View 1 RepliesThe trucks seems to Idle Rough in Park and Drive, Cold or Hot. It mellows out as soon as I give it gas but at stop lights or in park it goes back to a seemingly rough idle.
This is my first Ford Ranger and dont know if its normal. No code or dummy lights.
2007 2WD 4cyl
"95, 2.3L, automatic. Stalls for a couple of seconds and nearly dies when shifting from drive to neutral or from drive to park. Doesn't do it when cold at high idle or when AC is on. It catches back up and idles fine but nearly dies when coming out of drive. Installed a new idle air control valve but no change.
View 1 RepliesEngine runs rough at idle. Two plugs are black and just replaced head gaskets. I installed new short block and new heads six months ago. I can't seem to figure out the problem and I would like to trouble shoot more before tearing heads off and going any further.
View 2 RepliesI understand there is not much adjustable on my 98 Ranger (2.5L) as far as idle speed and mixture. It runs rough when started cold. Is this a sign to replace spark plugs?
View 2 RepliesMy gf's dad said I could have his 07 Ranger 4.0 2wd with 230K on the clock if I fix the tranny 5R55E. One day he was driving home and all of a sudden had no drive. The tranny will run thru drive, neutral and reverse, but has no drive to it. Engine revs with nothing to show.
Tranny fluid was very dark and pan had nothing but the usual "metal flour" in it. I stopped there, did not pull the filter or anything else.
Well all is ok now but I am not one to ignore or forget a symptom. After a long drive into the city over Christmas I pulled in to park at my destination. It was idling rough when I stopped. Vibration my be a better adjective but not too bad. It did not feel like ignition etc, not MIL on and putting it in Part did not change it. I shut it off and went inside for the festivities. Started it for the drive back and all was ok.
Whether some bad gas with water got in or something else I don't know as it as above freezing but I got thinking about this dam harmonic balancer pulley may have had on the 3.3L go. I have seen some post in in 2006 as well with this engine in other models. I got some 47L of quality Shell gas later on as well for the drive home days later. Still no issues but... IT HAPPENED AND I DON'T FORGET so I am thinking about it.
Is this a major problem on SF's some went as early as 30k from the owers. I had no other indicators and I doubt there is going to be much to see in the space with a light.
I'm getting tired of the same problem about every 6 months. Plug #4 keeps going bad. Its been doing this for years. It starts with rough idle when first starting up that clears up quickly then eventually it leads to a misfire when accelerating. Every time this happens I replace plug #4 and its good to go. Just recently (roughly 6 months ago) did a full tune up and all new injectors. About a week or 2 ago it started its rough idle at start up and just the other day it started misfiring again. What would keep causing this??
View 14 RepliesMy 2005 2.3l Ranger ran great. I moved a trailer about 150 feet and stalled the truck backing it up. Stick shift. Unhooked the trailer and pulled back into the parking area....all the sudden the truck has extremely rough idle and stalls. It runs good on the highway. AutoZone ran a OEM number to cross: P0171.
I cleaned the IAC with intake cleaner. No Luck
I unhooked battery for 15 min. No Luck
I sprayed intake with 1/2 can of intake cleaner. No Luck
I did not have a tamper torx to remove the MAF. What next.
168K, to date, replaced

This 2003 ranger 3.0 v6, run very hard at idle, yet it runs and you can drive it around town, ""at"" low rpm, and no hills but it gets from point a to point b
I have no pre ingintion, but a plug that was only 60 days only was burnt out completely on 3rd cyl. bank 1 or as ford call it #3, i am telling you this thing seem like it running on 4 cyl,s kicking back and forth, and replacing everything above made no difference.
On the highway, as long as it is flat or down hill 75-80 mph, as soon as a hill or power to pass is needed it bogs down and slows it self to about 45 mph, I have been though everything i can think of and my next move to to start pulling heads, but i wanted to ask here first.
I have a 2002 ford ranger xlt 3.0 i just rebuilt the entire motor about a month ago and was having a high idle problem for the longest time. turns out i had the iac on backwards. but now that it idles down around where its supposed to it has a rough idle has a little shake to it. starts up right away but when i drive down the road around 3000-3500 rpms its missing on cylinder #3 from what the code I am getting "multiple cylinder misfire, #3 cylinder misfire" I've replaced plugs and wires. camshaft pos sensor. I am getting 65 lbs of fuel pressure. spark on all cylinders. I am really at a dead end here. Also every time I take the plugs out to look at them they look brand new.
View 14 RepliesSo I have a 2001 ranger 2.3l . Runs very rough at idle.code says misfire in cyl.#1. I have changed plugs, wires, coil packs all motocraft. I did a compression test..
#1.170
#2 180
#3. 185
#4 . 180
Compression seems fine,but where do i go from here? Anything else i can check/replace to solve this?
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.
View 5 Replies1995 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?
View 3 RepliesI have an 02 ranger xlt 3.0, it started having a rough idle, codes say cylinder #2&3 misfiring, changed plugs, wires, coil pack, didn't work, still same code, checked injectors on right side, all 3 had ohm reading of 15.8-16.5, the injectors were clicking like they are supposed to, sprayed carb cleaner around the intake ports, didn't change the idle at all,what else can I check or do? with out tearing the engine apart, unless of course I have to, the truck has been very good to me, it's got 205,000 miles on it, I need it to last at least another year...
