Ford Ranger / B-Series :: Extremely High Idle At 2500 To 3000 RPM
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. ??

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.
Ford Ranger / B-Series :: 1987 Won't Idle / Motor Revs Up Then Cuts Out Completely And Dies
I have an 87 ranger that has started having problems over the last week or so. I had a similar problem a year or so ago. I put a new fuel pressure regulator on and it fixed it. So it started acting up again so I got another regulator and it didn't work at all. It won't idle at all without dying. The motor revs up then cuts out completely and dies. It's like I'm repeatedly pressing the gas pedal when I do get it to idle but I'm not touching it at all. It runs fairly well on the road until I let off the gas then it goes to shaking and jumping up and down till I get back on the gas.
A guy told me to unplug a little cigarette pack shaped plastic box and see if it changed anything. I think he called it a map sensor? But that didn't do anything. I was thinking maybe the fuel filter was clogged up but I don't really know. It is fuel injected 2.9 4x4 regular cab. About 110000 miles. Not sure if filter has ever been changed. It doesn't smoke or smell like gas so I'm thinking it's starving for fuel.
Ford Ranger / B-Series :: 1998 Won't Go Over 3000 RPMs
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.
Ford Ranger / B-Series :: 2003 4.0 - Rev Limiter At 3000 RPM / AC Clutch Not Engaging?
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.

Ford Ranger / B-Series :: 1996 Truck Idles From 500 RPM And Randomly Jumps Up To 2 - 3000 RPM Then Back Down
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.
Ford Ranger / B-Series :: 2006 - Running Fine Then Cuts Off?
I have a 2006 2.3 ranger motor runs fine at idle and as I ride down the road the motor just cuts off. If I pump gas it will take off again and in 3 miles it will do it again. After 20 miles running good it will cut off again. Replaced coil pack, fuel pump, Cam sensor, Idle control sensor! What else could be causing this?

Here's my problem I have a 02 ranger 3.0 with some problems and I need to bounce it off some one with knowledge.
1. starting and normal running fine / ok .
2. In drive at 2200 rpm t0 2800 rpm the engine is sluggish and at night the head lights dim about 30%
3. Sometimes the battery light will turn on during this problem.
4. The only code is for a air leak fuel / evap system .
5. Above 4200 -4500 rpm the engine staggers or cuts out.
Parts changed coil: / ECM, Fuel pump and filter, plugs & wires several relays and alternator.
Inspection: Checked most ground and common grounds, looked for damaged, cut worn an burnt wires or worn harness plug / connectors .
Ford Ranger / B-Series :: Engine Cuts Out While Driving - Continuous Memory Code 22
1988 Bronco II - 2 days ago while driving my check-engine light came on for about 5 seconds, though there were no apparent drivability issues, then went away and did not come back for the remaining 20 or so miles home. Then yesterday while driving to a destination the engine cut out a few times. Gauges and such stayed illuminated but the engine lost power as if it wasn't getting fuel or spark. It occurred randomly over a 3 minute period: 1 second bogging, then 10 seconds powering, 3 bogging, 20 powering, 2 bogging... I depressed the clutch to check if the engine could idle and it stalled. Then I restarted the truck and drove 5 miles home with no issues or check engine light and even driving for a minute at WOT would not make the issue remanifest. I did not drive it today for fear of breaking down and I hope to get this solved before taking it on the road again.
I read the following codes:
KOEO: 11 (passes)
Continuous Memory: 22: Manifold Absolute Pressure (MAP) or BARO sensor out of range.
KOER: 11 (passes)
Ford Ranger / B-Series :: 1998 - Cuts Out While Driving - Throttle Position Sensor
The Problem: When I start my Ranger it dies right away, I do this about 10 times or so (worse when it is wet or has rained) then I can finally keep it running, by hitting the gas. Once I get it running it will cut out while driving as well. The idle is normal and if fires properly, I just took it in to the shop (non-dealer) and they said it fires normal and has normal fuel pressure, and the their computer returned no error codes. Their sugestion was replace the throttle position sensor. Do you all think this part could be the cause and where is the this sensor and is it hard to replace?
View 12 RepliesFord Ranger / B-Series :: 1999 - While Going Uphill Cuts Back / Looses Power And Jerks?
I have a 99 Ranger 4.0 4x4. When driving on a hill, the truck cuts back and looses power. I can press the pedal and go into passing gear and it will pick up speed but that is the only way the speed will increase and not slow down. The truck jerks when this happens.
Things I have tried:
Replace all plugs and wires
Replaced Coil Pack
Replaced Mass Air Flow sensor
Replaced O2 sensor
Replaced throttle cable
Took truck out of overdrive
Changed to better grade of gas
Changed oil
I had Cat. Converter checked
There are no codes showing. Truck may drive OK on one trip but act up on the return. It seems to use a lot more gas when it is acting up. I now have run out of options that I know about.
C/K :: 1999 Chevy 5.7 MT 2500 - Engine Cuts Out While Driving At 3000 RPM
MT 2500 Where are you I've got a weird one. 99 Chevy 5.7 dully dump truck. The engine cuts out while driving at 3000rpms only. If you keep your foot in it it goes away at 3200. Does it in any gear(auto). Also, stopped and in park, it will do it at 4000rpms. Acts like a rev limiter. Fuel pressure does not change (60-62psi) when this happens, does it in open or closed loop. I disconnected the maf and no change. I've installed new cap, rotor, plugs, wires, coil, module(all original with 165K), no change. Runs sensational until 3K rpms.
View 14 RepliesFord Ranger / B-Series :: 1990 - CEL Only On At Idle
I recently acquired a 4.0 Ranger 4X4 Auto for my use in Costa Rica. It runs fine but it'll illuminate the CEL within a few seconds of starting and whenever revs fall below approx 1000. When pulling off the line or accelerating, the light will go out but comes back on when the throttle closes. The previous owner has replaced the MAF and idle air valve. I've corrected a lot of issues with the vacuum system and think it's back where it ought to be. I know I am going to need to pull the codes but I'm back in Dallas now and can't do it yet. Need general list of affected parts that I could buy here and take back down.

