I have a 2004 Trailblazer LS with the 4.2L I6 and this problem just recently started and I found this video on youtube of someone having the exact same problem. [URL] ....
This noise is only there in reverse and drive. If you put it in park or neutral it goes away. Also goes away if you give it some throttle while in gear.
2012 Trailblazer 4x4. Got up this morning to go to work, no reverse gear. I pushed it out & drove to work (15 miles). Got to work & reverse works fine now. Drove home & parked. An hour later I go out & again, no reverse. What's going on?
View 14 RepliesThe ac condenser unit will click every 7 seconds followed by a 3 to 400 rpm surge for 5 seconds or so, drop rpm then repeat. Belt looks fine, no slipping, new plugs a month ago, newish air and gas filter, does it in neutral or drive, read many ideas from low or high freon, iac, throttle body cleaning, o2 sensor? no codes thrown. Maybe coincidental but was discussing o2 upstream sensor recently on this board. The car experiences the same symptoms while driving.

When I got the truck I noticed it would slam hard into reverse. Ever since it is taking longer to engage reverse gear and now I have to rev it to 1000 rpms for it to engage with a hard SLAM.
I also noticed that if I do a fast take off, there is a knocking sound coming from drive shaft/differential area (like knock knock knock knock knock then goes away). Then a slight vibration ending at around 30 kph (~20 MPH). There is also some oil leaking from the transmission. I added some mercon sp yesterday - it was a bit low.
My guess for the knocking and vibration is the center support bearings and U-joints. Transmission??? One thing I know I am going to be banging away at that shaft but the transmission problem really scares me.
Recently had my brakes/rotors replaced on my 2008 chevy trailblazer. the problem is when slowing down to almost stopping the brakes sound like when you stop on ice and the ABS applies..The vehicle stops..but concerned what that feeling and noise is..After applying the gas it sounds like something is stuck? Occasionally my traction control light goes on?
View 9 Replies2004 Trailblazer 6cy. 2WD - has been experiencing a very rough idle, engine shudders - no matter how long it's been warmed up. Wants to stall off red lights and at very low speeds. Not throwing any lights yet - but the speedo is out ( a cam shift typical problem for this car) so I don't trust the console for lights. Worse when the heat or air is on. Rides fine with more gas/higher speeds. Definitely worse in colder temps but continues even after 40-50 mins of driving. I've heard a number of things, but can't afford to fix them all. I've heard plugs, dirty throttle camshaft, sensors, cam actuator solenoid, etc. All seem to have people who said it fixed and didn't fix the issue. Worried I'm going to stall pulling off a stop and rear end someone any day now. Where do I start!?

I have owned car for 2 months.
Last few weeks the engine sounds louder at idle and there some vibration. The passenger side wiper arm vibrates due to engine vibration.
'02 V6 30v with 73k.. engine noise sounds like rattle consistent with idle sounds like its coming from rear section of motor. i did search came up with a few probabilities but no resolutions just wondering if possible it could be oil pump because if i add oil then start up the noise disappears for a few mins then comes back, a few guys mentioned it could be camshaft tensioner.

View 6 RepliesI have an 03 Camry 2.4 XLE that making a strange engine noise. At idle speed it almost sounds like a diesel engine clacking away. On cursory inspection it sounds like its coming from the intake manifold area. The noise in not effecting performance as the car has lots of power and the engine is not running rough or missing. What this noise could be?
View 11 RepliesMy 02 Ford Focus makes a racket in 5th gear. The engine sounds like it's ready for takeoff. The other gears are quiet but when I pick up speed, the noise is a steady & relentless hum.
View 7 RepliesMy 2005 gti 1.8t started sounding weird a few days ago, it has a really deeper tone to it, sounds like a truck or a diesel. I can also smell gas in the engine bay, car seems like it runs fine just sounds really funky. Sound gets louder as I accelerate.
Here what it t sounds like right now. Sound is coming from top of the motor or behind it near downpipe, not beneath the car from exhaust.

