Plymouth - Neon - Airconditioning :: 1995 - Running Very High Idle?
Jun 20, 2015
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.

I have a 95 neon SOHC that drives with a very high Idle. Not all the time, but 85% of the time witch i find strange. This has been going on for the better part of a year and the car is almost undrivable. Its putting a hurting on my breaks for sure.
I had replaced the PCM 5 years ago. Replaced the timing belt 2 months ago. I have searched all around for vacuum leaks but am not able to find anything. I pulled the throttle body off and cleaned it very well. I replaced the IAC.
The car continues to idle out of control as if the IAC is wide open. The only way to get the car to idle correctly is to cover the idle hole in the throttle body 90% up with my finger. The guy at Auto Zone said if its not IAC or vacuum hoses, then I should start replacing sensors. How do I diagnose this problem?

Ok, ready for a new head scratcher? After replacing the starter, the battery cables, the camshaft position sensor, several hoses that were broken and/or disconnected, a wire for the transmission "forgot the name of it, but technically it was a cable with a piece of plastic that connected to the throttle", air filter, spark plugs, spark plug wires, battery temperature sensor, ignition coil, several missing fuses, I got a new code.
This code came up and I believe it is the same code that came up before, but I think it got masked by the battery temperature sensor and the "random cylinder misfire." It only appears when I reach speeds of 60 mph or above, the code is P1899 and when I took it to Autozone, Oreilly's, and Dick Poe Dodge, they were unable to figure out what the code meant.

1993 Plymouth Voyager LE 3.3 V6 Automatic. Bogging down when entering an incline, keeps running in idle, will bog down, if dropped in low it will take off, sometimes backfires. Runs very good when on level ground. What can it be, mechanics suggest fuel pump, transmission, had it checked out by my mechanic and the fuel pump is fine, doesn't seem to be the transmission either.

I own a 1987 Plymouth Horizon, 70, 000 miles on it. Long story short, The car sat for 3 years without being driven. It would just be started up whenever the other owners wanted to. I have fixed a lot of its problems, and replaced tires, brakes, hoses, belts etc.. Problem I am having is when itis started up it is at a very high idle and will not allow you to kick it down till it warms up or it idles down on it's own after being warm. I have sprayed carburetor cleaner around the linkage and so on but it still does it. What could be causing it?
Like I said the car sat for 3 years and did have gas in it when I bought it and not being able to drain out the old gas I put HEET gas-line antifreeze & water remover in it. The fuel filter has been changed out twice. Once you get it on the road it runs like a champ for being 24 years old. It's just the high idle when you first start it up. The owner of it had some little quirks I guess you would say. He had and they are still there, two clothes pens on the gas rail/line and they were there because of vapor lock. They are located on two different parts of the line I guess to balance it out. Now I don't know if this is true or how even remotely possible two clothes pens could have anything to work with vapor lock. Now I do know that on occasion it will run a bit and stop when you cut off the engine, though not all the time....

My neon has a leak that was diagnosed today as a rear main seal. I realize this is an expensive repair and am wondering two things:
1) Can I limp it along until next Spring by adding oil as needed?
2) Can try stop leak additives? If so, which one?

I have a 1998 plymouth neon that is leaking oil from the filler cap, I have replaced the cap 4 times and it still leaks from this same spot. What it might be?

I noticed a knocking sound from my 1996 Plymouth Neon when I hit some bumps. Poked my head underneath and see what appears to be the strut loose inside the spring. I am afraid that the "Damper Shaft Nut" came undone somehow? If so, how do I remove the quick-strut? Is the spring in danger of being sprung?

When I changed the alternator on my 2000 plymouth neon, I crossed the wires for the plug. Now the fuel pump fuse keeps blowing, when it turns over, which isn't often. I turn the key and nothing happens.

I have a 1998 Plymouth Neon that will start after it has cooled completely, and be fine through out the day, but when I get home from school and I start it again, it makes a strange screeching noise, and after turning off the engine and trying to restart the car, the vehicle will not start again, but all of the lights work, the battery is fine, the alternator is okay, the starter is a brand new OEM part, new ignition coil, new spark plugs, new safety neutral switch, new speed sensor, new battery cables, new camshaft position sensor, the only extra thing it does have is fog lights that were not put in by the dealership, this was done when my uncle still owned this car back in 1999. The only other problem that it has is an Error code of P1899 (Safety/Neutral Switch Stuck) and at times when turning the steering wheel, it will make a screeching noise halfway turned until you let go a bit, and then it is able to completely be turned either way, and one last thing is that the speedometer was a bit erratic one time, while I was driving home on the freeway.

