Neon :: Car Started Revs Itself While In Park


Mar 31, 2013

My car seemed to drive home fine but when I put it in park to open my garage it started revving really fast and the check engine light came on. I could barely get it into drive and then it didn't hardly want to stop once in drive.

Dodge - Neon :: 2002 - Revs Up In Park After Throttle Body Cleaned Out

Took my car in to get the tire and headlight replaced. Not my usual mechanic. While they were in there, they took it upon themselves to open up the filter and root around the throttle body. They said it was heavily gunked up, and asked to clean it. The car has been having serious starting issues, so this made sense to me, so I overlooked them examining a part of the car that had nothing to do with what I'd asked them to repair, and told them to go ahead.

Mechanic cleaned out the throttle body. Now he says there are scratches in it, he suspects from a mouse or rodent. Says it needs to be replaced, but he couldn't source a part today. Either way, I can't afford that. Says it's fine to drive, though.

Whatever they did, the car is now worse. Engine revs up high in park or when I start the car, and then drops dow and keeps revving rhythmically while idle. And I swear that while in drive, it's running faster even with my foot off the gas, and not dropping out of higher gears as fast. I go back and confront the mechanic. He says yes, that's all because of those scratches. But I don't understand how before, when it still had these scratches, WASN'T clean, when it was, in his words, all gunked up, it was working BETTER than it is now, when it's clean and just has those scratches?

Santa FE SM (2001-06) :: High Revs While In Park

05 Santa Fe, 2.7 liter, 71,000 miles

Prior to today it had revved high, up to 3000 RPM, once or twice upon start-up but then settled down once I started driving it with no issues at stop lights.

Today, however, no issues upon start-up but within 1 mile it started acting badly. Pulls strong under load, i.e, accelerating. Once cruising speed is achieved and the right foot is relaxed, it loses power, slows and bucks.

At stop lights revs are down to below 800 while in drive and is slow out of the gate. When put in neutral at stop lights, it revs to 3000 then falls to 2000 then back up to 3000. It does not stall.

Replaced the IAC and it ran fine in park for exactly 2 minutes then began revving again.

Dodge - Neon :: 2003 - Car Started Overheating

My 2003 Dodge Neon started overheating. We replaced the thermostat, temperature sending unit, flushed the radiator, checked for blockages, cleaned the radiator, changed the head gasket and water pump.It can run for about 10-15 minutes driving or 30 minutes idling before it overheats. The fans will kick on. The thermostat opens up. Pressure builds up on the radiator hose. When it gets hot, it boils back into the reservoir.I've been careful not to let it get into the red since the head gasket change.We sent the head off and had it planed.

Mazda - Protege :: 1999 Revs In Park - Won't Go Forward In The Morning

I have a 1999 Mazda Protege. In the mornings when I start my car, it revs in park, but the rpms go down when I put it into reverse and back out of my spot. When I put the car in drive, however, it will not go forward for at least 5 seconds (time has been increasing). I can press the gas and the engine will rev, but it takes a long time to actually get my little car moving forward. Is this a new transmission problem? I love this car and live in fear of having to replace it.

Touareg :: V8 - Metallic Clanging Noise Above 4500 Revs Either Driving Or In Park

I have about 2000 miles on a new V-8 and there seems to be a loud tingy noise if I really get on it say above 4500 revs either driving or in park. It seems to be coming from either the catalytic converter or exhaust area. It is a very metallic clanging noise that is very audible outside the vehicle under heavier throttle positions, almost like a metal plate hitting another piece of metal.

2004 T-Reg V-8, Black, Conv, Xenons, Park, 19's,SS2

Ford Escape / Hybrid :: 2001 - Revs Up To About 3000 RPM When Started Cold

I have a 2001 Ford Escape. When started cold, it revs up to abt 3000 rpm. Slowly drops back to about 1000 in abt 10 secs. When the engine is hot, it often wants to idle 2500+ rpms and I have to really step on the brakes to slow the vehicle. When I disconnect the IAC the engine dies. When it is revving high, I can disconnect and reconnect the IAC quickly, and the idle will drop back down for a few minutes, until I step on the accelerator, then start climbing again. It seems to be a lot worse when hot.

