Dodge - Neon :: 2000 - RPMs Go Up But Will Drop Back Down When Speed Increases
Jun 19, 2014
I have a 2000 Neon with about 170K miles on it. with in the last 2 weeks it has been having a problem with acceleration. When i start to drive the RPMs will get up to 4 before it will start to move. Also when i am drive and need to pick up speed the RPMs will also go up to about 4 before it starts to pick up speed, but will drop back down when the speed goes up. I have found a little oil in the spark plug tubes and will be changing the seals out, and I have cleaned to MAP sensor as will. What is going on with my acceleration.

2000 neon automatic. My wife was complaining about the rpms jumping around when on the highway going about 65mph. The rpms are around 3000 and jump very slightly up and down and you can hear the engine tone change when it happens. Checked tran fluid and it was low about 3/4 of a quart and added some fluid, changed spark plugs and wires and the problem is still there. Doesn't happen all the time. She says it seems to only do this if the car has been sitting for a few hours or longer. There is an code for the downstream sensor which needs to be changed.

I drove my daughter's Dodge Neon last night and found that when I'm on the highway, the RPM goes up slightly every few seconds. I had about 30 minutes of driving until I was home so I tried to figure out if my speed had anything to do with it.
It doesn't happen when I decelerate or am at an idle. When I'm on a flat stretch of highway and using the gas pedal, the RPMs will increase. I didn't notice the feel of the engine changing, I heard the engine speed up a bit.
What kind of problem is this? The car has 109,000 miles on it.

2003 Subaru Forester with 130,000 miles. We put new tires on two months ago and when I started hearing the wah, wah, wah noise coming from the back of the car (rhythmic - increases with speed of car) I assumed on of the new tires was bad. It isn't. Also pulled the brake drums and cleaned everything there up.... What this might be?

I have a code scanner which indicated that I should change the MAP sensor. I did that, and just for fun changed the idle air control valve and throttle position sensor. Now the idle is extremely smooth in park or neutral, but once I'm in a moving gear it's up to the same shenanigans, antics and tomfoolery I described in my original post: 96 Dakota SLT idles rough & stalls. So I have a 96 Dodge Dakota SLT 3.9 4WD. Anyway, it idles relatively smoothly at about 700 RPM in drive or neutral, but if I'm in a moving gear and need to stop, the idle is extremely rough. Usually, the RPM's will drop to near 0 within about 20 seconds of coming to a stop. It will typically recover and continue with rough idling and near stalling a few times, but within a minute or two it stalls. A few additional details: it starts right up again after falling, it doesn't make any difference if I start it cold and drive immediately or drive it for an hour before coming to a stop, the same thing happens. Anything that looked suspicious to me has been changed (drivebelt, spark plugs & wires, distributor cap & rotor, pcv valve, idle air control valve, and, of course, the air freshener).

My 2000 B5 1.8t began getting the Low Oil Pressure warning light over the winter, and has gotten progressively worse. I added a mechanical oil pressure gauge and I'm seeing about 20 psi on a cold engine at idle. If I rev to ~2500 the pressure DROPS to between 5 and 10 (and triggers the STOP! light).
I tried a bottle of autoRX, but probably too late- I could only run about 200 miles before the STOP! light wouldn't allow me to get out of the driveway.
What might cause the pressure to DROP as engine speed increases? a Clogged screen or worn pump possibly? It would be nice if it was something I could correct without pulling the engine (but I'm not expecting that).

2000 Dodge Neon having issues with freeze plugs falling out. Have replaced at least four freeze plugs over the last year and a half. Is there a solution to avoid constant replacement? Neon has about 135,000 miles. There is no warning when a plug is about to fall. Research shows freeze plug issues are not isolated to the Neon and perhaps copper plugs are the answer.

2000 Dodge Neon clacking noise at low rpm after releasing gas pedal. Around the 2000 rpm range letting off the gas produces a clacking noise. I have listened to the engine with a long screwdriver at idle and revving. The noise is not always present in this condition. Although when it has come up it seams to coming from behind the engine. Does not seem to be valves, connecting rod or main bearings etc.... Only at low rpm 1200 thru 2000 rpm WHEN releasing the throttle. Clacking seams to be timed with the crankshaft as it reduces the sound as the engine reduces rpm, not at the speed of the cams. Sounds fine at idle, going through gears and at freeway rpm's.

I have a 2000 Dodge Neon with a 2001 Neon motor in it. I have just recently had problems with the car overheating. So we started diagnosing it and replaced parts that we thought were wrong. We replaced the water pump, thermostat, radiator cap, and timing belt. The problem that I am having is that the car won't take coolant out of the reservoir tank. I have bled the air out of the cooling system and it still didn't fix the problem.

I have had my car sitting for about 2 weeks and I had ah problem with my car were my nuts came off while I was driving some how when I pulled over the car was wobbling I had 2 bolts left holding the tire on. I had gotten my car towed to my house and had new prongs and bolts put on my car since then but now when I try to drive or move the car it only moves maybe 1 foot forward and maybe the same amount of feet backwards... What this problem may be I tired to turning the steering wheel while pushing it backwards but nothing works... It's like when I'm trying to move it I'm bumpin into something or I have ah block behind the tire that's keeping it from moving.

I'm looking at a dirt cheap Explorer 4.0, has been sitting for 2 years. Runs nice, with a double "knock" noise but quieter than a rod knock. Idles smooth at 600 rpm, "knock" is consistent, but increases as engine increases speed. Has 2 year old oil, and 2 year old gas. Would a tune up support it, and revitalize it, or is the engine almost dead. Still drives, didn't push it to hard. Interior is 9/10, exterior is 10/10. I have him down to 600. 4x4 works, and feels good.

