I have a 99 Ranger w/3.0. It idles about 1500 rpm cold,and 1200 warm. Here are the things that I have tried.
1.Checked ALL vacumn hoses/lines
2.Changed Air idle control sensor
3.Throttle position sensor
4.removed and completely cleaned throttle plate in throttle body.
5. removed top of intake manifold and checked for cracks and/or leaky gasket.
Nothing seems to change. Could it be a faulty ecm?
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 RepliesMy 92 ranger, 2wd, 6 cyl, manual trans, is running at about 3500 rpm at idle. I was wondering what might be the cause, maybe something with the throttle or could the gauge be screwed up.
View 14 RepliesMy ranger 2.9 automatic 2WD has an high idle when started for about 6 min, engine can be hot or cold, still get the high idle, then it will drop to around 900-1000. I've changed the Idle control twice, checked EGR function. Replace temp sensor. Disconnected battery for 15 min. No code output.
View 7 RepliesMy truck has been doing this since I got it and I can't figure it out. It's a 2000 Ford Ranger XLT 2.5 5Spd. It runs fine if you don't rev it above 2500-3000 rpm. After you rev it that high coming down to idle it is stumbling real bad and sometimes stalls. I've been driving it like this since I got it, and it does fine other than this. It gets better the longer you drive it, but it still will do it if you rev it high enough.
Here are all the parts I personally have changed (previous owner said he did the plugs and wires and air filter, which it looks like he did but I'm about ready to change them myself):
-Fuel filter
-coil packs
-timing belt
-egr valve
-cleaned throttle body
-iacv
-tps
-thermostat
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 95 ranger 3.0L revs up over 2000rpm at startup then comes down slowly to a little over 1000... Changed the IAC valve still does it... When I let it warm up I unplug the IAC and idles normal and smooth about 750 RPM so I don't think it's a vac leak... What else could it be???
View 5 RepliesTruck is a 2003 Ranger EDGE 2wd auto w/140K miles (looks new) that was a one owner truck I recently bought. Came from Texas and is clean and was well maintained I got all service records up until I bought it in the fall last year. OK now the problems...
First...it has a high idle in the mornings when cold about 2000RPM. After it warms up it settles to about 800-900RPM but is VERY ROUGH to the point where it feels it will stall. I DID replace the spark plugs and the plug wires look newer and are not OEM. I DID remove and clean the IAC and it does not look very dirty but I did slightly clean it anyway.
When I did this I disconnected the battery for 20min. After I put it back together it ran smooth for about the first 10 minutes then same rough idle came back. I was told this truck has no EGR so that's not an issue. There are NO CODES and when I ran my pocket scanner nothing comes up either. Should I just go to NAPA and get a new IAC anyway? What else can I do?
My '03 Ranger is having a high idle problem. It's a 3.0, manual, 2wd, 141,000 miles. When it's cold it will idle at about 1500 but once I drive it, even just to the end of the block, it will idle at about 3000 and shoot up towards that between shifts. At a traffic light it will idle at 3000 and maybe go down to about 2500. If I bog it down with the clutch it goes right back up once I put the clutch back in or put it in neutral.
I replaced the IAC, no luck. I cleaned the MAF and checked the voltage on the TPS and it is good. I replaced the PVC valve, but the old one was fine anyway. I've sprayed around with carb cleaner and don't notice any difference. I've plugged it into my dad's AutoTap which lets me monitor everything on my laptop and the only thing I can see that looks suspicious is that even with the engine off, the Absolute Throttle Angle reads 18.8%. If I step on the gas with the engine off it goes up to 91.8% so I would imagine that just has to do with the function of the TPS and probably isn't out of the ordinary, but I don't really know what that number means or what the Absolute Throttle Angle is or is supposed to be.
Short of taking the intake plenum off and physically inspecting it for cracks, I'm stumped.
I have a 1997 Ford Ranger XLT 6 cyl. 4 wheel drive. I got this truck from a friend. Only had it for a month or so has about 185K on it but has been running great.
I did notice a couple times that when I pushed the clutch in approaching a light the truck would jump a bit in RPM to about 2600. but go back down in a second or two.
This started to occur more frequently and now it does it almost all the time....when I push clutch in it revs up to about 2600 RPM.
Now I can have my foot on the brake and let the clutch out to put some strain on the engine and knock the RPM down but its still a bot high in the 1k range. Sometimes it actually goes back to normal...
When I started it this morning it was fine....but after two shifts it started and lasted the 12 miles to work. What could be causing this? It does not seem to go above 3000 RPM when it revs.... Other then that the truck runs great.
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.
[URL] ... Looking for info on my 99 Ranger.
Here's what happened,I have an electric plow I hook to my Ranger every year with no problems,except this year. The day after hook-up my wife noticed no high beams, don't know if the two are related but I did nothing but connect the plow wires already in place. Anyway I proceeded to look for a fix, fuses first, replaced both headlights next, blinker/high beam/wiper lever-still no fix and to boot my truck doesn't ding when keys in ignition, four wheel switch doesn't work, & wipers don't work.
