After I got done with all of this crap on my Ranger, I noticed that it was driving great! But...today I was on my way to school and BAM! My engine idle started hitting (presumably because I do not have a tachometer) about 3000RPM and lowering down to about 2500RPM and from there, every time I am not in gear it decided to fluctuate between 2500RPM and 3000RPM. Crazy style too.
Now, I got to school, and getting closer to it at a stop light the truck basically died. It was almost at 100'ish RPM. I gave it gas, and BAM. I hear a continuous hissing noise from under my hood. Haven't diagnosed it fully yet because I just got home and its 12AM.
Now, every time I stop at a light or in traffic or whatever it may be, I have to give it gas every other second, like a small push on the pedal, to make sure the truck doesn't die. Also, every time I am out of gear and my RPM's are at an 'idle' state, I get continuous hissing from somewhere, I get no power loss or anything, just really weird idle RPM's and hissing when my foot is not on the gas basically. It is strange. I think It is some sort of Vacuum leak but I am not sure.
To get a better picture of the 'hissing' noise, it is the same hissing as you would hear when letting the air out of a tire. That is the best way I could describe it.

Ranger often wants to idle at 2,500 to 3,000 rpm. I'm glad its got a clutch! This is a long term intermittent problem that is getting worse. I have replaced the the IAC twice. I have unplugged the IAC when the engine is in high idle and the engine idles normally. But, starting the car with the IAC unplugged makes car run rough. That makes me think the IAC is not getting the right voltage input from the pmc (eec). Mine is a 2002 with the 3.0 engine. Throttle plate seems to be closed.
What sense inputs does PMC use to determine idle air position? Also replaced TPS sometime ago but that didn't work either. Sometimes turning off the a/c will knock the idle back to normal but not always. Turning the car off completely usually resets idle. But the high idle comes right back after accelerating. Drove the car today and idle would stick and stay high when clutch pushed in coming to a light. However. as the car slowed to a stop the idle would come down when rolling 1-2 mph. ??

I have been having with my ford ranger. I bought this off my nephew bcuz he needed some money and never drove it due to it being a 5speed and he has a kid and a wife and no room. OK the issue I am having is in gear or neutral I can't get the 2.5 motor over 3000rpms in any gear at all. If you rev the engine up or r driving it when it hits between 2900-3000 rpms the motor acts as if it is going to die and looses all power until you let off the gas. I have replaced the following items on the truck. Oh by the way I have a Cam 2 hand held and there are no codes or warning lights. All new parts :
1) new fuel pump
2) fuel filter
3)new timing belt
4)new motor craft platinum plugs
5) new motor craft plug wires
6)new Mass air flow meter
7) clutch,pressure plate & throw out bearing along with new slave(that needed it replaced others since I was there)
8) exhaust tube behind motor(rotted out)
9) new idle control sensor (acts as elect. Choke)
Truck starts up real quick and idles fine, but when truck is cold the rpms @ 2500 does the same as when it is warm @ 3000 rpms. I even took it to the local ford dealer in my town. Youngstown oh @ Fred martin ford. They told me the wires should be replaced and plugs along with mass air flow valve. I called them after replacing it and told them no difference and the service manager told me to bring it in again and they will look again. Service manager told me he has never heard of this type of problem and I went to a local garage mentioned it to the lead mechanic. He said that is why he doesn't like fords they are to common in chronic problems and can't be fix without a lot of guess work. I have a Hanes manual and did everything it recommends to no avail.

Driving a 2008 Ranger XLT 3.0. Starts runs and drives fine, how ever it seems to have a tinny ruff idle.
What I noticed is when in park or neutral when I idle it up @ 3000 RPMs it seems like it runs on 3 cylinders and sort of cuts in and out very quickly. Is this a protection thing on the ranger.
Running on the road it kicks down and runs thru all the gears normally from idle all the way up to 5000 RPMs. Just would like to make sure this is normal.

