Pump - Chevrolet - Heating - Lumina :: Short Rattle When Driving At Highway Speed
Oct 23, 2011
'98 Chevy Lumina. Driving at Highway speed, I hear a short rattle. Makes me think of linkages vibrating, from the passenger area. Few minutes later I hear it again. Few minutes later I look down to see me thermostat at 240+. I watch it redline, hold for a few minutes, then the rattle again and my temp goes down to 160 or so. All of this happens at 60 mph, in 45 degree weather.
Rinse, repeat about every 10-15 minutes. I notice that while the engine temp is climbing, I have no hot air from the vents and after the rattle and temp drop I do have hot air. Check the block when I get home and I see the familiar green puddles. So is this: Water pump, the apparent source of the leaks, heater core causing back pressure to leak at the hose, or the ever dreaded head gasket?

I have a 2009 Pontiac Vibe GT with about 255,000 miles. Over the last several months I've noticed a rattling noise coming from the right front quadrant of the car when driving at highway speeds (60 MPH and up). I also notice that it seems to diminish and/or go away entirely when I drive in the rain. I took it to the dealer and they said I need a new right front wheel bearing/hub.

1991 Chevy 1500 pickup truck. The heater is ALWAYS on, no matter what I do. I suspect that some sort of mechanical controller or vent shut off device/air mixer is malfunctioning because I don't think the heat is actually coming from the heater core, I think it's just engine heat.
I pulled the fuse on the heater which turned off the blower and controls, but the heat is still coming out the vents, especially at highway speeds. So this leads me to believe that exterior air is pulling engine heat into the cab.
I don't know how I would even begin to fix this. I need a starting point. Where would I look for the vent or flap or whatever that mixes the cool air with the hot air? The AC hasn't worked since I bought the truck about 18 months ago.

I bought the car( like six months ago) there has always been a loud humming noise from the fuel pump ( I'm pretty sure it is the fuel pump anyways) not the normal whirring noise the fuel pump makes but a hum you can hear about ten feet away. Had no issues till just lately when the afternoons are well into a hundred degrees. That is when my car starts giving me issues. After one of these hot days on my ride home from work, I had just come off the highway and stopped at a stop light when I felt the engine bogging out, the engine stalled and I had to push it to the side of the road.
Its worth mentioning that this humming noise is much louder in the heat than the cool morning then when I turned the key to hear the fuel pump(auto fuel inject) it was louder than it has ever been, and would keep stalling on the way home, I had at the most a quarter tank of gas (gas boy is busted/stuck I think) the fuel pump is bad? Could it be the sock? I thought I read somewhere that my girl pump uses gas to cool down, and that having the tank any less than a quarter could lead to the fuel pump overheating????

I have a '99 Chevy Lumina 3100 V6 with 54k miles. There is a loud, high-pitch buzzy whine that changes pitch with engine RPM/transmission speed. The whining noise is only evident while the car is accelerating (forward or reverse), and above 5 mph. I removed the serpentine belt and drove it briefly (500 feet) - the noise is still there without the belt. I figure it's safe to assume it's not the power steering pump, alternator, H20 pump, idler or belt tensioner. The transmission has had regular service, and shifts smoothly in all gears (fluid is clean and level is full). There is only a slight raspy "scraping" noise in park or neutral, which becomes almost undetectable when shifting to drive or reverse with the brake still applied.

I have a 1991 Chevy Lumina and I believe this wire is the root of my problems. I
wasn't the one who unplugged it but it seems it was unplugged as an easy way to get around a problem. When unplugged the car runs but the performance is off, It doesn't feel like it has the same power as it does when it's plugged in and it also sounds different when in idle. When the wire is plugged in the car stalls while driving at random intervals between 1 and 10 minutes and needs to be jumped to start it back up. I will attach pictures of the wire and its location within the surrounding area.

I have a 2011 corolla S with 32.5k on it, so my 3yr/36k warranty is running up in a few months. my car from day one (that I had it, at 17k)has had an annoying rattle in the headliner ahead of the sunroof, near the overhead lights. If I press up, even slightly on the lip of the headliner around the front of the sunroof cutout, it goes away. Dealer thinks its normal and says repairs wouldn't be covered under warranty.
The second is a new one, when I go over a bump in the road at highway speeds, there is a squeak coming from the center of the dashboard, at first I thought it was a strut, but after driving back and forth on the same stretch of road for half an hour, I found it to be coming from somewhere behind the radio. Dealer says, squeaks will happen as a car ages.
Do I need to take it to a new dealer (about an hour away) or can I fix this myself?

I have a 2005 Malibu. After two alignments, a front wheel alignment by an independent shop and a "four wheel" alignment by the dealer, my car still pulls to the left at highway speeds. What else could be the cause of this? Bought the car with 22,000 miles and now have 80,000 plus. No accidents; don't understand what is wrong.

I have a problem with the front rotors on my '01 Impala warping. The pulsing is really bad when decelerating from highway speed. They will last maybe a month after installing before they start to warp again. I purchase my parts at the local NAPA store. Is there something I could be doing wrong during installation or it bad parts (cheap material)?. Could it be an issue with other front end components?. The car has 173,000 miles on it.

I have a 4l60e transmission that was rebuilt less than 500 miles ago, I was driving on the highway when all gears were lost. There is clicking in the front part of transmission. Can I just replace pump? Fluid is clean no pieces in pan, are cluthes still good?

