Ford Ranger / B-Series :: 2003 XLT 4.0 Stalling At Stops / Low Idle
Dec 4, 2011
My 2003 ranger xlt 4.0 has a stalling problem. The engine light came on in aug and I had it coded at AutoZ and there was a code for the oxy sensor, changed that and didn't work so I took it back. In oct I had it coded and it said the air int temp sensor which i was informed was part of the mas airflow sensor, changed that the beginning of nov, got the computer to reset and it still didn't fix it.
Took that part back and had it coded again a few days later and several codes came up AutoZ code 1732 and the the OEM number to cross for them were: P2195 , P0300 , P0316 , P0174 , P0171 , P2197 . Reset the comp yesterday and as soon as the light came on had them code it again and it came up AutoZ code 1732 OEM # to cross P2195. I guess my next step will be to take it to the dealers to get diagnosed..

I have a 1995 ford ranger v6 4.0 and for this week Ive been having a problem, stalling... It only happens when I do quick "stop and go" driving. Even sometimes at stop lights it wants to stall, the only way to keep it going is to keep my foot on the gas.
Now for a while when its cold or my truck has been sitting for a day or two the truck doesn't start on the first click.
I've had the fuel pressure checked, changed fuel pump, and starter. I have no check engine light on at the moment. Tomorrow I am gonna check with my scan tool just to make sure. But, it could be fuel pressure regulator, idle air control actuator, egr valve? How I should go along doing this?

I’ve got a 1998 Ranger with 166,000 miles and it’s starting this weird idle at stops where the engine drops about 150 RPM’s and then fluctuates. The problem is intermittent and no pattern as to cold or warm engine. I changed the plugs and wires at 100,000 and the plugs again at 150,000, so the wires have 66,000 and the plugs 16,000. I really don't want to shotgun the plugs, wires and coil pack. I understand that vacuum might have something to do with my problem?

I started to have a slightly rough idle a while back, but not severe. I figured she was just aging a bit.
Changed plugs. Check engine light came on. Changed plug wires. Then I had a couple of episodes where it started to lose power and idle really rough (stalling). Both times it stopped after a few minutes. Had code read- they said it was coils. Replaced ignition coils. Check engine light still on, but it went a few weeks without power loss.
Tonight the loss of power returned and didn't leave, and I had a glowing red catalytic converter after I limped home 20 miles (hope I didn't do any serious damage, I was stranded.)
Found this post : [URL] .... But there's no resolution.
So, I'm probably dealing with a misfire, and I'm sure I torched my cat after tonight. So any other easy diagnose/fixes for a misfire? I'm a shade tree mechanic- so I know just enough to get myself in trouble. If I can't get a resolution soon it will be off to the mechanic (which, maybe I should have done 1st...)

I have a 2003 Ranger edge 3.0 flex fuel 183,000 miles. I have been having a misfire problem, only at idle, always cylinder 3. Replaced the fuel filter. Just replaced fuel pump assembly. With the old pump my fuel pressure was 49psi key on engine off, and running at idle it was 59psi with a shaky needle. With the new pump, when I turn the key on it jumps to 60psi then imedietly drops to 49psi, when the pump shuts off. Running it is at 60psi with steady needle. Koeo the pressure holds good at 49psi but does slowy decrease, about 5psi in 15 minutes. What would be causing the pressure to drop to 49psi? I am checking pressure at the fuel rail. Pressure according to the haynes manual should be 60-65psi koeo and the same while running at idle.

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.

Truck 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?

03, 2.3 duratec, 163k, new timing chain, plugs (AP104), wires and intake. cleaned MAF, air filter, and ran two cans of sea foam through the intake and its still pinging. its driving me up the wall. truck runs perfect but seems to idle slightly higher and take longer to come down to idle after I got the timing chain and plugs/wires done. I've sprayed starting fluid around on top of the engine looking for vacuum leaks but found nothing. What should I try next?

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.

Bought this truck a few months back. Nothing but problems. I always thought it has felt a little underpowered and hesitant. I chalked it up to being a 5.4l in a f250. Well now im thinking it has been a symptom all along.
Lately, the truck has been stalling at stops. Randomly, but not often. The truck idles at 750rpm when I start it, but after driving and then coming to a stop while in overdrive it idles at 400rpm. This seems too low to me.
It hesitates occasionally when giving it throttle. Just today it got really bad and was almost unresponsive. I would hit the throttle and it would just idle while randomly kind of shooting up in RPS and shuddering. It finally produced some error codes, it looks like, but I am afraid to drive it all the way to the autozone.
I am thinking TPS. Is the TPS attached to the pedal or is the TPS attached to throttle body under the hood? I've read some conflicting stuff about this. The good news is that if it is the TPS then it should act like a whole new truck after I replace it.

I have a 2003 f150 2WD crew cab with a 4.6 V8 engine it has 178,000 miles on it. The other day after I started it to leave work it died on me without hesitation almost like the ignition switch was turned off I tried to restart and it would turn over but wouldn't start so I switched the ignition all the way off and it started right up, going down the road it did it again.
If I try to restart without turning the ignition all the way off it won't start but if I turn it all the way off it will start up first try, it has done it a couple times since and its the same way every time, where to start. My check engine light has been on for some time for something else so I don't know if it picked up a code or not I don't have a code reader to see if it has a new code...

