Ford Ranger / B-Series :: 1998 Mazda B4000 - Missing Enough To Shake The Truck At Around 80 Km/hr
Sep 13, 2017
So Im working on a 1998 mazda b4000, frost plug blew out going down the highway changed the engine because it got cooked pretty bad. The wrecker engine I got for what ever reason will only run good if the driver side of coil pack is done 5,6,4 any other order truck wont run at all. Misses enough to shake the truck at around 80 km/hr otherwise its pretty good. Also the engine I got came factory with no egr.... no provisions nothing. exhaust manifold capped off, seemed kinda odd.

So i just bought a b4000 pickup 5spd .. Anyway the truck has eletrical 4x4 with manual hubs. When i turn the switch nothing happens. The 4wd/4wd low lights both flash 6x then go off then flash again while running , driving, koeo, anytime like an obd1 check engine light code flashing. Anyway i checked the wiring for the 4wd switch no power, went to the fuse interior no pwr, went to the engine fuse box power. You don't hear the transfer case engage at all as well.

1998 4.0 ... She only misses about 30 seconds during stone cold startup. I figure it's probably the plug thats hardest to reach ? Isn't that the way it always is? From the hood I can see only one spark plug, so I figure I'll do all the plugs. Is there any right or wrong approach to the plugs? I did the thermostat today, but this plug job looks like it's gonna be a bitch. Time for some skinned knuckles Next is the right side O2 sensor, that looks like fun too. But I gotta say, this little truck is sweet. Great visibility and easy to park in the city. I really like her. She's a keeper. She needs some new sway bar bushings too, but no surprise with 127 K on the clock.

My 94 B4000 (4.0L ohv)is acting weird. If I let it sit for more than a day, it won't start. I pop the intake tube off, squirt some gas in the plenum, and away she goes. It starts all day long after that. I can hear the fuel pump running. Is there a possibility there is a fuel pressure regulator leaking down, kinda like a pump losing it's prime? Or am I looking at dropping the tank for a new fuel pump??? It's getting close to winter up here (gonna snow anytime) and I don't need this kind of trouble when it's cold and snowy.

This interference correlates directly to tire rotation speed, engine rpm has no effect. Under about 5mph it won't make the noise, but over that you hear a pop more or less for every rotation of the tire and when you hit say 50mph it is just a steady static noise on AM only. Haven't pulled the head unit yet, checked several body grounds under the hood and all are good. Don't know if a damaged wheel sensor could cause an issue or not.

I have a 1999 B4000 V6 4.0L with 78K miles on it. I recently had P0171 and P0174 error codes come up. I replaced the MAF sensor and have not had the codes return but now the truck will basically stalls out when sitting at a stop light. It does not do it all the time just randomly. It has never done it when engine is cool but only once up to temp. The idle is smooth at cold engine but begins to get rougher once warmed up (nothing too bad just noticeable). I cleaned the IAC with MAF cleaner but no joy. I reseated all plug cables at the coil but no change. RPM around 600-700 then fluctuates up a bit then truck will stall quickly( I usually cannot put other foot on gas in time to get it to increase RPM before it dies)....

I am having a problem with my O/D light flashing and my truck shifting hard. Just started out of the blue. After reading a few other topics, I am hoping it is the VSS. Now if only I could find the dang thing. Looking for a diagram, or detailed description on where it's at?

I have a 98 Ranger 4x4 XLT 4.0 5sp. It has 182K miles.
Once in a while it will blow the fuel pump fuse. It'll go 2 years sometimes. And sometimes the engine will stall just for a second making the truck "buck" as it accelerates.
Could it be the pump is about to fail? How long do they normally last? Btw, I change my fuel filter every 2 years, no issue there.
I've owned the truck since new and maintenance is always taken care of. Also, What's the best way to change the pump?

