Ford - Thunderbird :: 1993 - High Idle Around 2500 RPM
I have a '93 Thunderbird 3.8 v6, auto trans, that was a great running car until I had the water pump replaced. So, I got the pump replaced and then 1 day later the car started to idle around 2500 rpm. It would hit about 45mph without even giving it any gas. I swapped out the mass air flow sensor for a new one. This brought the idle down a little bit. A month later, it shot back up.

I have a 2003 T&C 3.6L with tow package, purchased used (privately) with 25K miles in 2006. Since I have owned it, it will occasionally not go into any gear when first started after sitting at least overnight- basically stays in neutral until engine is revved to about 2500 RPM. You can rev it in neutral or while it's in gear. This always works, and the transmission will then work fine until another overnight stay. I have had the transmission serviced 3-4 times (once when it first happened, and then at recommended intervals. The car now has 96K on it, and it has been happening less frequently (in fact, it hasn't occurred in about two weeks). I have discussed this with two Chrysler dealers, and have left it overnight twice, but of course it didn't repeat at the dealer. I haven't been able to correlate when it happens with anything except: it seems to occur more frequently when garaged in Pittsburgh than when sitting outside in Myrtle Beach (I spend time in both places).
View 3 RepliesFord - Thunderbird :: 1985 Turbo Coupe Dies When Coasting In Neutral
This problem has plagued my '85 Tbird Turbo Coupe for about a month. When I put my car in neutral while moving, the RPMs fall significantly below idle and then the engine usually catches itself and after about 5-10 seconds idles normally. If I do this at high speed (say 40 mph +), the RPMs fall to the point where the engine stalls and dies. If I do it at 25-40 mph, it will go down about 200-500 RPMs and then catch itself. If I do it at 15-20 mph, it will be just barely noticeable, and anything slower than that I can't notice it. It will also do this to some extent when I'm stopped if I rev the engine up really high and let it off, but it is far less noticeable. This car has had extensive work done to it in the past 6 months.
Most recently, I had the fuel injectors replaced, throttle body cleaned, IAC valve cleaned, and the vehicle searched for vacuum leaks. (most of that in search of the solution to this problem as well as to improve the general performance of the vehicle. A week before that, I also had a new fuel tank, fuel pump, and fuel filter installed. I've got a very small leak on the back of my muffler, no cat, and no other exhaust leaks I can find. I am getting a lot of black carbon out of the exhaust, but I have been running some fuel system cleaner through it. Also, the car sat for like 8 years before I got it, and the original cat became clogged and really gunked stuff up. I had all of the upper engine gaskets replaced, as much as we could get to cleaned internally, and the cat cut off at that point. Timing is very close to 10btdc. Could be 9.5, but just about right there. I double checked, no vacuum leaks that I could find with a can of carb cleaner. I tried checking for codes, but it's not even throwing me a confirmation code or anything, which is odd. But, my connector was pretty gummed up (I did clean it as good as I could) and just about anything wiring is suspect. I used two engine code readers that had previously been used on the car. Other than this, the car has plenty of power and runs fine down the road.
Here's the master list of what I've replaced in the past 6mo:
FUEL SYSTEM Fuel Pump (twice) Fuel Pressure Regulator Fuel Tank Fuel Injectors
ASSORTED FILTERS Fuel Filter (twice) Air Filter Oil Filter (several times) Oil Filler Cap PCV Valve
HOSES/COOLANT SYSTEM Nearly every Vacuum Hose Every Coolant Hose Heater Core (twice)
SENSORS AND COMPUTER STUFF Engine Control Module (ECM) Vane Air Meter (VAM) Idle Air Control Valve (IAC) Oxygen Sensor
STARTING SYSTEM/ELECTRIC/Misc. Spark Plugs and Wires (Motorcraft) Starter Solenoid Coil Pack Distributor
TFI Module Distributor Cap and Rotor Battery Timing Belt
EEC Relay Ignition Switch Tires Front Brakes Brake Master Cylinder (had previously been damaged) Front tie-bars Every gasket from the head up.
Ford - F150 :: 1989 - Idle Dies When Put In Neutral Or Gets Stuck At 2500 RPMs
I got an old 1989 F-150, manual, in-line 6 engine, with an 8-foot bed. I use it for hauling landscaping equipment, as i am starting a business. i will likely start hauling trailers with it this summer, but I also just want the engine to give me more power.
What are some things I could do to up the HP, or a better truck in general. I'm not looking to make it into a 350Hp monster, just get a little more out of it. What can I replace or add that would do this?
First, the idle dies on me when i put it in neutral, or gets stuck at 2500rpms. is this a vacuum leak, or the idle-air control valve?
Passat (B6) :: Idling On 2500 RPM On Neutral
I was going downhill. And I accidentally popped the car in neutral. Its a 2.0t fsi automatic transmission. And after putting it back in drive mode. The car went to 2nd gear and jerked the tires. I had to put it back in neutral because it was revving high rpm and it wouldn't switch. After I came to a full stop. The car was idling on 2500 rpm on neutral. I got an intake installed and replaced the pcv valve with one I got from ecs tuning last week. I am assuming I have a transmission problem.