I have a 1997 Ranger with a 3.0 v6 with a super high idle.
It idles at 2500 RPM when the IAC is plugged and a steady 1100 when unplugged. I have replaced the IAC twice now (dropped the first replacement. long story) and and have also checked for vac leaks with no results.
After about 2-3 minutes of idling at 2500 on a cold start it will drop down to 1100 (same as when IAC is unplugged), but after a 10 minutes or so drive it will idle steady at 2500 with minimal if any dropping in RPMs. This is driving me crazy not only because it sounds horrible but also because of the fact it's burning through fuel like it's going out of style.
I have checked the MAF sensor and it looks brand new (not the original owner) along with the O2 sensor. I have been meaning to check the TPS voltage to see if it's working correctly but without a working multi-meter it's making it difficult to do anything.
I'm at a loss with this right now and because of all the previous repairs i have done to it and the others that still need to be done i don't have the biggest budget to fix this problem nor the money the truck is using in gas.

I've been getting a blinking engine check light.. I pulled all the codes:
P0050: H02S Bank 2 Sen 1 Heater Circuit
P0155: O2 Sensor Heater Circuit Malfunction Bank 2 Sen 1
P0304: cylinder 4 Misfire detected
P0688: ECM/PCM Power relay sensor circuit
I've had the car sitting for awhile because I lost my job and didn't have any money to roll it around much.
I just changed out the spark plugs and two of these had a white coating on them.. I was hoping this would take care of the misfire after I replaced them. I also bought a new battery because mine had lost charge a few times.
The Car will run with an engine check light, but if I go past 2500-3000 rpms then it will start blinking (which means don't drive it )
The oil has been sitting in it for about 2 months, so I'm about to go change that and I'm hoping this will allow me to drive it without issues.
Any of these codes thrown and know what they could be? Which O2 sensor (like a link to a website that sells them). Trying to get this thing running again.

I recently purchased a 2013 elantra.
I have noticed that there is engine vibration and noise felt in car and pedal when accelerating at around 2500-3000 rpm's before it shifts. Is this normal behavior? It just does not seem as smooth as it should be. I have only put about 600 miles on the car.
It has been very cold, but it does not go away after warming up.

1999 B3000 with a 3.0. The truck idles at 850rpms. When it starts it idles at around 1000 and runs very rough. When I disconnect the IAC the engine dies. The AC also has problems it blows cold at idle but at highway speeds after 7-8 minutes running the compressor kicks out. One can turn it off and it blows cold again after a few minutes.

1995 ford ranger with 4.0. It idles rough. Replaced MAF TPS fuel pump fuel filter fuel pressure regulator upper o2 sensor. IAC.. still idles rough RPMs drop. It isn't as bad since replacing MAF but still not right. What else is there.. Cleaned out the air intake port it was gummed up. Don't know what else to do?

My 1998 Honda Civic DX's RPMs are fluctuating during idle. I start the car and it is normal for about two seconds. I am assuming around 800 rpms (I don't have a tachometer). Then it jumps drastically higher, then lower, then higher, etc. Earlier tonight I replaced the throttle body gasket, replaced the spark plug wires, and cleaned the fuel injector cleaners. I took off several things in the process. I think the problem originates from taking apart the throttle body - not the other replaced parts. I have a manual 2-door 1998 Honda Civic DX with a 1.6L engine (D16Y7 engine to be exact).

So I have a 2.0 jetta and I'm having this problem where my rpms fluctuate at idle and sometimes the car dies unless I give it gas.but when I'm driving if I'm not in gear and stop it sometimes dies.
I'm getting 5 codes : P0445, P0135, P0037, P0418, P1473
I checked all my grounds I changed the 02 sensor on the manifold checked for cut wires and nothing ...

I own a Ford Ranger 2003, 5spd 6 cyl. My problem is when I'm driving and the engine is revving above 3000 rom's. It begins to sputter and buck as if the engine is running out of gas. It only lasts a few seconds. It ends as quickly as it starts. It does not occur each time when driving above 3000 rpms. My mechanic took the truck for a test ride and of course he could not find anything wrong. His advise was to wait until it got worse. I would rather solve the problem now. It is difficult and dangerous when trying to pass vehicles on the road.

I have a 1998 Ford Escort which I drove about 450 miles in frigid weather over about 8 hours in mid January. After arriving at my neighborhood and getting off the expressway, I couldn't get the idle on the car (manual transmission) to go below 2500rpm's. Further, upon taking off, the car was trying to stall, and I was forced to feather the clutch through town driving and keep the throttle up so it wouldn't stall, even with the clutch in. The weather at the time was about -7 degrees (f). The next day the weather continued, and thee car would start, jump to the same idle for 10 seconds, then drop suddenly to 500rpm, then stall out. I wrote the car off, cleaned it out over the next week, and then I tried to run the radio while doing so last weekend. I got the car to start, and run normally. I think it may be a computer issue, but it may also be the temperatures. The car has 207,000 miles on it.

