Nissan - Belts - Airconditioning :: 1994 - Engine Down Significantly When At Idle?
Jul 3, 2016
My 1994 Nissan Altima is a great little car with an unknown number of miles, though my best estimate is around 150k. Every time the air conditioner compressor kicks in it drags the engine down significantly when at idle, and often causes the belt to squeal. The squeal is most notable while accelerating. My question is, since the belt is relatively new do I have a tensioner problem, a compressor problem, or something else?

For the past maybe 10 months, my car has been giving me new AC problems. The AC runs just fine when I'm driving normally or on the highway (basically without stopping for long periods of time and out of traffic). But when I stop for a long time (traffic, drive-thru, long light), my AC begins to run hot. To be more specific, the car actually begins to feel like it is running with more difficulty, as the engine starts running loudly and then I know that it is game over and it begins spitting out hot air. I generally just turn the AC off and put the windows down until I can get moving again, and then the AC is colder when I turn it back on.
Now, about 5-6 months ago I took it to my Mazda guy and he checked it out. Of course, it did not do what I wanted exactly, showing him what really happens when it sits for too long. Anyways, he said that everything seemed to be fine & both fans were working, but that the freon (r134) was low and he charged up the system and added some freon. After this, the AC was running MUCH cooler than it was before and the problem stopped.
That brings me to the last couple months; the problem has returned. This indicates to me, perhaps, that the freon has leaked out at this point, so it needs some more r134, but with dye, so that they can get a sniffer and pick the leak. Additionally, the engine is not overheating or anything of that sort, so I don't think it has to do with the radiator or coolant. I have essentially replaced almost every other part of the AC system in the car within the last 3 years. I have replaced the condenser, one of the fans, the water pump, hoses, everything you could imagine that isn't the compressor or the second fan.

The AC compressor on my 97 Quest cycles off and on way too fast when my defroster's on. I know the AC is supposed to dehumidify the incoming air - but it shouldn't be this rapid. Is there a way to control this or shut off the AC when the defroster's on ? 97 Nissan Quest..

I am experiencing significant RPM drops when the car is at idle and I start to steer. feels like the engine is almost going to stall. I looked online it says maybe the IAC valve. where is such thing on phaeton?

I have a '94 Ford E150 (6 cyl). A few weeks ago the pwr steering fluid began to leak. I couldn't readily see where it was coming from and thought no big deal I'll wait until it's more pronounced. After a week or so of topping off the fluid, I heard a pop under the hood as the serp. belt broke (sheared off actually). Not sure if it matters but at the time I was all manual power with the steering as all the fluid had leaked out.
That's when I noticed that the power steering pulley was slightly out of alignment with the others. I replaced the belt, limped home and the next day the new belt sheared off like the 1st (in ribbons wrapped around the fan). Never had this happen before but is there any way to adjust positioning of the power steering pump and pulley?Looking on the bright side, I'll definitely have a chance to get to that leak now.

I have a 2000 Nissan Xterra 3.3L, at 114,000 miles I changed all the belts two days ago these being 3 serpentine accessory belts and the timing belt with tensioner. I do believe that the engine did not move (cams & crank) while replacing timing belt and even made sure the timing marks all lined up on the cams and the crank upon installation. The belt tension on timing belt was done to Chilton Spec. as well. I did not tighten the serpentines to spec. , but just to best judgment. Between idle -to- 3000 the engine does not seem as strong especially up hill. It idles smooth, does not overheat and there is no tapping/knocking or a check engine light. I was told that that with new belts (especially the timing belt) the motor may have to wear to the belts or vice versa and there may be some power loss till all wears in together do to now tighter tolerances. I was going to relieve some tension on the serpentines to see if maybe that would make a difference in regaining power.

I recently bought a 2009 PT Cruiser which now has 38,000 miles on it. When I sit in idle, at a stop light or anywhere else, the car begins to go through a cycle where it is at about .75 RPMS (On the dial) for about 15econds, then all of a sudden I'll feel my car shake and the RPM's fall to just below .5 and then it shakes again and kicks up to 1 RPM before settling back down to .75. This cycle repeats until I move. Also, after the first "shake" the AC on my car goes out, spitting out warm air until I begin moving again. (Not good in TEXAS heat) This happens EVERY TIME the car goes through this cycle. WHAT IN THE WORLD IS THIS!!??