View 4 RepliesI have a 1999 B4000 4.0L with 160K miles on it. Bought the truck new. Up until about a year ago it ran perfect but has developed an idle, stalling and occassional jerky ride problem. It occurs at any temperature, engine hot or cold, A/C clutch on or off and in Park, Drive or Neutral. When you start the engine it will not idle unless you keep your foot on the gas. The idle speed will drop to 200-300 rpm and the engine dies. Sometimes you can barely tap the gas pedal and the rpm will shoot up to normal idle speed (about 900 rpm) and stay there a few seconds then begin to drop again. If the engine is cold it will often die a couple times after starting even with the foot on the gas and then about the 2nd or 3rd time run with your foot on the gas.
At stop signs and red lights you have to keep your foot on the gas to keep it running. If you are approaching a stop sign and take your foot off the gas to coast to a stop and brake, the engine rpm will drop and the engine will die. It always starts fine though. Once you are driving it generally runs just fine at low or high speed. You can generally set the cruise control on the expressway and cruise right on. However, sometimes all of a sudden the truck will start bucking and jumping as if it has a terrible misfire. It usually lasts a few seconds and quits. Often if you step on the gas it quits. Even less occasionally the engine will begin to slow as if it is starved for fuel and slow down. You can press the pedal to the floor and it sputters a bit then picks up and runs fine.
I have read about all the threads in this forum and others and tried some of the suggested fixes but it still has the problem. I have tuned it up with new plugs, wires, fuel filter, air filter and PCV valve. Based on some of the forums advice I have replaced the IAC valve, the EGR valve and EGR Pressure Feedback Sensor, and cleaned and inspected the MAF sensor with MAF cleaner. I have checked all my vacuum lines and no leaks there and checked the engine timing which is fine. Fuel rail pressure and engine compression are also fine. Spark plugs show no clues, exhaust is clean and the engine uses virtually no oil. There has been no tear down on the engine like removing the heads, cam, timing gears or any of that and the engine is completely stock.
It shows no codes related to the problem. Two or three months after the problem started I showed a code that indicated an injector problem, traced the problem to a bad injector, replaced the faulty injector and it was fine. That took care of that code but didn't solve the idle problem. In my younger days I was into drag racing and I rebuilt engines, swapped transmissions, etc. and still do my own tune-ups today so I am fairly familiar with auto repair and have most of the tools for testing newer cars but this one stumps me. As a last resort I'm about to take it to the dealer.
I love my Ranger. I'm quite impressed with the power and durability. I'm ticked at Ford for stopping production.
I have searched my problem and could not quite narrow it down. I have also tried several remedies with no improvement. I need to narrow it down to a specific item.
2004 Ranger, 4.0 liter, 4x4, 131,000 miles, runs great above idle.
Problem: rough idle, idles at about 750 rpm's. If i raise the rpm's to 850 and up, smooth as silk.
The truck did this a few years back. Not quite as rough and it went away by itself.
Engine light came on this time with P0303 & P0316 codes. I have replaced: plugs, wires, coil pack. I know that the #3 plug is sparking quite well. the #3 injector is getting signal to spray not sure if it is. I have 4 O2 sensors and I believe I tested them correctly (passed). The passenger side upstream or pre cat sensor has not been tested yet. Had to rent a tool and will do that in morning. I slid a piece of aluminum roof flashing between the crank position sensor and the crank pulley. Not a noticeable difference. While at idle (750 rpm's) I pulled each (#3,2,1,) (one at a time) injector wire plugs off the injectors. No noticeable difference. I pulled the vacuum line off the egg and operated it with a vacuum tool. Seems to be working fine. Sprayed carb cleaner around on vac lines. No engine surge
I have an 87 ranger, 2.3 4cyl. 2wd 5 speed. When I start up the truck after it sits for a few hours it will idle fine but then it starts to bog down and wants to stall but after about 5 mins its fine and runs like a champ. I don't know if its a sensor or what.
View 2 Replies1987 Ranger and the computer will not communicate. I'm trying to check for codes because of a rough idle and stumble when starting out from a stop. Check engine works but won't flash when using a jumper across the data link. Used a OTC scanner but it only times out and comes up "no data". Where to go from here?
View 7 RepliesI have a 2006 Ford Ranger with the 3.0L v6. The check engine light came on and the code it is blowing is a P0171. It runs rough at idle or when I let off the accelerator and "fine" at speed.
The code told me to check/clean the MAF which I have done. Next on the list that I saw was the PCV valve. I disconnected the electrical to it and then disconnected the hose. Some oil poured out of it... not a lot but some... The valve still seems free, it clicks when I rotate/shake it and I can blow through it (I know, highly scientific). I can replace this (if I can find it, Napa and Advanced Auto don't have a part that looks like it...) but I'm wondering what else could be wrong.
I have a 2007 Ford Ranger 3.0TDCI when I drive on a road that is bumpy or on a ground road the ABS light keeps coming on , sometimes it just flickers other times it keeps on for about 5minutes. I when for a service 3000km back but they told me the brakes is fine. What it can be?