When I start my 2003 Escape 3.0, the rpm's shoot up to about 3000rpms. After a few seconds they drop to about 2000 and slowly creep back up to 3000. When I put in gear, I don't even have to step on the gas and my vehicle goes. It maintains between 1500-2000rpms as I'm driving. When I come to a red light or stop sign, it lurches like it wants to go even though I have my foot on the brakes. I've replaced the IAC valve, TPS, had it checked for vacuum leaks, PCV valve replaced. I'm at a loss as to what it could be.

So that's what if feels like, in park at idle it sounds great, starts great no codes. IF you floor it it will not go over 3000 rpms in park, it feels like it has hit a rev limiter. I have 60psi fuel pressure at idle and at 3000 rpm.
When driving down the road I won't go over 55 mph and drives normal if you keep it under 3000 rpm, if you give it more gas it falls on its face?
AC is not working (clutch not engaging)I don't know if that's related or not.
We did just swap the motor the truck is a 2003 2wd drive. motor came out of an 2002 4wd. we are running the 2wd harness, computer egr delete etc.

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?

I bought a 2006 F-350 4WD Lariat SRW with a little over 200,000 miles on it. The truck seems to run perfectly, except when pulling a load (9,000-10,000 lbs) down the interstate/highway. Sometimes, when pulling above 65-70 mph for an extended period of time (45 minutes to an hour) the truck will all of a sudden idle down and won't get above 2300-2500 RPMs (even if you put it in neutral and floor it). It's not enough to shut it down, but it won't let the truck accelerate as fast as normal. Killing the truck and cranking it back makes it go back to running normal for a little while, but the periods of it acting up get shorter after each killing and restarting. I took it to the Ford place while it was acting up, and they thought it was a turbo problem. They cleaned the turbo and said everything looked fine, but the same problem arose after leaving the shop. They've been stumped at 3 different Ford shops, but one said there's a 95% chance a new turbo would fix the problem. What might be wrong?

So I just drove my 85 to san francisco and back to Los Angles this weekend to visit my girlfriend and i had high oil pressure all the way until i blew my valve cover gasket.
So i fixed it finally today and it ran fine for a couple blocks and then my rpms shot up to about 3000 rpm and wont come down at idle speed and the car wants to keep going while in drive.
Its a 2.4l 22re EFI

I have a 96 ranger with the l4. Right before I bought my newish truck last December, it's started miss firing and running really bad. I replaced the spark plug wires, most of the spark plugs, and both coil packs. Didn't work at all. Then I bought my new truck and parked. Fast forward to now. Fired it up, ran REALLY bad. We changed the wiring order from the 96 order to the 99 order.
But the truck idles from 500rpm (barely running) and randomly jumps up to 2-3000rpm and then back down. Driving it has NO power, rev it and it stays at 2-3000 for quite awhile. Sometimes it randomly dies. REALLY need to get it running quick and cheap. Getting ready to sell my daily driver to find something else and I need something to drive while I hunt for another truck.

My car is a 2001 honda accord v6. It sat for 3 winter months. When I go to turn it on in the morning, the car will rev while idling. Jumping between 1000 and 3000 rpms. Why this might be happening?

Had a first-time issue with my car today. Background, 2010 II bought in June, just short of 15K miles, never had any kind of mechanical issue.
While en route to work this morning, I was about halfway into my 15 minute drive to work, when I noticed my engine was idling very high, I would guess 2500 rpms. It started doing it while I was driving around 35 MPH, then continued doing it while I stopped at a traffic light, and continued when I continued driving to a speed around 50 MPH. The high idle while stopped was not transferred to the wheels, so it was not a safety issue as it would be in other cars.
When I got back up to 50, curious to try something, I hit the ECO mode button and the car returned to normal. I took ECO back off and the car was still fine. I had no further problems.
I would point out that this morning was about the coldest temp that the car has experienced. Outside temp ranged from 7 to 10 degrees.