View 7 RepliesPrius (2004-09) :: Sudden Loss Of Traction Power And Engine Races
I have a Prius 2005 with an Engineer 4kwh kit installed [v4 bms]. Lately, I have experienced several instances where the Prius suddenly looses much of it's traction power and the engine races, and the red triangle and engine service lights go on at the dashboard. This happens with the kit turned on, and often after a few kit on/off cycles to get more ev mode. The Prius battery is sometimes low, sometimes not, when this happens. Not sure if it also occurs with the kit off.
The Prius seems to retain some traction power up-down by the throttle pedal, but most power goes missing. On the other hand the engine races and does not seem to power the wheels or vary by throttle. When I pull off the road using brakes normally, and turn off the car/engine and restart [kit now off], the car seems to reset and can resume driving normally, but the error code lights [triangle-engine] lights stay on.
Buick - Century :: Shut Off For No Apparent Reason While Idling / Engine Races After Restart
I had this problem a few times in the past. Sometimes my 1992 Buick Century will shut off for no apparent reason while idling. When I restart it, the engine will race for a few seconds before slowing down to normal idle speed. Could this be caused by a glitch in the car's computer?
View 5 RepliesChevrolet - 3500 :: 1993 - Truck Starts Surging / Tachometer Jumping From 2000 To 2500 RPMs
Mechanics say they don’t know what wrong… I had some transmission work done on my truck – mostly an leak and replacing the harness – and ever since then after it rains or if we have a heavy dew my truck does the following:
Driving from O to 49 miles an hour truck is fine, as soon as I hit 50 the truck starts surging and you can see the tachometer jumping from 2000 RPM to 2500 RPMs. I drive around 17 miles to work where my truck will sit for seven hours. On the way home the truck is fine. I find this to be more of a problem when the truck has sat for a day or two over the weekend without driving it. Sometimes the “check engine” light will come on, sometimes not.
I have taken it to two different places and neither one says they can find anything wrong with the truck. I have driven this truck for over 11 years and know it very well. There is something wrong, but what? 1993 Chevy Silverado 3500 Diesel....
Ford - Thunderbird :: Misfiring / Engine Struggles To Accelerate
I have a 1995 Ford Thunderbird with the 4.6 V8. I have owned it since it was a year old, it now has 70,000 miles on it. A couple years ago it developed a problem while driving. Hard to explain, but seems like it is misfiring or there a fuel restriction somewhere. This shows up when i floor it, the transmission kicks down and the engine struggles to accelerate, you can feel when it clears up, the car shoots forward. It seems like if i smoothly step on the pedal it is better, but not always.
This problem is also noticeable when the revs are low, like just before the transmission shifts down, like when climbing a hill, you can feel a shudder, if i accelerate and the transmission shifts so the revs are higher the problem goes away. Also, shutting off the overdrive so the revs increase works too. It really feels like the engine to me, although it does not go as far as to backfire.
2 years ago i replaced the auto transmission and torque converter with a factory one direct from Ford.To diagnose what i think is an engine problem i have: replaced the fuel filter (wasn't dirty) removed the injectors and had them cleaned and tested (they were fine) checked the fuel pressure (fine) checked the vacuum (fine) removed the exhaust to look for cat blockages (nice and clean) replaced the plugs, wires, and coils checked that the timing was in spec, although i don't think there is a way to adjust it
The car has the early version of OBDII - it does not have any active errors.
The car starts and idles fine, cold or hot, and when it is not acting up, still has excellent power. It does sit inside all winter though.
Ford - Thunderbird :: 1991 - Intermittent Spike In RPM With A Lurch In The Engine
I get an intermittent spike in RPM with a lurch in the engine when I'm holding anywhere from 1500-1700 RPM. I say it's intermittent because it might happen three or four times over the span of a few seconds, and then nothing for a minute or two. I don't think it's the transmission because it doesn't happen during shifting, and I can duplicate the problem in D, N, and P. What could be causing the problem?

