Ford Ranger / B-Series :: 1993 V6 Miss At Idle And Running Down The Road
Apr 26, 2013
1993 3.0 V6 5 Spd ... Changed plugs wires Cap and rotor put in a new idle control Valve. No Check engine light. When i am running down the road feels like it surges,hickups, while its at idle the motor shakes like no tomorrow. Just dont want to throw money at something and not be the part that was wrong. Truck has plenty of pickup runs like a raped ape going down the highway. seems when i accelerate the miss clears up and not there. RPM gauge needle has some movement in it. Also put in K&N filter fuel filter as well.

Its a 1994 with 4.0, automatic, 4x4. Running fine, parked it, a week later I'm getting a bad but sporadic miss that according to the stealership is the 3 cylinders on the right bank dropping in and out. Driving down the road you can feel them drop out and when they come back its a kick in the pants like a turbo kicked in.
Shop says wires are good, plugs are good, and then lost me when they started talking around in circles and not making much sense.
What could make 3 cylinders all on the same side of the engine drop in and out? This wasn't anything that slowly came on. Fine one day, crap the next. The only thing I did prior to was replace the IAC because it was idling high, it was cruddy inside, and it looked like it was original. It was running fine after that till this issue popped up out of nowhere.
Mileage was claimed to be 178k but I'm beginning to suspect it's probably 278k.

I have a 85 bronco 2, but i have no luck with responses in Bronco 2 forum, so here goes. It is the 2.8 carb, manual trans with 109K miles. Idles really well some hesitation when taking off but really bad miss and not power under acceleration. KOEO codes are 31 and 84 CM code 18. I have plugged the vacuum line to the EGR and have noticed a dramatic difference. I have tried to rev the engine and check the vac line to the EGR but I do not feel any vacuum, and at idle the vac line on or off doesn't change things. Any recommendations to whether it is the Sensor or the valve itself and what gives with the 18 code. I am hoping to have timing checked by the weekend.

Engine 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.

1993 f-150 with 1988 5.0 with no pollution stuff fuel injected. here's the problem. Starts fine and idles great for about 5 minutes , check engine light comes on and it very nearly stalls at which point it begins to miss and surge and basically tries to die.
If I feather the Throttle i can keep it running but not smooth!! Can't find and vacuum leaks and the egr seems to be working (push plunger up - trk). dies. Ran fine when I bought it this way about 1 year ago and all of a sudden this. note.... It started doing this after it ran low on coolant but did not over-heat.

I have a 98 4x4 with 145k miles and 4.0 OHV. Symptoms are as follows;
Uses ALOT of oil. 1 quart per 230 miles. Burning bad in rear cylinders, some in middle cylinders, none in front cylinders. Screams intake or PCV issues to me, not rings or valves. Never any smoke, not even on startup. No significant leaks. MPG always 18-20mpg.
Slightly rough idle.
Miss under load below 2k rpm. Not a terrible miss, but you can feel it. Has never lit the CEL. I know the CEL is good.
Never loses coolant. No coolant in oil or vice versa. Haven't done compression test, but doesn't seem like they ever tell you much anyway.
This weekend I replaced all intake gaskets, plug wires, cleaned oil residue off and regapped plugs (they are 3 months old), injector orings, and PCV valve. Flushed and burped radiator.
It's too soon to tell on the oil consumption, but I thought the intake gaskets would have cured the rough idle and misfire. The idle IS much better, but still not perfect. But the low rpm load miss is actually worse now. Still no CEL. Could it be storing codes without lighting the CEL? Also, how do you clear codes on these, can you just disconnect battery, or do you have to clear them with a scanner?

2002 Ranger XLT 4WD 4.0.. I was passing another car at about 55 when they also started speeding up (go figure) so I floored it and got on around them but before I lifted I felt it miss, the CEL began flashing so I slowed to the speed limit and went on to work. The light flashed for about a mile then went out. So on the way home I floored it again close to home and the CEL came on again. Got home and put the code reader on it and all it had was a random misfire so I have cleared it. The truck has new plugs, wires, etc for a complete tune-up. I don't usually run at full throttle so don't know if that would be normal for the Ranger, the Ranger was my wife's truck for 12 years and now is my DD. Need to clear this up? Thought of changing the fuel filter in that is still the original one.

Just hoping that there is something common that causes this problem. This thing can idle just as smooth as you could want one to and the next time it will have a dead miss, and the miss is not consistent. It may miss like three hits then be ok a little then miss a little. There is no CE light or codes. Again just hoping there is something common.

1999 Ranger 4.0. I have an issue with my ranger. Sometimes the truck runs awesome.While driving along the truck will miss and sputter and buck, when this happens, I almost can't maintain my speed. Sometimes when this happens if I put the truck in neutral and shut it off and restart it. The problem will temporarily go away. Occasionally it will go away on its own. When it goes away on its own it's like someone flipped a switch and all power is returned and running smooth. When the truck is at idle it depends on the mood of the truck, sometimes it's fine and other times it wants to die. I got to make this truck last awhile longer.