I've got a 99 Ranger. A month or so ago, it started to be a little hard to start. It would turn over, but not fully start unless I gave it a little gas. This did not happen all the time, primarily it happened after it had sat all day when I left work. Not long after that started, my check engine light came on. The codes were for a lean mix as reported from the 02 sensors. Before I could dig any further, it just wouldn't start at all one evening. This was after I had driven it for 30min and then parked it for an hour or less. But this time it was different in that the solenoid would just click, but that was it, like it didn't have enough power to turn over. I took the battery to have it tested and it had been severely discharged.
I got a new battery as that one had reached it's limits. Put it in and the truck started right up no problem. A few days later it started acting up again like it had originally, I had to give it some gas to get started. I had the alternator/starter checked, both were fine. A day later, it got so bad that I had to shift to N and keep giving it fuel anytime I stopped the truck. I had to do this all the way to and from work. Now this morning I go out and it starts right up, no issues, no dying at idle and didn't have bit of problem coming in. Initially we thought it must be a fuel pump, but then I can't explain why it worked fine this morning. I changed the fuel filter less than 2 years ago, so I wouldn't think it would require changing already. Wondering if there's a sensor issue, one that calls for appropriate amount of fuel?
I have had my '99 Ranger since 2002. Since it has started getting hot in Texas, the truck has decided to stall at horrible times. When driving on the interstate, there is no problem, but as soon as I get in town and have to let off the gas to turn or stop, the whole truck dies. Unless it sits for a long time, it will continue to die at every stop. It is harder to start each time. I have changed the fuel filter and added STP to the last tank of gas. Also, it is tough to start and keep running until it has warmed up on any day. I have to sit in the truck and keep the idle up so it won't die.
View 1 RepliesI just got a 99 2.5 rwd auto and it shakes when it's at idle in gear. I'm pretty sure its because the AC pulley is engaging drawing power. I was thinking about turning the idle screw up a blonde-one because when I hold the brake and give it slight gas it goes away.
View 3 RepliesMy truck is stuttering while idle and gets worse once it's in OD. My Check engine light is not on(yes it works). How to diagnose the problem. I don't know whether the plugs need changed, wires, fuel pump..
View 1 RepliesThe T/O bearing makes a high pitch squeal until you put light pressure on clutch then it will go away. Does this thing have a preload on bearing at all times or should there be free play like in the old days??
Another thing that has me wondering is when I push clutch all the way in it actually puts a load on the engine. Having T/O bearing so bad it puts a load on the engine?
1999 mazda B4000 4WD 178000 miles 5 speed manual, I've been having a crank no start problem but after a few tries it would start, a week or so ago it was really cold (23) it wouldn't start so I opened the air box and shot it with starting fluid it took about 5 long sprays but it started.
It ran up op 3200 rpms and won't go back down, took it to my shade tree mech. he hooked it up to the diagnose thing it showed no codes, he poured water over the motor it different places and toward the back it idled down for a second so he says "blown intake gasket' so we replace upper and lower and sure enough we could see where there was a bad spot on the upper and a cleaner spot on the port.
That was not the problem it still idles at 3200, I mean wide open screaming, could the starting fluid have done something? Now he says "blown head gasket" I never had any idle problems before matter a fact besides the hard starting problem that started it was running just fine, what happened?
My manual 5 speed 99' 2WD 2.5L Ranger is starting to have some small problems here and there. My main concern is when I start the vehicle sometimes, there is no idle. The vehicle will turn over and if I do not hold the gas pedal down it will die immediately after about 2 seconds.
If I hold the gas down so the RPM's stay up (Around 700 RPM's or so, something just a little above 0 to keep it from dying) after about a minute, sometimes few minutes the idle will kick in and I do not need to hold my foot on the gas pedal to keep the truck from dying.
This is about all I know from the problem besides that it does not matter how long my truck is sitting. For example, my truck was sitting for 5 days and I came home and started it up just fine, but after I drove it a few minutes later and stopped driving, when I went to drive it about an hour later the symptoms came back again.
Also, My brakes are acting a little funny. I went through when I first got the vehicle and bled the brakes, took the front rotors in to auto zone or another shop and had them fixed up, and new brake pads. Sometimes when I first start driving the brakes are extremely sensitive, to the point where I apply a little bit of pressure and my truck will start skidding. This goes away after driving for a little bit though.
I 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 have a 99 Mazda b3000 v6 that has recently started to stall whenever in idle. Check engine light is on and the following codes popped up (P0176, P0135,P0141, and P0155). I'm sure one of these codes has to be related to the problem but I am clueless when it comes to troubleshooting. Also it started stalling after I filled up the tank. Not sure if that has anything to do with it, check engine light was already on before that.