99 Dodge Ram 1500 Automatic 5.2L. Whenever I come up to even a slight hill the A/C will stop blowing and the vehicle speed will drop 3-5 mph and stay until after the top of the hill and will be sluggish to regain speed and A/C will blow again once original speed is achieved. No engine light or warning lights come on. What could be causing this problem?

I'm having Dodge Neon 2000 manual transmission. Suddenly the reverse gear stopped working (others working). I got it towed to my regular mechanic (used to charge comparatively lower than other local shops) and he said one of the shifter cable is broken and other one is stretched. Need too replace them. Is it worth it? (It's an old car and recently I've been spending a lot on this).

So over the last few months I have been having more and more idling and power loss issues with my 2006 V6. When idling she intermittently will try to stall and the rpms will drop below 500 and then spike back up. A large percentage of the time I hear a loud whining sound while driving down the road and I notice that turning off the air conditioner will remove the sound at times.
***what I have done so far**
Idler Pulley
Belt tensioner
sepentine belt
cleaned MAF
Cleaned Throttle body
Throttle Position Sensor
Had car reprogrammed
So I pulled the belt off and checked all the pulleys and did notice some grittiness in the AC pulley (inner) and was wondering if this might be the issue. Attached is a video I uploaded, Video .....

I have a 2003 dodge grand caravan with about 111,000 miles on it. Overall it has been a reliable car. In the past month we had to replace the ECM because the computer died on the car. Now, very intermittently, while driving at about 60 mph the car will suddenly drop to 40 mph then shoot right back to where it was at 60. This only happens for about a second and then its fine.
Its quite startling but it has only happened to us 3 times in the past two weeks, so its very hard to replicate. There are no engine codes and it seems like the tachometer does not change during this sudden drop, although to be honest I wasn't paying that close attention to it when it happened.
Could it be related to the recent ECM replacement? The dealer "reprogrammed" the computer so I'm assuming all parts electrically have been checked.

As I accelerate, there is a humming noise that comes from the transmission area of the car. It does not make the noise when I am in idle, nor if i put the transmission in neutral and rev the engine.
When driving slow the noise is very subtle. As I accelerate faster the noise gets louder. The noise becomes the loudest at 60 mph. Above 60 it seems to calm down some. The noise is like a constant, deep humming sound. The noise gets softer as I slow down and then is gone when at idle again. To me it seems related to the speed of the tire or the CV half shafts turning or something rubbing in the transmission as the car goes faster. However the sound doesn't change when the transmission shifts. It stays constant and only gets louder as I go faster and then softer as I slow down.
While driving and turning hard to the left the sounds almost disappears until the car straightens out again. I have replaced the struts on all four wheels and this seems to only have caused the sound to get louder. I have also inspected the CV joints. There doesn't seem to be any cracks or signs of wear to all 4 joints. And I repacked the bearings.
The only other things I can think of is the cv half shafts are actually bad and need to be replaced. Or the motor mounts are not aligned/worn out and need to be replaced. Or the kickdown band and low reverse band on the transmission need to be readjusted. Or the transmission is has a problem (however it doesn't slip when driving).

I have a 2000 neon, a knocking sound has started only when I get on the gas a bit harder than normal from a dead stop. It seems to last only a few seconds knock knock really fast and then its gone, does not sound like engine knock (rocker knock or persistent knock) more like a mechanical noise. Where to start ? Front breaks were done 4months ago, new rotors / pads / and 1 caliper ...
Seems it to be worse now....now starting to lean towards broken motor mount ... how to check or where to find them. Also now starting to hear while braking.

Recently I have noticed that when on a tune other than stock I am getting a surge at idle - my RPMs drop to around 621-630 then shoot back up to 660-675. On my stock tune my RPMs stay around 640-667 and don't cause the surge (felt as a shimmy so to speak). Is there anything else that causes a similar symptom? I attribute it to tuning due to it only happening when running anything but stock but could be wrong.

I've had my 2000 Honda Accord V6 for about 3 years now and have had an idling issue pretty much since I purchased it. After driving for at least 50+ miles, and if its hot out it can easily have this issue as well, and leaving the car be for around 15 to 30 minutes, on start up the car drops RPMs immediately and dies. Multiple tries and it will do the exact same thing. Recently I found out a trick to make it work correctly which is revving the engine to 2000RPM for about 3-4 minutes, slowly dropping it down to 1500 RMP for around the same 3-4 minutes and finally down to 1000 RPM for an additional 3-4 minutes and letting off the gas. Usually after doing this the engine idles fine, car drives great. However, it must be noted that on Summer days with temperatures in the 85+ range, if I'm climbing (going up a hill for a long distance) the car might bog down on me, will not go above 50MPH and I have to pull off the side of the road for 45+ minutes before the car will run correctly again. This has happened about 3 or 4 times in the 3 years I've owned the car.
I would rather not have to rev the engine in hopes this fixes the issue each time so I'm wondering what could be the cause in the first place? I've replaced so many things including spark plugs, ignition coils, battery, idle air control valve, gasket, fuel pump, fuel pump relay and on. I gas the car up with Chevron gasoline, I've dumped in I don't know how many different fuel injector cleaners and have also tried Heet as well as Sea Foam cleaner. I've also had the car checked for vacuum leaks.
I've asked multiple mechanics if this could possibly be a vapor lock issue, but they all turn that idea down. They tell me that since the car is fuel injected this can't be the issue..but, I don't know, could it be the issue?