I have a 98 ford ranger with a 3.0 v6 it has 228,000miles standard tranny but I keep the truck running great. I did the plugs and wires about two weeks ago and it was running fine, actually great. This morning I got into the truck to start it this morning and it barely started. It fired up but barely stayed idling. I would get into the petal and it wouldn't raise rpms. I had to get to school so I headed out. I couldn't get any speed in gear the truck wouldn't gain speed. It would sputter and pop and then all of a sudden it would go ok but then start popping again. I took it to a buddy shop and his scanner showed p1131 and p1151 both codes. I don't know what to do?

I don't have a Ranger or B-Series, but I do have Ford's older B-Series counterpart. 1979 Ford Courier, 2.3L/5-spd. I have had a bad rear end shake since I bought the truck nearly three years ago, so I'm sure it existed well before then. It only happens around 60-65 mph, and there is also a kind of buzzing/humming sound whenever I'm coasting to a stop in neutral. I have:
Replaced and balanced the tires several times
Rotated the tires several times
Replaced all four wheel bearings
Replaced steering linkage
Replaced front suspension
Balanced driveshaft twice
Replaced driveshaft center bearing
Replaced all three U-joints
Checked rear wheel lateral and radial runout
Had the front end aligned three or four times
Checked engine and trans. mounts
And yet the issue persists. I am stumped and this problem is driving me bonkers!

After having my whole clutch system replaced..the truck now hesitates after 25mph shift 35, 45 and so, on it does not have a rough idle, it is like it has a hard time going then gets a burst of gas or air or will power and runs great till the next shift..,after replacing air filter, fuel filter. fuel pump & regulator, tps sensor co2 sensors and cleaning maf/map and fuel injectors, is using lots of gas too..the truck is still not happy, spent hours checking for pinched vacuum or fuel or eclectically lines.. Oddest thing, it won't throw any codes.. 1994 mazda b4000...

I have a 2003 Ranger 4x4 with the 5speed automatic. It has 215,000 miles on it and I don't drive it regularly anymore. Lately, I've noticed that it will shake after start up for 10-30 seconds. This only happens after it has sit for a few days or a week. After it warms up, I can drive it and stop and start it again and it has works as usual.
Is there some way the convertor is leaking out fluid and it shakes until the convertor is full again? Or is something else the problem. I've changed the fluid two or three times during the life of the vehicle.

I have a 2000 Mazda B4000 with 2 little problems I don't know anything about. First is when I go to start the truck it takes a long time to turn over. A friend of mine said that a valve is not maintaining fuel pressure so the fuel is not sitting ready for the starter when I go to start up. But if i engage the key for a few seconds and time it right it will turn over easily (apparently allowing the fuel pressure to build to the appropriate level). Is this a little valve or gasket or something I can replace to maintain the pressure?
Second, when I'm coming from a stop or accelerating out of a slow roll there is a 'shudder' or 'shiver' in the drivetrain that almost feels like the shift from 1st to 2nd is just kinda lumpy. It also happens if I come to an abrupt stop, so gearing down into 1st. It doesn't feel like something that is getting worse, but I don't want it to be causing damage or have my driveshaft snap or something.Other than that this truck seems really well maintained by the previous owner, and a mechanically inclined friend of mine said everything else looks.

I have a 98 Ranger with a 3.0 (5 speed) that has 254,000 miles on it. I drove it to town this morning (8 miles) and it ran normally. I stopped for just a few minutes at a house and when I re-started the truck, it was missing very bad and the CEL came on. It wouldn't haul itself in anything higher than 3rd gear. I decided to try to make it back home. I drove it less than two miles and it cleared up and started running perfect again. I came home anyway and read the code with my scan tool.
It said that I had a miss fire on cylinder #5. I erased the codes and shut the CEL out and its been running perfectly ever since. (I have put about 150 miles on it so far) If it does it again, I will start by replacing the plug wires. I have already done that but its been a long time ago. The plugs have been replaced twice as well. I was wondering if it could be something other than electrical like a dirty injector or maybe the compression rings lined up and it momentarily lost compression.