My husband has a 2009 Chevy Aveo, he's had several issues lately, split radiator hoses, an oil pan issue and now he says it's decelerating when he's driving on the highway, the engine doesn't rev when he presses the gas pedal, we can't afford a new car but he's afraid to drive an iffy car through the winter on a somewhat long commute?

I have a 1999 Chevy Blazer LS 4WD 95K miles that had an incident in 2008 where the oil pressure dropped to zero while driving down the highway. I immediately pulled over and had the vehicle towed to a dealership. They pulled the oil pan off and let me know the lower part of the motor was "toast." (crankshaft had turned blue due to heat from no oil.) Mysteriously it has oil pressure now, why that is. It started last time I tried about 4 years ago.
I dearly loved this vehicle. It was first car I bought and paid for myself and I planned on repairing it one day. It's been sitting in My garage for the last 8 years. Recently, my daily driver died and I was faced with repairing the Blazer or buying a new vehicle. Since I don't know how well the Blazer has fared sitting in the garage all these years, I decided repair wasn't worth it at this time for a vehicle I needed to be dependable and I just bought a new vehicle.
So here's the thing. I kept the Blazer really clean. Washed it all the time, no damage, Regular oil changes, the works. It still smells like a new car inside. I really don't want to see it get crushed and I'd like to see it go to a good home. It might need more work than a new motor since it's been sitting so long, but I can't imagine it would be more than someone mechanically inclined could handle. I'd get a new engine, but I don't have the cash and I need the garage space.

Okay....I have an 01 blazer 6 cylinder 4.3. For a while it was missing fairly bad until I had the distributor replaced and the problem went away for about 2 months. Now it seems to have the same problem again so I am wondering if that wasn't the real problem. Here is what is going on. The tac needle bounces and it feels like the engine is misfiring. When I am driving on the highway sometimes the CEL starts flashing. Sometimes it stops and sometimes it doesn't. Plus now it feels like when it changes gears it's lurching. It only does that sometimes. The odd part is there seems to be no distinguishable pattern to the lurching. I think the misfire could be just the timing needs to be adjusted.

My 2009 sonata started having issues with slight up and down accelerations while cruising and the check engine light would come on Then during start up the engine would accelerate up and down about 1500 rpms. I have taken it to two dealers neither could find anything wrong and said their was no record of an event on the computer. Now the car is stalling while driving, once at highway speed. It has happened three time this week. After coming to a stop, I wait a few minutes and the car starts up like their is nothing wrong. The engine light comes on for a while.

So I was driving on the HWY in 6th gear cruising at about 60, and I go to speed up and when my RPMS hit about 3k or over it feels like I am pressing in the clutch, like my RPMS are going up but I am hardly gaining any speed.

My truck is a 1997 nissan pickup with. 254,000 miles. Check engine light come on. Only when I am at highway speed. As long as I am in city traffic, nothing I have a code scanner code (PO302) number 2 cylinder misfiring. I change spark plugs and wires and dist cap. But check engine light came back on. I put in shop they claim that they can't find nothing wrong. I guess I need to find a new mechanic.

I have an 04 Elantra GT and have been noticing a jerkiness when driving at a constant speed on the highway. I haven't noticed it around town or while accelerating. I also have noticed that when I disengage the clutch on the highway, the engine sometimes doesn't respond right away, or it even may surge. This has happened when exiting the highway when I disengage the clutch. The engine will slow, then speed up close to 3000 rpms.
I also had a check engine light come on and couple months ago. The code indicated that the upstream O2 sensor was bad. I took it out and cleaned it, but didn't replace it. Is this a likely culprit for this set of symptoms? If so, how can I test the sensor to be sure? I heard that I could disconnect it and run the car and see if the surging lessens, but wasn't sure if that was a good thing to do.

I have a '99 Chevy 2500 diesel truck. After driving it at highway speeds for more than 20 minutes and turning it off, it won't restart. The problem seems to be in the battery cable and is definitely heat-related. In cold weather or after a fairly short drive, all it takes is popping the hood to cool off the engine compartment, and waiting. If the engine and/or the weather is too hot, that can take an hour. Then it starts just fine. I've cleaned the terminals and made sure the connections are tight. Two mechanics have looked at it and were stumped.

My father passed down his 1973 Chevy C-10 pickup truck to me and my family. It's been our 'runner' truck for many years going to the mountains for wood, lumber from the store, garbage and yard debris...etc. Unfortunately, it recently has been starting and warming up just fine, but once it's running as I'm driving away from stops or even holding speed on the highway the power 'fades' from the engine and it lugs like it is in gear, but flooded and lurches as the engine seems to 'catch up'. I have replaced the carb(holly quadrajet), fuel pump, fuel filters, battery, fuel lines, throttle cable, distributor cap (ceramic piece too), alternator and more...we still can't get it figured out. NOW the truck won't start or turn over - have we reached the end of it's life no matter what we do? What is left to replace? I don't think we can afford much more $ to fix it. We also found that somehow water was in the gas tank, which we think was from a kid in the neighborhood messing around. Could that have made a permanent issue?

Ok, so I was driving normal highway speeds and all of a sudden, I realize a major drop in power. I pull over and restart it and it changes nothing. Now when I floor it, it takes 20-30 seconds to get to 90K.
I checked the air filter... Nothing. Used a code reader... Nothing. Then I decided to pressure test the cylinders... Nothing, except now the check engine light is on.
The Ol Dub is still drivable, but it is extremely slow and rough at idle. I am thinking it might be a MAF or fuel filter.