I just bought the car.(2 months) This is all I've done to it.
-Changed the oil.. Euro spec Castrol Edge
-Changed the Plugs and Put the red R8 coil packs
-Changed the Diverter Valve
-Changed Air Filter
Its 2012 with 47,000 miles. I had the dealer tell me its just the fuel injectors and not to worry. I've seen and heard multiple GTI's and this is My 3rd 2.0t and none sounded like this. I'm new to the GTI but have driven nothing but VW since the state gave me a license in 1997
Video of the clicking. It sounds like a Diesel : [URL] ....
I have a 2009 Scion xD and when I am idling in D or P, my car sounds like a diesel engine. It makes this propeller kind of sound on the driver side and it is worse when I am stopped or idling, but does not go away when I am driving. It has about 76,000 miles and I moved from AZ to CA, not that I think that makes much of a difference, but the high heat in AZ can cause problems for cars. The heater core went out in the fall of last year and I just had all 4 struts replaced. I really don’t want to have to spend too much more on the car to be honest and hope this is just a simple issue.
View 1 RepliesWe bought a 09 RX 350 that is a CPO, currently has 75 K on it. When the engine is first started it rattles like crazy and sounds like a diesel while the motor is at idle Once the car warms up it sounds fine.. The dealer tells me this is normal. Last oil change switched to full synthetic and it still rattles at start up.
View 2 RepliesI have a 2004 G35 that has not given me many mechanical problems. However, before my last oil change, I noticed noise from my engine which I wasnt used to. After 2 days I checked the dipstick and there was almost no oil on it which greatly worried me. I put in two 10W30 bottles and got a normal oil change the next day. Its been a week now and I still hear this noise when I start my car and its idling (cant hear it while driving cuz of the normal engine/road noise). It almost sounds like a noise I would hear from my dad old 70s diesel benz's, just not as loud.
Its def mechanical but I can't figure out what it is or where exactly its coming from. Its been 10 days now since the noise first started and it doesn't seem to be going away. I just checked engine oil levels now and they are near max. When I open up the hood, I don't hear the noise ( over the normal engine/belt noise), but its very apparent once inside the car with the doors closed and windows up. I am worried my car might end up and die on me all of a sudden while on the freeway or if my transmission is going to go bad.
2000 Windstar 3.8L sounds like a diesel engine (exactly like and old diesel) when it warms up. My girlfriend noticed the problem and checked oil and it was low, she added, and then when she started it the next day, sound was gone. While she was driving it came back and would stall out. When she got it home I checked and the coolant overflow was empty, I added water and it poured out on the front (passenger) side of the engine. I immediately assumed head gasket.
Once it cooled I started pulling the stuff out. Down to the head on the Right hand bank (front of car). There is oil in the coolant, but no coolant in oil, (or very very little). Found the coolant is leaking from water pump itself it looks like. where the lower rad hose goes into pipe for water pump. or on the flange seal for water pump. It is so tough to actually see where. It also looks like the intake gaskets were bad because of the dirty oily wet condition under the intake manifold.
The car only makes the noise when warm, when it is cold it runs just fine. Would just the water pump being bad and leaking coolant cause this problem, is it a bad head gasket, something else? If it is the head gasket, I cannot get the head bolts to break free. I didn't have a 15mm 1/2 drive, so used a 3/8 drive and the 1/2-3/8 adapter spun right off.
I have a 2004 Camry XLE V6 with about 70k with a CEL P0171 that came on yesterday. Looks like that code is for a lean condition. Could it be a bad O2 sensor or is that a different code and what should I look for to fix this code?
Also, I'm not sure if this is related but for the past few months my engine has sounded different. When I first start it up and at low RPM like 2,000 and under the engine sounds like a go kart, not necessarily louder it's just a different lower tone that it never used to have. It has sounded like this for 6 months but the light just came on yesterday.
I have a 2016 f350 super duty with 6.7L engine, at random times engine sounds like it has a rod knock, give more fuel, it goes away, driving at 40 to 55 mph the whole vehicle shakes all at different times and different days vehicle has under 6500 miles want to now anything before going back to dealer..

1st issue....When accelerating the fan comes on and it sounds like a jet engine taking off. Let off and it goes away! It acts like it does when you're towing something and put it under a load but you're not towing anything?
2nd issue...when towing a month ago hit a hill and totally lost power it was down to 25-30 miles an hour with it floored. Tranny gauge got up to about 3/4 but never any further. Let off pedal to try and get new gear and did not work, was like it was in a limp mode but never threw the wrench up. Finally got to top of hill and she cruised down other side just fine. No loss of power tranny back to normal. Then towed over weekend on flat land and tranny gauge went almost to overheat. Didn't seem to have power issue.
Since 1st tow issue it had 8 new injectors installed but hasn't seemed to change much. Fan issue was there before injectors and new injectors only, worked only with the cutting out it would do when cold and when driving in overdrive. Computer issue? Relays?
So whenever I brake while reversing (and rarely while moving forwards) I hear this odd grinding noise coming from the front left wheel and can feel it through the brake. Im not a petrol head but I decided to replace a wheel bearing hub myself recently to save money. I am pretty sure I reconnected the anti lock brakes correctly though I doubt it's that. My brakes are good.