View 4 RepliesFord - Thunderbird :: 1979 V8 Suddenly Not Starting / Engine Turns Over But Stalls When Key Is Released
I have a 1979 Ford Thunderbird with a V8 5.0 liter engine. Here's the mysterious problem... the engine turns over when I turn the key but stalls when the key is released. Thinking that the alternator died, I replaced it with a new re-manufactured unit and the car's symptoms stayed the same. Also checked the fuses and the fuel filter and found that plenty of fuel is getting to the carburetor. This issue with the car not starting appeared literally overnight after I attempted to install a new radio. Prior to this the car ran reasonably well – always started easily and ran without a problem. Wondering if there is a possibility that I fried some part of the electrical system when I fussed around with all the wiring under the dash. Someone else had attempted the radio installation previously so the wiring there was already a mess of cuts and re-connections and was hard to sort out.

My 93 Honda Civic (manual T) is starting to be difficult to shift into gear. I mainly notice it when the car is idle and in neutral. I go to put into 1st or reverse and it won't go. I try all gears at that point, and it's the same. When it finally does go, it's a loud thud-like noise. People around look over at me! It doesn't happen every time, but I am noticing it more and more. And it's a bit scary when I have been at an intersection or something and I can't get moving. It has 189k. I have also noticed that the car is loud, too, when I am in reverse up our driveway and the clutch is slightly depressed.

View 1 RepliesFord - Explorer - Transmissions :: 1998 - Engine Surges At Constant 2500 RPM
I have a 98 ford Explorer that has some serious trans problems. It all started a while back when I was pulling a small 10 foot trailer and when I go to where I was going the trans puked out what looked like all of its internal fluids. It was a hot day, and these problems seem to be exacerbated by the heat but who knows. Yes the check engine light is on. I also have the occasional O/D OFF light blinking at me. As of late the vehicle has started to act like it has a stall converter on it. I have to rev to nearly 3k RPM before it will engage.
I changed the fluid and filter about 2 months ago and the fluid is already grey and nasty. The vehicle has also started going FORWARD in ALL gears, Reverse, Neutral, etc. all are forward gears now. The trans occasionally overheats and pukes out a large amount of fluid but I cannot tell where it is coming from. At road speed (55 MPH) the engine surges when it is at a constant 2500 RPM. I know my outlook is grim but if I just need a new torque converter I would like to know before I go the the Salvage yard for a different transmission. BTW. The engine WAS replaced around 12,000 miles ago with a donor engine from a flipped vehicle.
Accent RB (2012+) :: Can't Travel At 15 Mph - Jerks / Surges And Races Then Slows Down
I live in a community with a posted speed limit of 15 mph. I travel a full minute at 15 mph before I exit the community to a city street. My 2013 Accent Hatchback won't "glide" along at 15 mph. It jerks and surges and races and slows down. I've tried using the manual option and keeping it in 1st gear however, when I reach the 1st gear tachometer limit at 15 mph the car "stalls" and the tachometer needle drops out and the car slows to 5 mph.

Truck: 2001Ford F350 5.4 auto 4x4
Issue: Engine seems to free rev over 2500 RPMs. Barely hits 50 MPH. Revs fine in park, no power in gear. At 1/4 throttle it will move, but sluggish at best. Once you get around 2500 RPMs it stops accelerating and just revs. Does this in every gear, and gets worse the faster you go. feels like its stuck inbetween gears almost. No CEL's
Replaced: MAF, TPS, Trans fluid and filter, fuel filter, cleaned intake system, fuel system treatment, O2 sensors. Trans fluid was dark, but no burnt smell.
I'm about to pull the exhaust and look for a clogged cat.