I replaced the IAC and TPS about 20k miles ago and thought it was fixed, but the problem has returned. At that time, I could tap on the IAC and it would "get well" for a while. Tapping on this one doesn't seem to change anything. No CEL, engine runs smooth, and I don't notice any air leaks (none that I've found, at least).

Nissan - Sentra :: Engine Revs Up To About 1500 RPMs When Started After Parked On Slight Downhill

This is just a basic Sentra 2.0L with a CVT, about 80k miles.

I park on a very very slight downhill grade.. very slight.. almost flat.. The car starts just fine, put it in reverse, push the pedal to the floor, engine revs up to about 1500 rpms (I'm assuming it has a limiter on it because it won't go past 1500) and the car sits still. Release the accelerator, floor it again, car moves about 6", repeat a few times and eventually I can back out. That ain't normal.

It does a similar thing when in Drive, except it will actually start moving but very slowly. So slow that I'm afraid I'm going to get T-boned if I try to make a left turn. Once I get up to about 10mph it starts to feel somewhat normal.

Once it starts moving it doesn't seem to have any trouble maintaining highway speeds. The engine might be running a little faster than normal, but to be honest I'm not sure if it is or not. Pulls up some pretty significant hills at 60mph at around 3k RPM.. which seems reasonable.

What it could be? Transmission is still under warranty so I'm hoping it's that.. I don't really have the $ to throw at this thing right now. By the way - it's not throwing any codes or anything.

Pickup - Chevrolet :: 1998 - Cannot Get Out Of Park After Truck Started

I have a 98 chevy truck and shortly after the mechanic put brakes on my truck, when I start it you cannot get it out of park. In fact sometimes when I can't get it out of park when I shut it off I have trouble removing the key from the ignition. I've found that when I want to start it I turn the key one notch put the truck in neutral and continue starting. At this point all works correct.

Elantra MD (2010-15) :: Started Fine But Wouldn't Shift Out Of Park

Went to start the car today and it started fine but wouldn't shift out of park, and the instrument panel lights were out. Got it towed to the dealer and they narrowed it down to a junction box or instrument panel cluster. They won't know until tomorrow what the problem is. What this might be?

Nissan - Rogue :: 2008 - Shifter Will Not Go From Park To Drive Position After Car Started And Foot On Brake

I have a 2008 Nissan Rogue that is experiencing a shifter problem. The problem is that periodically the shifter will not go from the "park" position to the "drive" position after the car is started and your foot is on the brake. I have been able to drive the car by inserting a small screwdriver into the slot on the gear shift assembly to depress the switch that allows you to override the mechanism but as you can imagine that is tedious and what do you do if suddenly the screwdriver is lost - you go nowhere and you can't even get to store to buy another one because the car won't move!

I have had the car into the dealer twice now and they have been unable to correctly diagnose the shifter problem. They have said that it could be a failed solenoid that senses the brake pedal being depressed but so far that has checked out fine. They also thought that it may be a brake sensor and they asked me to keep an eye on the brake lights to see if they come on when the brake pedal is depressed and the lights do come on so they believe that is not an issue. They "repositioned" the shift assembly in the car center console thinking that it may be an improper position and they tightened it down into place but that has not corrected the problem either. They now tell me that the entire shift assembly needs to be replaced at a cost of $670.00 and I find that hard to believe let alone pay for!

The car has about 70,000 mile on it and it was recently in an accident that did deploy some side airbags and I am wondering too if the accident may have damaged the assembly in some way that caused the malfunction where the repairs may be covered by my insurance company. This has only started after the accident repairs were made and we never had a problem like this prior to that event.

Elantra HD (2006-10) :: When Put In Park Car Kept Rolling Like In Neutral And Started Making A Loud Grinding Noise

I have a 2007 Elantra with 138,000 miles. I never had any slipping or jerking or reverse issues in the past. I got into the car put it in reverse just fine then put it in drive and nothing happened, I put it in park and the car kept rolling like in neutral and started making a loud grinding noise. When I put the transmission in any other gear the noise stops but will not move and acts as if in neutral.

Ford Ranger / B-Series :: Truck Started On Its Own / Wouldn't Shut Off And Starter Engaged In Park

So I turned off my truck the other day, got out, and it started again on its own. Confused, I looked in my hand to see my key. I got back in, and tapped the brake thinking the command start had engaged, even though I did not have the remote with me. It continued to run. So I put the key back in the ignition, turned it to ON and back OFF. It still ran. I had to run inside for a half a minute so I left it running.