1999 ranger 2.5. 135k!So I started with a tune up all motorcraft, fuel filter and air filter. Did nothing! So I did compression check all cyc 150psi and above. So I did leakdown, had air leak at dip stick and valve cover, So I asumed head gasket. Pulled head and found 3 head bolts on passenger side had carbon deposit bluid up really bad, So replaced head gasket all surfaces clean and flat. Still didn't fix it!! My symptoms are better than before hd but still have a engine shake and flashing cel at 55 plus mph and p0303 pending! Coils tested good but going change them any way tonight!I'm stuck on this one checked everything 3 times and then again...

I've traced a 0.3-amp parasitic drain to the audio power amp (fuse #16, 20A). Pulling the fuse, the radio still works (it's on fuse #15) but then there's no sound from the speakers. (There's also no current drain. I'm weighing if it's more important for the truck to run or to sound good.)
I replaced the radio a month ago. It was definitely not working right, and the new radio definitely is. With the #16 fuse in place, the sound out of front and back speakers was great. "Was" because if I leave the fuse in, the battery gets drained in a few days, so the fuse is now out.
Where the audio amp is. My Haynes manual doesn't say. The amp has no user controls. It just takes the radio's output and feeds audio to the front and back speakers. The #16 fuse is what gives the amp power. Some online posts say it's under the glove box, some say behind the rear right speaker. All agree it's a bear to access.
So a few questions:
Why the power amp would be drawing current even when the truck and radio are powered off?
How does one troubleshoot this, short of replacing the power amp, which of course I don't have an extra lying around and wouldn't want to replace anyway as it's otherwise working great.
What do you think of installing a switch on the audio power amp circuit so that when the truck is parked, I switch it off, and no current drain, but when the truck is driven, I switch it on, letting me hear the radio or CD. This is obviously a kludge/ghetto solution, but the advantage is that I don't have to access or replace the audio amp. I want to keep using the fuse, of course, so am looking for a way to wire a switch into the fuse box while keeping the fuse in the circuit. If I knew which wire goes between the fuse and the audio amp, I'd splice a switch there, but I don't, and again, the Haynes manual is not useful.

I have a 2001 ranger 2wd with a 2.3. It has a miss when acceleration. There is no check engine light. I have changed: fuel filter. Plugs, wires, crank position. Sensor, cleaned mass air flow sensor. Ran 2 bottles of injector cleaner in it. Still missing???? It runs and idles great. Just has a miss in the lower RPM's 1000-2000 then goes away. I really don't wanna take it to a shop. What do you all think??

85 ranger 2.3 fuel injected misses at high acceleration. Fairly new plugs and wires, just replaced the timing belt, pretty new fuel pump in tank, new fuel pressure regulator and pcv. It idles well, starts up and drives pretty well until you get it in 4th and really bog it down. Could be timing issues but I'm pretty sure I did everything right when I put the belt in. What it could be? I know when the tank fuel pump went out, it did something similar for a while...

I've got a 1988 2wd Ranger with a 2.9l v6. I just recently got it running. It has been setting for awhile. I replaced fuel tank, both pumps, fuel filter, Plugs, Wires, Cap, Rotor, TPS. It ran great for about 100 miles. Then yesterday on my way to work about 4 miles down the road it started to miss/stumble especially at about 55mph while in overdrive. When I got home I pulled the codes and I got KOEO 22 Map sensor signal out of voltage(engine off), 53 TPS signal voltage to high, 95 Thermactor Air System Problem, or Fuel Pump Monitor signal, indicates circuit problem.
KOER I got 21 ECT sensor signal voltage out of range or loss of signal during normal operation or Crank Sensor problem, doesn't have a crank sensor I believe. But I did change the ECT sensor and it still stumbles and seems like it misses. Noticed it is sluggish getting up to speed kinda surges and bogs. Im at a loss it isn't showing any more codes. Checked all plug wire connections and made sure everything was making connection. The only other thing I can think of is that the ignition module on back of distributor is going bad. Not advancing the time correctly.
