I recently started to notice what sounds like a vacuum cleaner coming from the engine at start up, usually in the morning. The sound continues for about a minute or less then goes away. Haven't noticed it after repeated starts during the course of the day. Car runs fine, no CEL's.
View 4 RepliesRecently my car has been doing some weird things. After driving it for about an hour, I get a sound from the engine compartment that sounds like a vacuum cleaner. It's fairly loud, but it's mostly just noticeable from the outside. The car continues to run, but if I turn it off, it doesn't restart (does not even crank). Last night I was driving at about 55 MPH and all the electronics went off and then came back on. In other words, the radio restarted and all the lights turned off and back on. The headlights turned off, but they did not come back on no matter what.
View 2 RepliesI have no vacuum coming from the engine to the IWE solenoid. This is making my hubs stay locked all the time. where this line from comes from and how to fix this. Which line is the line from the engine, the one with the T in it or the other one?

I have an exhaust leak that has gotten worse and is quite loud now. I have been under the car and a mechanic just checked what he could without a lift and didn't find any leaks. Yesterday, I had it up on ramps and looked under and think the sound is coming from where a heat shield is. When I'm in the car the noise sounds like it's slightly in front of me.
View 3 RepliesOk just so I know what the dealer may do to fix it....I have a weird hissing sound coming from the driver side like a vacuum hose is off or something...but when I apply the brakes it goes away...I let go and it comes back...when I shut the car off as well it stays hissing until I hit the brakes again or it just quiets down... What this may be?
View 1 RepliesI noticed my sound a few weeks ago but wasn't as loud as the videos I've seen. Didn't really bother me. I did notice today that the sound was a lot louder . The only thing that has changed is i had my oil changed over the weekend with mobil 1 5w-30 fully synthetic. Now I don't know if that could factor into the sound getting louder.
I am really hoping its just a cat and i can replace my headers and everything is good. i just got the car with 19k miles on it and do not have a warranty.
I have been worrying about "engine noises" for years and at this point if its something i can't fix without dumping thousands of dollars into it, then so be it. I am just going to enjoy the car too the fullest. Plus, once i get full exhaust, it will work with canceling out the ticking sound.
I have a 2003 VW Jetta GLS 5 sp. Manual with the 2.0 Naturally aspirated 4 cyl engine. The car has approximately 147,000 miles. My MIL light has been on for some time now. I recently got my local mechanic to run diagnostics on it and he reported two error codes (411 and 420). To my understanding, 420 is due to the imminent failure of a catalytic converter, an issue which I have addressed by replacing Plugs, wires, distributor, and cat.
My real question is, I would like to know if a mysterious Vacuuming sound that comes from my car whenever I start it cold in the morning and persists for about 25 seconds, and then comes on and off intermittently, is related to the 411 code. My local mechanic told me that there is some kind of exhaust recirculation motor that may be going bad.
I love my VW and want to keep it running properly rather than give it up, so long as there is no serious problem that is impractical to fix.
So, I have heard a little bit about the oil pump bolt issue. However, I am still confused. Was this issue fixed for the 2008 model and what are the symptoms? I changed out my valve cover last night due to a PCV valve failure. The car is running great except there is a slight rattling sound coming from the drivers side of the engine at idle. I know I left nothing around the car that could have gotten in the motor when the valve cover was off. This issue was not happening before changing the valve cover. What could be causing this noise, or is it typical for this motor?

View 11 RepliesI've a loud squeaking sound coming from the front of the engine on cold start. This only happens when I start the engine after overnight parking . There are no squeaks when the engine is warmed up or when I start up with a warm engine.
I'm driving an 07 Camry and live in a region with hot tropical weather.

