Chevrolet - Blazer :: 2000 - Volt Gauge Fluctuating
I recently had some issues getting my 2000 Blazer LS started. It would act as though the battery was dying. But if I let it set a few moments, it would start right up. Then a couple days later, I needed a jump start to get it going. I took it to my local Auto Zone to have the alternator tested because the battery was only 3 years old. (It was a 5 year battery.)
They determined that it was the battery. So I went to Walmart and bought a 700 CCA battery. And today the gauge is fluctuating again.... Considering it is cold and snowing here, heat, wipers, and rear defrost tend to be essential. But if I try to run all of them, the gauge dumps. And causes everything to bog down. I do not have any aftermarket electronics installed in the truck. And until last Thursday, this was not an issue.

I just purchased a b5 99 1.8t. The tubing from the intake manifold to the dv was cut by accident (long story, dont ask).I replaced the dv and tubing .I want to check if the psi is correct. I dont have a boost gauge.
What are the ways to check it besides a boost gauge? I think the correct psi is around 6-8 ?
Chevrolet - Lumina :: 1999 - AC Compressor Clicked On But Cooling Fans Not Running
99 lumina. Ac was not working. I added a few oz's and the compressor clicked on but cooling fans were not running. After 10 min of idling the fans did come on but went off after 1-2 minutes. It seemed like they were responding to coolant temp more than ac pressure. Do the fans run when the hi pressure rises to a certain point where the computer will turn on fans?

OK... I know next to nothing about cars. I have a '99 Chevy Lumina I just bought in February. It has been one problem after another. The water pump has been changed and I just got my car back on Monday because there was a leak on the timing chain cover. Now, the car is smoking on the passenger side. Its not a light smoke, but its not heavy yet. I noticed it on the way to work this morning. I opened the hood, it is coming from the left side (looking at it, so the passenger side) of the engine maybe kinda underneath it. I dunno what to do, but I'm ready to push that thing into a lake.

View 13 RepliesBuick - Regal :: 1998 - Weird AC Pressure Readings On The Gauge
1998 Buick Regal has strange readings on the gauges. 80-85 degree ambient air temp, low pressure is 60, high is 125. I have 100 lbs of static pressure in the system with the engine off. I am getting some cool air, but I would expect that the high side pressure is not high enough to cool well. Do I have a plugged orifice tube? Is my compressor not compressing enough? Or is my refrigerant low and causing the problems somehow?
View 13 RepliesMercury - Grandmarquis :: 2000 - Weird Temperature Gauge Readings
2000 mercury grand marquis drives fine and then suddenly temp gauge in dash shoots straight up and then comes straight back down. This lasts for about 3 seconds. The engine will hesitate during these 3 seconds. Then it drives around fine for awhile (an hour or so) and then suddenly shoots back up again. I have replaced the coolant temp sensor and thermostat and coolant level is normal. There is no coolant in my oil or any signs of a leak. My alternator was charging a bit high the other day at 15.4 and I am not sure if that would cause the temp gauge to act up.
View 16 RepliesC/K :: Fluctuating Temperatures On The Gauge - Replaced Water Pump
My brother has a '92 K1500 5.7L in which he had a leaking water pump. He replaced it with an Autozone unit. After replacing the pump, he now states he is experiencing fluctuating temperatures on the gauge. He has little heat at the heater, even after letting the truck idle and after driving it. This was not a problem prior to replacing the water pump. He has put approximately 200 miles on since the replacement and it has been about 2 weeks since he replaced it. He believes he has all the air out of the system, as he has checked the overflow container and radiator several times and the coolant level has not gone down.
This now "suddenly" appears after the pump replacement, we are thinking it is not the temperature gauge sensor or bad thermostat. We are thinking possibly still air in the system or water pump cavitation.
Passat (B5) :: Coolant Gauge Reading Fluctuating When Driving
Have a problem with the coolant gauge on their Passat? The temperature gauge on my 02 Passat sometimes reads normal (190) when I am driving and then all of a sudden it will drop back to 90. My first guess was the sending unit, but the dealer says it might be the gauge cluster too. I would think that if it was the gauge cluster the other gauges would act up too. ?
View 7 RepliesFord - Explorer :: Oil Gauge Starting Fluctuating Rapidly
So today we were driving back home and the oil gauge start fluctuating rapidly. However it would only fluctuate when the engine speed was slow, like when you are at an idle in gear. Once I gave it some throttle the needle came back to normal. Also while making a turn the needle stayed steady as well, which made me think that it isn't a low level situation,(plus I did verify the oil level once I came to a stop).
I keep reading about oil pressure sending units going bad. I just so happen to an extra aftermarket sending unit and gauge from summit racing laying around, so I'll hook that up tomorrow and see about what the pressure actually is at idle. I hope that it is just a small problem. Whats the pressure supposed to be for the 4.0 OHV at idle anyway.
Elantra MD (2010-15) :: 2012 GLS - Temp Gauge Fluctuating And Overflow Was Really Low
My son recently bought a 2012 GLS. The temp gauge was fluctuating and I noticed the overflow was really low. I added coolant and warmed the car up with no change. After it cooled a little, I cracked the radiator cap and heard bubbling air. Upon complete removal of the cap, I saw no fluid, however, the cap is above the radiator where the hoses connect. I added coolant directly to this opening until I could see it. Closed everything up and warmed up the car. Temp gauge is now steady 1 mark below half way. The question is, did I add enough coolant? and should I see coolant inside the radiator cap when the vehicle is cold?