The A/C in my 1995 Taurus SHO stopped working suddenly on my way to work. I found that the compressor clutch was no longer engaging. I tried tapping the clutch with a broom handle while the car was running and the A/C on to see if the clutch would engage and indicating that the gap my be too wide but I had no luck.
I then hooked up the guages to check the charge and performance of the system. When I removed the service hoses both service ports were leaking gas. I tried to poke them with a small scredriver to get them to seal but that didn't work. I ended up losing the entire charge.
The service ports in the A/C lines do not appear to be schrader valves. There appear to be small rubber balls in the port that seal. However I knocked one of the apparent balls loose and found simply a flat plate in the service port. I am certain that it is not a schrader valve unless one exists under this plate.
Are these service ports repairable/replaceable or do I need to replace the entire hose assembly?

The equipment:1995 Buick Regal Custom 3.8
I noticed a year ago that my car would randomly stall out coming into work after a 20-25 minute drive. It then started to idle really high, very rarely. So i cleaned the throtle body, new air filter, new fuel filter, sparks, and wires. This is about where my expertise ends.
Its seemed better, however, it would act up now and again (stall) but I was fine with it.
Recently I have noticed that the car idles really high 1.5 in drive (compared to 900) and 2k in park after I have drove for 20-25 mins. So I put the computer to the car and all I have is transmission error codes which I have had since I owned the car at 80,000 miles and I am now to 160,000 miles. This car has been pretty good to me because it starts, goes forward, and backwards! What else can you really ask for. A better idle maybe?

I have a 1995 Plymouth Voyager se about a year ago the transmission started acting up, for no reason, it would just go it to First and never come out I would stop turn it off turn it back on again and it would be fine..then days later it would go by, it would do it again. it did this for a while and the good days would turn in to a mile or two then it just decided not to come out of first ever, during this, i took it to a trany shop and rebuilt the transmission it worked for a bout a half hour.
Final a mechanic friend checked the computer again and changed it out with another and it fixed it beautifully!!! ok well about a week ago a very odd loud obnoxious squeal started that sounded like a bottle rocket but not all the time, more often than not though. Before I got a chance to take it to my mechanic friend i was driving along and the transmission slipped in to first and wont that's it. i have been doing emergency trips in first gear and also the horrid squeal is gone. the thing have to be linked what should I try and i don't think its the computer, I really don't want to lose my van

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.

1995 Honda EX with 150,000 miles. Its been running rough ie rough idle, stalling at low rpms etc Additionally for awhile now when humidy reached north of 85% the car wont start. It cranks but rarely runs.
Took it to a mechanic last week for a tuneup. They replaced the Distributor cap, spark plug and wires and fuel filter. Car ran great for a day. Then progressively got worse. Was undriveable the other day stalling misfiring while at speed. Took it back today. They determined that it was still not getting spark and replaced the distributor. They did so, test drove it, declared it good and I came to pick it up. Paid the bill, walked out to the car and the damn thing would not start. Humidity was high.
Mechanic pulled a spark plug and put a tester in and didn't get a spark when cranking. He is assuming the distributor he just put in is bad. So they are keeping the car overnight to be fixed in the morning with a new distributor.
However I'm not convinced the dizzy is bad, I believe, as I've read that the Honda's ECU is probably bad and shorting out in the high humidity. Can a bad ECU would prevent spark?

Recently replaced spark plugs and wires on 02 SL1 with 209K miles. Was running rough, rough and high idle, almost died on me driving home one night. After replacing everything, car still wouldn't start. Spent some time on the forums and some suggested a leaking intake manifold gasket, so I changed that out as well as the coolant temperature sensor. Still it won't start. I am getting good spark at the plugs (coil arcs across the posts when plugs wires are off).
Really not sure where to go next with this. I can hear the fuel pump hum when I turn on the ignition, and I get a good spray at the fuel rail. Basically I turn the key and it cranks, sputters, and will almost catch, but then not. What next??

High pitched noise when car is running at idle and when not on the gas. Whenever I accelerate it goes away. Pitch/Loudness seems to be higher with RPM's. Could be coming from front of the car.
Checked so far:
I read some other posts about this and fully disconnected my aftermarket radio. I'm pretty sure it is not a ground loop as no power to HU shouldn't still create the whistle.
What I have:
I have an EIP aftermarket street exhaust. I checked the exhaust to see about the flapper, but I don't believe I have any of the items involved - maybe I'm wrong. After some more reading it sounds like a vacuum leak as it goes away upon acceleration. I need identifying what vacuum hoses are still in place/clamped off with having an aftermarket exhaust.
I do not have a CAI, just a K&N drop in.

The car will start up fine, run for 10 - 20 min and stall. I will try and restart it but i takes atleast 7 or 8 sec of the car just turning over before it slowly fires up. Which results in a high idle 1200-1400 rpm and the car stalling another 5 min later.
Ive fixed my o2 sensor the wire was cut, replaced the fuel filter, and got a eurojet lower pcv hose for the vacuum leak i found.

Went to the dealer because my idle was running both too low and/or too high, check engine light came on.
1) Replace air intake manifold because air flow flap is faulty.
2) Oil leak out of upper and lower timing belt covers - need to replace gaskets.
3) Missing!!! the high note horn

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!!??
