Ford Ranger / B-Series :: 1998 - Missing On One Cylinder During Cold Startup
Feb 12, 2014
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.

I have a 98 Ranger SuperCab XLT 4WD 4.0 Auto. Occasionally, especially when it has been sitting for more than 3 days, it shakes for maybe 30 seconds on startup. It smooths out gradually after that, maybe 15 sec. to normal smoothness. It seems like it is firing on all cylinders and is more like something out of balance.
Never does it when sits less than 2 days. When it happens, the longer it sits the worse it shakes.

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.

I got this 98 Ranger 2.5 that I've done a tune-up on less than 30,000 miles ago. I changed plugs, wires, and both coil packs. Timing belt, thermostat, fuel pump, fuel injectors are all recently changed too within a year or two. Fuel filter and air filter I change every 30,000 miles. The truck runs as great as a 4 Cylinder will run. It's at 344,000 miles but the engine was changed once so it probably has over 100,000 miles on it. There is just a slight miss you can hear through the tailpipe but it's not severe enough to be picked up by the Check Engine Light. In fact, even when the coils were totally gone it never put up the Check Engine Light. I can tell when a coil pack is going out on this because it's done it several times so I usually just change them with the tune-up. It's only a slight miss some people may not even notice it. I was just wondering is there any way to track down where the miss is? I tried looking under the hood in the pitch black and there's no plug arcing.

1998 ranger 4.0L. I ran my scanner on my truck to day and my 2 bank 1 sensors seem to be bouncing between .150 and .700 but my bank 1 sensor 2 seems to be stuck at 680-720 and not bouncing, is this normal?
I did pull a code po135 heater circuit malfunction BANK 1 SENSOR 1 ...
Also I am not sure where my fuel trims should be...
My
ST1 10.0
LT1 25.0
ST2 12.0
LT2 25.0
closed loop.
When I first got the truck I pulled codes for lean bank 1 and 2 also a cylinder #4 misfire and the bank 1 sensor 1 heater circuit. I reset the codes and the heater circuit bank 1 sensor 1 popped the mil light in 5 min. So I am starting with the o2 sensors. I've not found any vacuum leaks at this point.

I 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?

98 ford Ranger 2.5L.
I have not heat from the vents, doesn't get warm at all. If I idle the enginer in 30 Degree weather it gets to almost the C.
Upper Radiator hose is hot, I have verified the thermostat is new and it opens at 192 degrees as it should. Replaced the Water Pump, Fan spins freely.
I have attempted to burp the system, it isn't kicking out anymore air from the lines that I can tell. I used a large funnel and filled it with Anti-freeze, it filled the radiator, burped the system and the reservoir filled to overflowing. All with the engine hot. (To be specific the funnel was always full of fluid so no air could get sucked backwards)
The heater core hose on the left when looking from the front of the vehicle does not get hot, the one on the right gets warm. I theorize that the heater core is clogged up somehow and that is why that left line doesn't get hot. There is no fluid in the cab of the truck from the core.

What would cause my 4x4 high and 4x4 low lights to flash intermediately together on cold mornings while driving? It won't switch into 4x4 when it does this either. When it sits and warms up later in the morning all works as should. It doesn't do it all the time but when it does its annoying not to mention it's sucks when I need 4x4.

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.

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.

I've a 1994 Ranger XLT 4.0L with a missing fuse panel cover. I'm trying to get the horn to work and we've traced the problem to a missing fuse. Unfortunately, there are 3 empty fuse slots and no info on their rating or use. Where I can get the proper info. Truck was a salvage, no ops manuals, and sloppy work putting it together.

Truck spits and sputters when it starts up..and now it does it more often New spark plugs, new fuel pump and filter New mass air flow. I changed fuel octain and that work for a few weeks and back it spits...... It seems that when I put something new in the truck it runs great for a few weeks and then it starts up again...... I can not find a fuel regulator that fits the one that is on the truck now......so I have not replaced it........

My 06 Sonata runs very rough at start up when the car is cold. It appears that it is missing on several cylinders. This last for about 15 seconds and then the car runs fine. What could be causing this problem? No check engine light.

I live in Kansas and was home in Georgia for the last 2 weeks. The truck drove great there after a fuel up started missing and surging at 50 to 70 thought it might have been bad fuel. waited till it was low added Lucas fuel treatment and premium gas still was doing it. no check engine light. went to Advance and fuse for light was blown they checked and was getting mass air flow code. unplugged it and seemed to be better, not perfect but better. plugged it back in and went to do it again. Changed mass air flow night before the drive back to Kansas. Ran well from Savannah to north Georgia then started doing it again the rest of the way home. Going to have advance check code again.

My 2000 Ranger standard 4.0 4x4, started spitting and sputtering the other morning just when i was gone up hills then it would quit doing it. The other evening it got to where it don't idle, missing very bad, and wouldn't even pull itself up a slight grade, and the wife said there was flames and sparks coming out the exhaust. Now it wont even try to start, it just turns over. I put a different coil pack, wires, and plugs, and still nothing. I pulled the gas line off the frame fuel filter and its shooting gas out, and I got gas to the check port on top of the engine.