What could be the probable cause of the this and how do I rectify it?
Upon starting, my 2002 (160,000) has a rattling sound coming from the passenger-engine side. I just started noticing it and it seems to happen in the morning on its first start up. It doesn't seem to be effecting driving, but not sure if it was something to be concerned about.
View 2 RepliesOk, driving home tonight from boarding (semi hard driving) car started running and shifting weird, loss of power, weird shifts in drive. At first red light I could hear a sucking sound when the throttle was pressed,or downshift tranny in manual mode. If you put the car in neutral going down the road and stab the pedal about the third time throttle will maintain 3g rpm. Babied it home, popped the hood blipped the throttle and there's def. a huge sucking sound coming from engine bay. I lightly sprayed intake/vacuum hoses/airbox etc with starting fluid and no change in idle. cant see anything loose. WTH?
View 24 RepliesI've had this car for awhile now and it's always had this weird whining sound coming from the engine.I had the transmission serviced thinking maybe that was the sound and it wasn't. I've taken off the serpentine belt and spun all the pulleys. I can't figure it out, I'm thinking maybe timing chain but I'm not sure.
View 12 RepliesMy 04 F-150 has recently been blowing these two codes. I've replaced the coil pack already and it is still making the check engine line come off. Just put some injector cleaner in the tank last night, so that might take a while to work through. What I should be looking for?
View 8 RepliesI have a check engine light on the car and in the past it has been bad gas or a vacuum leak. Dealer says on toyota that is not possible.
View 3 RepliesI recently had a Jasper rebuilt engine installed in my Ford E150. Since than my check engine light keeps coming on and the computer is saying my cas air mix is "lean". The instaler says i need a new fuel pump.Another mechanic says it is more likely a vacuum problem.I know it's possible that the fuel pump is bad bur since this has just started since the install, I don't believe it can be the fuel pump unless it's just one hell of a coincidence.
View 6 RepliesSo this morning I started my truck to move it out of the driveway and it sounded funny almost like I was running a ship vac under the hood. I moved it and shut it off and when I shut the truck off it sounded like screeching tires. I thought it was weird but chalked it up to it being cold. When I came home I started the truck again and I got the same vacuum noise. I figured I would let it run some since it was pretty cold out. All of a sudden I heard the noise stop so I went out and all I smelled was a burning smell but the truck was idling fine and running nice and quiet like it usually does. So I shut the truck off and then it wouldn't start again. So I tried to jump it still wouldn't start would barely try to crank. I crawled under smacked the starter a few times jumped it again and it started. I left it running for 20 mins after that no noise sounded fine. Any thoughts on what this could be?
View 13 RepliesRecently I've been having some intermittent trouble starting my 2008 Chevy Equinox LS. The problem only occurs when I leave my daughter's daycare after dropping her off in the morning...so it's the second start of the day, after about a 5 minute drive. All other times the car starts fine. Here's a rundown of the symptoms:
-May 9th or 10th: I tried starting the car (at the daycare) and the engine made sort of a buzzer sound, and didn't start. Then, after a few seconds, I tried it again and it started right up.
-May 11th: I did some interstate driving (about a 1.5 hour trip each way). On the trip up, after about an hour or so, I received the following warnings: "Service Traction Control" and "Service Stabilitrack." After I turned off the car the warnings have never come back on (don't know if this is related to the starting problem, but figured I would mention it).
-May 18th: while sitting at a stoplight, the car was idling roughly - I had to really hold down the brake to prevent the car from lurching forward, and the RPMs were going between about 800 and 1500...haven't noticed any rough idling since, though.
-May 20-24 & 27-29: Again, when leaving the daycare in the morning, when I try to start the car, it sounds like a machine gun. It usually won't start the first time, but will the second time after still making that noise. Attached is a video of this. The odd thing, though, is that it hasn't done it the last two times I've left the daycare (I doubt the problem just fixed itself).
Does running a can of top end cleaner through your engine like Seafoam foul your oxygen sensors? should they be removed beforehand?
View 3 Replies1997 Chevy 2.2l 4cyl LS model. Changed fuel filter and am trying the fuel pump tomorrow. BUT if this doesn't work? I want to be ready because this is my only vehicle. Has spark, turns over but acts as if not getting gas. (Recently had new clutch installed.)
View 7 Replies.About a week ago NC got some really bad rain and in about 5 minutes the roads were under water. I had to end up driving through about a foot of water to get home, then parked the car. On my way home from work the next morning my car barely made it home, would cut out over 2k rpms and die if i didn't push the clutch in.
I sprayed some MAF cleaner on the sensor and tried that, it now will not idle when slowing down and will shut off every-time while rolling. (Also, while it is running it idles HORRIBLY and doesn't seem like it wants to pull boost efficiently)
I unplugged the maf and it does run a little better but when i pull the full 21lbs of boost then let off of the gas it dies.
Also i scanned the CEL and it says something about the MAF, i cleared it but the TC light never went off. and the CEL came back on in minutes.