Whenever it rains and I have my car in drive (idling at say an stop sign or intersection), I can hear my car chirp. If I give it gas or shift it to neutral, the chirping sound goes away. When I have the AC on, the car will chirp even in neutral, but will not chirp when I give it gas. What could be wrong? Could it be a pulley?

I have a 95 neon that is running a very high Idle. When you remove your foot off the break & gas it idles around 40 mph. Iv just replaced all the breaks and its melting the new ones already. I am receiving the following check Engine Codes: 12, 25, 32, 15. I have completed the following repairs:
1) replaced all vacuum lines.2) removed EGR Valve to clean, replaced all lines. No more engine code 32, however, now I am getting engine code: 12, 23, 25, 15.3) removed intake manifold to replace the PCV Valve as well as all hoses from the oil separator.4) replaced the IAC sensor5) used ohm meter to check all wiring from IAC to computer. no issues.6) replaced the TPC sensor7) used a ohm meter to check all wiring from the TPC to the computer. No issues.8) used a ohm meter to see if the air temperature sensor was working correctly. No issues9) checked wiring from Air temperature sensor to computer, no issues.
The car continues to idle extremely high to the point it is not safe to drive. By feeling the throttle body where the IAC lets in air, it feels like its comply open. I pulled the IAC out of the throttle body while it was plugged in and ground to the engine block. When you turn the car on you can see the IAC move, but it never seems to want to shut off air supply.
It appears the computer is telling it to let more air in even though its very high idle. I replaced the computer about 5 years ago. what would cause this?! Im to the point iv put in way too much time and money already. but I don't want to buy a new car when it could just be a $50 fix.

The timing belt broke on my aveo, destroying the engine. I replaced the engine with a used one. Now I get the car back on the road and the automatic transmission won't shift from 3rd gear into 4th. Is it possible this problem was caused when the new engine was installed, or the transmission was damaged when the timing belt broke?

My 1994 volvo 240 stalls at idle when the engine is warm. It's happening more frequently as the weather gets colder, I'm not sure if that's a coincidence. The car is an automatic and I'm wondering if it could be something as simple as low transmission fluid.

My Tacoma makes very loud roaring and whistling noises mostly when I am idle and the brake is engaged while the clutch is depressed. Sometimes, she'll rear and balk continuously --- even more loudly --- depending on the outside temperature and her level of activity. I need to get her fixed, but live in the New York City area and am a broke graduate student terrified of getting ripped off. Do you think it's just belts? My transmission (sometimes I can feel the noise in my gear shifter)?

I have a 2005 Chrysler Sebring. In December the timing belt failed while I was driving down the road. I had the dealership I purchased the car from replace the timing belt as well as the water pump while they were at it. Ever since I have had and issue with it vibrating at idle. At first it was making a whining noise as well. I took it back and they told me that they had installed the belt too tight. Afterwards I still had an idle issue although the vibration was a little different. I also could distinctly hear the belt hitting the casing a few times.
I took it back again and they stated that the belt had been put on too loose. So now they have adjusted the belt again and it I am no longer having the whining or belt hitting the casing. But I still have an idle issue. It has changed again and is kind of a pulsing vibration. I can feel it in the brake pedal when I am at stops. I seem to hear the pulsing while driving as well but this may be from my new tires as well.
During this whole readjustment process they have not mentioned actually checking the timing. Just the belt tension itself. When I first reported the idle issue after they put the timing belt and water pump on they told me that it could not be related to timing and that it had to be an ignition issue. But I asked a work associate who used to work as a mechanic and he stated that it would be a timing issue.
I am going to contact the dealership and ask them to check the timing belt again. I never had this idle issue before the new timing belt.

I've got my sister's 1995 Dodge Neon with the 2.0L SOHC. While driving it recently I heard a horrible squeaking noise then a ZZZZZZzzzzzz sound. I immediately pulled over. The check engine light came on, and I shut the car off. Coolant was all over the place leading me to believe the water pump failed. I had it towed to my house, and now I will have it towed to the shop to get fixed. I would like to have them repair the timing belt and water pump. However, I am afraid that the valves were beaten to a pulp and now I will need a new engine. I was only going 35 mph when it happened. What are the odds that my valves were smashed up, and is there anything I can do to check them before I pay for a timing belt/water pump repair?