View 4 RepliesJeep - Cherokee :: Low / Fluctuating Oil Pressure Gauge And Spiking Temps At Idle
I have a 1998 Jeep Cherokee L6 4.0 Liter automatic with 223,000 miles.
The oil pressure usually runs around 1/8-1/4 when driving around town and now I am getting temperature spikes. I had the coolant and water pump replaced last fall when I was having similar idling issues then. My coolant isn't a perfect green color--it is a little bit grey, but it is full. I cleaned the entire throttle body last January, cleaned the IAC today, and redid the NSS this week (not that this probably matters, just being thorough in my explanation).
It seems to happen worst on hot days (of course) when idling in traffic for a few minutes and makes the air conditioned air run warmer than it should.
Is this a busted radiator? The mechanic said I did not have a leak when I had him check last week.
Santa Fe (CM - 2007-12) :: Check Engine Light Comes On - Fuel Gauge Fluctuating
I have an 08 Hyundai Santa Fe. Check engine light comes on, fuel gauge goes from empty to full, to half, to 1/4, just all over the place. Even ran out of gas a few times on the side of the road not knowing how much fuel I have.
What exactly causes this problem? I've heard "fuel sender" I've heard "fuel pressure sensor" etc. All are different parts. Need to get this repaired asap.

View 7 RepliesSilverado :: 2010 LTZ Rough Idle / Headlight Flicker - RPM Gauge Fluctuating During Rattle
So I recently bought a 2010 Chevy Silverado LTZ with 31,000 miles (5.3l engine). After having the truck a few days, I have noticed a couple of problems ...
1) I have noticed there is a rough idle in the passenger seat while the truck is in drive. Once the truck is started and driven about 5 minutes, once you come to a complete stop in drive (ex. stop light) a rough idle over takes the truck. You can feel this idle a lot more in the passenger seat than in the driver seat. The RPM gauge also fluctuates during the rattle.
2) At night my the headlights flicker randomly, on and off very quickly.
3) In the morning when I start the truck and drive it a bit, I hear a rattle which sounds like it is coming from the front right of the truck. Bumps do not trigger this rattle, which usually only lasts a couple seconds. I usually hear the rattle between 1,000 and 1,200 rpms.
I have taken the truck into the shop 2 times to get these items fixed, and they said they cannot feel a rough idle.
Impala - Chevrolet :: Coolant Temp Fluctuating / Going From 200 Up To 240 Sometimes 260 Degrees
I have a 2002 Chevy Impala with the 3.4L engine. The car has 180K+ miles on the original engine. The coolant temperature started fluctuating recently. Going from 200 degrees up to 240 sometimes 260 degrees.
I recently had the check engine light on with the P0420 code which indicates a bad catalytic converter, I had that replaced and I was hoping that maybe the lack of exhaust flow through the converter was causing the overheating. It is still fluctuating however after the converter replacement.
The coolant temperature seems to go up when the car is idling but when moving it starts to go back down to normal. I had the cooling fan assembly replaced last year after one of the fans failed. These are less than a year old and are both operating as expected.
A little history on the engine. It originally had that crappy DexCool in it that then ate away at the cheap plastic head gasket causing oil to leak into the coolant system. This caused the coolant to turn into 'mud' within the radiator and eventually the head gasket failed completely and I had to have that replaced along with putting in ethylene glycol to replace the DexCool. Now when the coolant system was flushed, I am not completely sure that all that 'mud' was flushed out of the radiator. So the radiator may not be operating at full capacity. In fact, driving through the mountains this summer going up inclines, the car would tend to start overheating.
So thoughts on what might be the issue, radiator, thermostat, sensor, water pump, something else? I'm pretty sure it's not the sensor because sensors don't fail in this manner (they fail either high or low). I'm leaning toward the radiator because once I get some air flow across it, the coolant temp gets back to normal.
Also, the A/C is sometimes working great and blowing really cold and other times it is just slightly cold.