Came back and drove away with no issues. When I stopped again about 2 minutes later and shifted to PARK, the starter engaged making it's terrible 'hey stupid, I'm already running' sound. I tried shutting it OFF quickly but it still ran and made it's skinning crawling noise. So I quickly shifted back to DRIVE. All the gears worked fine but PARK and NEUTRAL had the starter engaging. I also could not shut the truck off from DRIVE as the key would not turn.

I drove over to a local garage and called them from the truck as I was effectively trapped in the truck with my foot on the brake, unable to shift to PARK or turn it OFF. No supporting staff. So I drove back to work where I had a co-worker remove the battery cable at which point I was able to shift to PARK and turn OFF the truck. I let it sit like that for about 10 minutes and haven't had a problem since.

What happened?? And for the record I can put gas in the tank and changed my own oil, but that is the extent of my vehicle knowledge.

Park Avenue :: 1992 - Hard To Shift Into Park From Other Gears

1992 Buick Park Avenue, Base. For awhile now I've had trouble shifting into park from other gears. Sometimes, it'll flow right into park without trouble. Other times, I have to work it, to kind of baby it in. However, it simply will not shift into park from reverse. Period. If I'm in reverse and want to park, I have to go into drive, neutral, etc, and then try to move it into park.

A mechanic I know looked at the neutral safety switch and thought it could be causing the problem. We figured it wasn't in the steering column or the cable to the switch because if we disconnect the cable, you can slide that lever all day long. So I purchased a new neutral safety switch and had him install it, but the same problem is there. Actually, let me clarify: while it was in his garage, with the old switch, it would no longer go into park at all, regardless (kind of decided to just stop altogether). At least with the new switch we can baby it into park, but it is basically back to where it was last week. He mentioned it might be deeper in the transmission, but that's out of his league.

Neon :: 95 - One Out Of Four Cylinders Won't Fire

1 out of the 4 cylinders won't fire. The coil, spark plug wire, spark plug, fuel injector, and the wire going to the fuel injector all work.

My dad mentioned it could be a stuck valve, but he doesn't really know much about cars and I have never messed with valves before. If I could manage to get to a valve and it is stuck, do I have to pry on it to unstick it or grease it up? Or does it need replaced?

I forgot to mention that there is no new noises and the FPR isn't showing the fuel line is holding pressure when the car is off, even though I'm pretty sure it used to.

Dodge - Neon :: 2005 - Won't Go Over 60 Mph?

Intermittently (although lately it's pretty common, perhaps due to the Texas heat?) my car will take several seconds to start. It sounds like the battery is dead, i.e., it sounds as if it's about to start but it straining, and then it eventually engages.

When this happens, I know that a) I won't be able to turn on cruise control and b) I won't be able to accelerate easily. at best I can get it to 60 mph

Similarly, even if I start up without a problem, and I'm cruising down the HWY at 80 MPH, the car will suddenly loose momentum and won't go above 60 mph. And I can't turn on cruise control (cc shuts down, in fact, if it was on).

This is a 2005 Neon, by the way.

I have replaced the battery and cabling to the battery to no avail.

Neon :: Speedometer Would Just Go Dead - No MPH Reading

Several years ago, a tree limb fell on out Dodge Neon, breaking the windshield. At that time, the dash gauges worked fine, and continued to for at least a year. Then, every once in a while, the speedometer would just go dead. no mph reading, and the odometer would not register either. over the last several years, it has become more prevalent, and is not not working more than it is. the other gauges are also intermittently failing to read as well. the scariest thing, is when it does come back, the air bag light comes on for about 5 seconds! which to me means there is a possibility that if we were in an accident, they might not work at all.

I believe the dash circuit board is cracked, and this is why this is happening. If the actual dash has to come out of the car, which is what i have feared all this time, it will have to stay that way until we get rid of the car. i can not lay on my head (upside down with my head under the dash) for hours on end trying to find and remove all 40 bolts or plastic clips or darts, or what ever they use these days to hold a dash assembly in. How to replace that board (gauges)? Can it be done without removing the dash? i have a Haynes service manual for it, but we all know how bad those are. I would like to repair this, but i can not afford dealers labor rates, and my luck with home grown shops has been poor at best.