I brought my 2004 VW Touareg V6(83k miles) to the dealer for a recall on the ignition call and much to my surprise, was presented with a diagnosis of a $6,000 problem! The dealer told me that the computer read some codes which say that the timing chain is stretched and needs to be replaced. They said it will take 4-5 days and should be done asap so it doesn't "go out", because if it does, it's an even more expensive problem. I took the car to another VW repair shop and they asked me if I heard any noised when I start it cold (like pebbles in a bucket). I have not had any problems like that at all, so they said I shouldn't worry until I start getting symptoms. They also said there is no recommended point (like 90,000 miles) when VW recommends the change, so it really shouldn't be a common problem. I want to do the right thing, but I don't want to rush into an expensive repair if it isn't necessary.

The timing chain on my 94 Nissan Sentra XE 1.6L has jumped. The car will not start and when you do try and start it just lopes and then sounds like it wants to start and goes back to loping. BTW, it has 249K on it. I have removed the front cam shaft cover. The chain is intact and looks good, but can be depressed with the finger. Upon closer inspection the chain has cut a very noticeable groove into the tensioner. There is also a noticeable groove in the upper chain guide. The question here is, can I just replace the tensioner and the guides (there are two of them), without changing out the chain. One other question I have is there a possibility that I could have damaged a valve after trying to trying to start the car with the jumped chain. Someone told my that this possible, but I have also read on the NIssan Forums that damaging/bending a valve would occur only if the chain had actually broke and I tried to start it or manually (by hand) advancing the crankshaft will attempt to get to TDC?

My Nissan Pathfinder (1994) makes a "clunk" sound when I go around tight corners, usually only one "clunk" per turn.
The sound occurs on tight turns at low speed (e.g. on a round-a-bout: [URL] ....) as the weight of the car shifts and leans away from the turn.
The sound seems to come from the front end, near the driver's side wheel.
My mechanic couldn't work out what was wrong. He removed, greased and reassembled the upper driver's side ball joint and then gave up.

i have a 1994 nissan quest 3.0 v6 and when i put it in reverse or drive it will slip into neutral if i am stopped. Also the front motor mount needs to be replaced, which I will do soon. Are these problems related, if not how do i fix the shifter/linkage problem? When driving the vehicle upshifts and downshifts perfectly.

My 1994 Nissan Pathfinder will intermittently not start. When I get in the car and turn the ignition, the dash board lights will light up as usual, I can hear the starter solenoid click, but then nothing will happen. The power windows, stereo, headlights and air-conditioning will all work but the motor will not even churn. All I hear is the click. If I get a jump the car will start right up.
This has been going on for over a year. At first it would only happen every few months and I thought that by just disconnecting the positive from the battery and putting it back then it would start. It appeared to be doing so. When it started happening more frequently, I took it my mechanic and each time he would fuss with some wires charge me 20 bucks or not charge me at all and I would be on my way. It would be good for a week or so then once again not starting for me.
After the three times of my regular mechanic not fixing the problem and saying it was fixed I took it to a different mechanic. This man said it was my starter even though it will start with a breeze if you jump it. I went ahead and had him replace it. My car started a few more times but the next day the problem was back. After having gone to two mechanics and them misdiagnosing and me paying for service I didn't need, I borrowed a volt meter and the battery test at 11.5 volts. Some buddies said, that perhaps my battery being 14 years old was putting out enough power to power the cars electronics but not enough to turn the starter over. So I bought a brand new battery. I got four starts off of it before I experienced the problem again.
Another friend thought it might be the alternator not fully charging the battery. I believe we tested it at 12 volts but he said it should be more. Anyway, he and I pulled the alternator took it to be tested and it's fine. While we were removing it though we discovered the belt on the alternator was a little loose so maybe it wasn't charging fully. Anyway, we put it all back together and the car started five or six times, while my more knowledgeable buddy was with me. The next day of course, no start.
I probably did a bunch of stuff I didn't have to do in trying to diagnose this problem but at least I learned a lot more about my car. Anyway, ye wise car sages, What do you think is wrong with my old car, which for the most part has treated me well for all these years? Ignition? a short somewhere? If it's the ignition perhaps you can explain to me why the vehicle will start with a jump.

While reinstalling my battery after working on my 94 sentra my negative battery cable melted my negative terminal.
I installed the positive first then went to do the negative and huge spark/smoke and I see my terminal melted on the one side.
What might be causing this?