I have a 1999 ranger 4x4 , when I'm going to a slow final stop the abs kicks in ,doesn't do it every time , there's no abs warning light , took it to the ford dealer they scanned it and said it was the left front hub & bearing assembly, said the sensor wasn't reading the back of the bearing assembly. I can't understand way the abs light isn't on, is there anyway to clean that they want to replace the hub & bearing, Is a use hub & bearing replacement a good way to go? They told me I could pull the fuse and kill the abs, but I find three fuses I pull aII three and got a speed sensor check engine code. I hate to replace that hub & bearing when there's no problem with the bearing ,Is there any way to deactivate the abs, by the way it's 4 wheel abs.

I have a recently purchased 2000 ford ranger 4X4 with approx. 130,000 miles on a 3.0L. When I bought the truck, it was running rough while in gear at idle, after first putting it in gear, and when coming to stops, then it quit running all together. I started by replacing plugs, wires, and ignition module. I finally got it to fire up after that, but instantly noticed the tell tale white smoke from the exhaust. Needless to say, my oil looked like chocolate milk. Rather than having the heads machined and checked, I opted to purchase a new set of cylinder heads from Dover cylinder head.
I got those on this week and she fired right up. After a few oil changes to eliminate the residual coolant from the oil passages, she still starts and runs fine, although the idle is a bit rough while in park. When I place it in gear the idle gets a little rougher. After a quick trip down the road, I'm noticing a pretty solid shudder when coming to a stop, almost like it's stuck in 2nd gear, but I can't really tell for sure. Seems to shift fine going up through the gears, but coming down is when the issue is.
I believe I'm dealing with two separate issues, one being the rough idle upon startup that doesn't seem to go away, and two being the rougher idle upon stopping. I've read everything from EGR valve, idle air control valve, low fuel pressure, and a laundry list of other things, and I just don't want to start throwing money away chasing my tail.

Little back story, truck sat up for 2 years. Had 1/2 tank of gas in it that time. I had to do a complete motor swap. I been driving for past couple of days. Had it stall on me while I was waiting on wife to come out of store. Thought it was just bad gas. Today I was heading to town and had to slam on brakes and it started to stall again. It shut off. I cranked it back up and it runs fine till I start slowing down. then it wants to die.
I can keep my foot on gas petal and little and it will stay running. I got to where I was heading and put it in park and it idled fine for a few seconds and then I could hear a whine from the fuel tank. Sounds like the fuel was having a hard time, like it was fighting the pressure build.
Thing is It cranks right back up and drives fine as long as I dont come to quick stop or set idling for a few seconds. I can hear the pump straining, so I am assuming that when I keep my foot on gas a little the pressure is staying lower and not as much is being bypassed and the pump is fine. I think the pump is on its way out but wanted to hear what yall think.
I do have a brand new IAC valve that I bought and did not get a chance to use on the blown motor.

When I'm driving it starts to cutout (but it never dies) and it won't stop cutting out until I floor it and then it's fine for a little bit and it starts doing it again.

I am fairly new to this stuff but I just got a 85 Ranger 4x4 and its running pretty rough it will be fine then all of a sudden it will bog right out and want to stall so I have to keep my foot planted on the gas and it pops and spudders and eventually runs normal again? Its a 2.8 V6 carb...

My speedometer was intermittent for a while, stalling, then moving, but never above the actual speed. Now I turn it on, but as soon as I move, it travels up to 38mph then stays there until I turn off the engine, then it hangs for 4/5 seconds, then drops to zero.
I replaced the VSS in the rear diff, and the one on the tranny. I checked all fuses. There are no other dummy lights or indications. Bad ground? I'm hoping I don't need a new gauge cluster.

It's an oldie, 1984, but so far still kicking. 6 cyl 2.8, carb. I took a little couple hundred mile trip a few weeks ago. Rolled back into town no problems.
A few days later I took a ride and the ranger would stall when approaching a stop sign or light. I would hold the pedal down a little to keep it running but it sounded like it wanted to die if I didn't feather the pedal to rev a bit.
I drove a few days later, as I was going down the neighborhood road(25 mph), it acted like it wanted to just die. I mashed the pedal and it had no effect. It didn't stall and eventually I could rev the engine to continue.
It continues to do the same, then will all of a sudden take off like there was never a problem. If/when it does stall again, it can be hard to start until it does start and off I go again like there was never a problem. Other times, it will idle.
Another note: Sometimes when I go to start the engine it will stutter, intermittently turnover. It has done the same thing while actually driving, kind of a jerking deal.
Fuel filter, fuel pump, electrical? I'm going to first check/replace the fuel filter tomorrow.

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.

When I am at idle, the compressor keeps turning on and off every few seconds. It seems to work fine while driving. What do I need to do to fix this?