How many O2 sensors does a 2.3 fi 4 cyl. have. I think just one on the manifold, but I'm not completely sure. Engine is running very rough and seems to miss at low RPMs, has no power and drinks gas like crazy!!! Emissions light is on on the dash. I'm thinking O2 sensor......tried replacing, but couldn't get enough torque on the sensor socket wrench to loosen, may be rusted.

I have a really nice 1986 Ranger XLT with a 2.9 V6 (injected) and OD Automatic with about 135k miles. I've had the truck for over ten years and have been pretty happy with it. I'm still trying to correct a couple of nuisance items:
1. Sometimes it runs smoothly, and at others it has a rough idle, and once in a while it will even stall. Before it stalls, it idles or runs roughly, and will miss erratically. When it quits, it does not fade out like it is running low on gas; it quits suddenly, like the ignition is turned off. If I am driving at highway speeds, sometimes it will buck as it misses, and sometimes stalls out. But it always starts up right away afterwards. This does not happen often, but when it does, it happens several times over hours or days, and then goes away by itself for months, even years, and then comes back for another round.
I was hoping whatever was wrong would totally fail, but it has been several years and is not getting better, nor worse. Fuel mileage varies, too, from 16 to high 20's MPG. I have new low- and high-pressure fuel pumps (dual tanks), new gas and air filters, checked all the electrical connections, put in a new ignition switch, new O2 sensor, Air Flow sensor, EGR, replaced all the vacuum lines, new battery and cables, new starter, all new electrical relays, fuel pressure regulators, new fuel pump inertia switch, tuned up engine (incl. wires, cap, rotor, ign module, plugs and timing), and cleaned out the already sparkling-clean tanks.
2. My oil pressure will drop at idle to low-normal when the engine is warm. It never goes to below Normal on the gauge. I have replaced the gauge, sending unit, and oil pump. This is a long-term issue, and is not getting any better or worse.

My 1993 Dodge Dakota quits running at any time, from right after start-up to going down the road. It wont start running again until the check engine light comes on when the ignition is turned on. I can sit there from a few seconds to five minutes before the check engine light comes on. I have cycled the key three times to check for a code, but there are none. I have checked much of the wiring to the relays and some to the PCM, but have found nothing wrong. This truck did the same thing with the two previous owners, and had the PCM replaced, to no avail.

I am starting to work on my 93 ranger when funds are there. But my question is do i need a Cat. for PA state emissions? I have heard you do but then I hear you don't. I have also heard a few things on the fuel millage and power.... Looking for some info on this because I am not trying to cut it off and have to go back and fix it again... I want to do it once and be done with that part!

Today on my way to work my 1993 ford ranger would shift fine but would refuse to go over 35mph and shook pretty bad. I don't know where to start...

Not only will it not go into gear, truck will not start unless clutch is to the floor, and in neutral (it's only possible place) if you pick the pedal up 1/4 inch off the floor the odometer starts spinning around 1 mile in 5 seconds.... if you lift it any more it kills the engine like you shut it off with the key.... odometer reads 99,004 miles now (the last 2 are mine) I bought this truck like this ....

I have a ranger as said in title. No a/c. I noticed my belt was cracked very badly so I bought a new one. Dayco made for Ford and Mazda 3.0L V6. Looked the same length as the old one so I put it on and all was good. Then about 2 days later it started squeaking very loudly, not all the time, just 1500 rpm and higher. The hotter the motor got (not overheating just to running temp) the higher rpm it took for it to squeak. I put a stethoscope on all the pulleys/pumps and alt. It sounded the strongest on the idler.
So I replaced the idler and bearing (which the bearing was bad, but not the source of sound) it wasn't that. So I thought I'd give the belt a couple days, maybe it was too tight causing a bearing to get too tight and squeak. And the more I drove it the louder it got with less rpm needed to make it squeak. So I tried belt dressing, and still no fix. So today I put the old belt back on to see if that was the issue. Sure enough, it started up and squeaked just the same, but I tried the belt dressing on the old belt and it went silent, even at 3000 rpm. So I assume from this the new belt was a smidge too big. Right?

How do you remove this clip holding the wiper linkage to the back of the motor? I can't see what kind of clip it is to know how to remove it. Ford says to remove the wiper pivot and let it drop. Is that necessary? I can't barely get to the back of the motor so I'm having to feel the clip and remove it but since I don't even know what kind of clip it is it makes it so much harder. Does the cowl cover not come off or is it just this access panel?

I'm new to the whole Ranger truck thing since buying a 1993 Ranger 4x4 for my 14 y/o son. It has a 4 inch suspension lift and a 3 inch body lift running 33x10.5x15 tires. The front sway bar is not hooked up. I know that i will need drop brackets for the sway bar but my question is about the end links needed for this truck. There are 2 tabs with provisions for a horizontal bolt on each side of the twin I-beam where the end link would attach and the sway bar has a single horizontal hole on each end. Searching for replacement links at various auto parts websites only seems to yield the standard end links that consist of a straight bolt with a nut on each end and the rubber insulators. That clearly is not the correct end link for my application. Not sure if the front suspension is the factory installed unit or if it was swapped some time in the part.