View 14 RepliesFord Ranger / B-Series :: IAC Open Up And Raise The Idle
My 04 ranger is back at it AGAIN. It started about 3 years ago.
- Cruising along on the highway and then come into town. Idles at 2000 RPM
- Shut it off. and restart it. Again, 2000 RPM.
- Shut it off and it idles normal
- Drive it 2-3 day and then it idles high again
- I have clean and functioned the IAC and it works fine
- Cleaned throttle body and I never can get it to stick.
- Replaced throttle cable
It still was idling high
- Replaced ECM and it idled normal for about 1 year
- Replaced em again and it idled normal for about 6 months
It is back at it again. For what ever reason the EM is telling the IAC to open up and raise the idle...
Ford Ranger / B-Series :: Strange Sounds At Idle?
Allright, I seem to be having these very strange sounds at idle. Mostly when I am in Drive and waiting at a red light. In Park, it isn't as bad it seems.
One sound is knocking. A kinda slow one and irregular. Not a motor knock tho. Doesn't sound like that. It also kinda clicks from under. So, those both sounds come from under or the sides of the truck.
Should I worry about this? I've had these sounds since I've got the truck. Sometimes louder than usuall.
Ford Ranger / B-Series :: 1988 - Won't Idle - Starts Right Away Then Die?
88 ranger. 2.9L manual. Just bought this truck. It ran great when I bought it. After a day or 2 it would idle rough. Almost die but it wouldn't. No check engine light. It seemed to do this intermittently. Some times I'd start it and it be fine. Other times I'd start it and I'd expect it to die at each stop light.
Now for the last couple days it dies on every start up. It won't idle. It'll start right away and then die. I can keep it going by keeping the engine rev'd but the check engine light is one. If I keep it running and start driving down the road it'll drive with the check engine light on for about 5 minutes. Then the light goes out and it runs like normal, even at idle, until I shut it off. Then it's the same story at next start whether it's right after I shut it off or hours later.
It doesn't seem to matter whether the engine is hot or cold. When the check engine light is out, it runs great the rest of the time whether at speed or at idle. To me it sounds like a sensor is on it way out. I figure if it was vacuum, it happen at every idle, and if it was fuel it happen all the time or at least every idle. Tried to get a code at parts store but the reader wouldn't work. It couldn't tell it was plugged in the the truck for some reason.
