to normal.
Rev the truck up while sitting there and after a few seconds i hear a knocking noise in the engine and oil pressure drops again. Call the tow truck, driver used to be a mechanic . He asks me to start it again and the same thing happens. If you start it and let it idle oil pressure seems to go up to normal with no engine noise. Finally get to the mechanic and he calls me later saying the oil pump and screen may need to be replaced or the engine may need to be replaced.
Prius (Gen 2) :: Braking Pressure Increases When Brake Is Pressed To Stop
I recently picked up an 05 that now has about 101k miles on it. When coming to a stop if I put my foot on the brake and hold a steady pressure the car increases the braking pressure drastically once it's under 10 mph and the car jerks you forward unless you let off of the brake. I know its because its going from using the regen to using 100% disc pressure so what can I do to fix it?
View 9 RepliesCamry :: Gen 5 Steady Sound That Gets Louder As Speed Increases
This is a 2002 Toyota Camry 4cyl with 249157 miles. I drove it 140 miles to work, noticed no issues, parked it, and got back in after 10 hours. On the way back I noticed a noise that got louder the faster I went. It is independent of the engine revolutions (I put the car in neutral and "coasted"). The noise is completely dependent on the speed of my forward movement.
So I put the car up and in gear and around 25/30 mph, the sound shows up and gets worse as the speed increases. It does not get worse in turns. And it is very consistent- not clunking or clicking, just a steady sounds almost like strong wind over an object. I replaced the wheel bearings in both front wheel assemblies about a year and a half ago.
Prius (Gen 2) :: Whining Noise From Front End At Around 30 Mph And Increases With Speed
Over the past 2 weeks, started having a whining noise from front end. It seems to be coming from the front passenger side. The noise starts at around 30 mph and increases with speed. Very noticeable at highway speed. Sounded a bit like tire noise. I did rotate the tires, front to back, but noise persists from the front.
View 6 RepliesHonda - Cr-v :: Speed Decreases Then Increases And Cruise Disengages
I love my 2003 Honda CR-V and it works perfectly except for the cruise control. It may work for 5 miles or 200 miles, but at some point while riding along just fine the car bucks, decreases and then increases speed, and then the cruise disengages. Once this happens, it takes a long time for the cruise control to take hold again. This is an intermittent problem and almost impossible for a mechanic to figure out. I'd love to solve this mystery as I plan to keep this car for at least 300,000 miles! I'm only up to 179,000.
