Ford Ranger / B-Series :: 1998 - CEL Started Flashing / Idled Rough But More RPMs Smoothed Out
Feb 26, 2014
I have a 98 ranger with 2.5 and 225k mostly trouble free miles. This engine has never used a drop of oil and ran good. In Dec 3 miles from work started running poorly and sounded to knock the more I asked for power. The CEL started flashing I made it to work and it idled rough but more rpms smoothed out. Took it to mechanic says he did a compression check with little or no compression on #1 & #2. #3 & #4 fine must have broke rings. Doesn't seem right to lose 2 cylinders at the same time out of the blue. Could anything else be causing these symptoms or time for a heart transplant? He hasn't opened anything up yet.

I have been having with my ford ranger. I bought this off my nephew bcuz he needed some money and never drove it due to it being a 5speed and he has a kid and a wife and no room. OK the issue I am having is in gear or neutral I can't get the 2.5 motor over 3000rpms in any gear at all. If you rev the engine up or r driving it when it hits between 2900-3000 rpms the motor acts as if it is going to die and looses all power until you let off the gas. I have replaced the following items on the truck. Oh by the way I have a Cam 2 hand held and there are no codes or warning lights. All new parts :
1) new fuel pump
2) fuel filter
3)new timing belt
4)new motor craft platinum plugs
5) new motor craft plug wires
6)new Mass air flow meter
7) clutch,pressure plate & throw out bearing along with new slave(that needed it replaced others since I was there)
8) exhaust tube behind motor(rotted out)
9) new idle control sensor (acts as elect. Choke)
Truck starts up real quick and idles fine, but when truck is cold the rpms @ 2500 does the same as when it is warm @ 3000 rpms. I even took it to the local ford dealer in my town. Youngstown oh @ Fred martin ford. They told me the wires should be replaced and plugs along with mass air flow valve. I called them after replacing it and told them no difference and the service manager told me to bring it in again and they will look again. Service manager told me he has never heard of this type of problem and I went to a local garage mentioned it to the lead mechanic. He said that is why he doesn't like fords they are to common in chronic problems and can't be fix without a lot of guess work. I have a Hanes manual and did everything it recommends to no avail.

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 1998 ranger 4.0 and about a year after getting it the belt started to squeak so far if have replaced the belt, replaced the tensioner, and cleaned and wire brushed all the pulleys to remove glazing. And it still squeaks and its annoying and kinda embarrassing...

Here's my issue: My Ranger has been running like a dream until yesterday.
I took off on a parts run for my sons Ranger. I got to a stop sign and as I stopped, it started missing and barely running. I nursed it back home and checked the flashing CEL. It was giving me a misfire on #3.
Since I had been planning on changing the plugs and wires, I dove in and got it done hoping that was the cause of the misfire.
Started it up, same thing. I went to the next obvious item: coil. Replace it, still running like crap. Gave up for the night.
Today, I thought I would dig in using the tips here on the forum. Did the spray down...no errant spark anywhere. Tested fuel pressure: 65psi no drop in pressure on acceleration.
Started pulling wires off the coil one by one. Four of the wires resulted in running worse. 2 had no effect. #3 and #6. The coil was producing plenty of spark on all 6 ports.
At this point I was sure it had to be 2 bad injectors. Since I couldn't get injectors tonight, I moved them around after cleaning them a bit and tried my wire test again. The problem stayed on the back 2 cylinders!?!
I tested for voltage on the back injector plugs and I am getting voltage. I also used a stethoscope to listen to all of the injectors. The back 2 seem to remain silent. I have also unhooked the battery for 20 minutes to reset the PCM. Still missing and running rough....
Here's a list of what I have done:
Autolite Double Platinum APP5144 plugs. .062 gap
Autolite Pro Series wires #97051
BDW E97P Coil
New air filter
What should I do next? I really don't know where to go next.......

Two days ago, I was driving on a North GA steep, windy, mountain road in my 2002 v6 4.0 Ranger. All of a sudden, i started revving real high (about 4000rpms) and getting no power (20mph). I pulled over immediately and transmission fluid was pouring, by the quart, out of my truck. I didnt get to look exactly where it was coming from, since i backed away once i saw a small flame coming from the leak. i then called a tow truck (assuming it was a seal or a hose break) and had it towed to my house.
I started investigating the possible problems and didn't really see anything noticeable under the truck (not that I was expecting to). So what I did was put three quarts of transmission fluid in the dipstick hole and put in gear to see if I could spot a leak. nothing. then I drove it around the block to get it warmed up and put a little pressure on the transmission by driving up a semi-steep hill to see if that would spark the leak again. still no sign of the a leak.
And finally, when I went to go check the dipstick after my test drive, it read to be above the cross hatched area, hence being overfull. What my next step should be?

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.

1995 ford ranger with 4.0. It idles rough. Replaced MAF TPS fuel pump fuel filter fuel pressure regulator upper o2 sensor. IAC.. still idles rough RPMs drop. It isn't as bad since replacing MAF but still not right. What else is there.. Cleaned out the air intake port it was gummed up. Don't know what else to do?

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 am looking over a 1998 Ford Ranger. Very low miles for its age (67,000) and kept in very good shape. When I took it for a drive, I noted an issue.
- there's a whining sound in first gear and reverse that varies according to the engine RPMs. I thought it might be the power steering pump, as that whined when I turned the wheel.
However, the noise went away when I shifted to the higher gears. Been a while since I drove a stick - my Bug back in 2003, IIRC.
What I might be getting into? I really like this machine, aside from that issue, and I would like to nail the problem down ASAP...

Throwing codes ... p0136, p1131, p1151 acts like it going to just stop then will take off, at a stop light it will sound like it has a large cam in it... It is a 1998 4.0 V6 automatic tranny.

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?

Recently bought a 96 4 cylinder 5speed 2wd ranger. 200xxx miles on it and its former owner had a young guy change spark plugs . Truck ran fine before, but after is when the rough running showed up.
A quick check of the plug wires and there locations looked correct and also tested the wires for spark with a timing light attached to them, checked shows all are firing.
Seems to smooth out a bit when rpm's are raised up, but still acts like not running smooth.
I swapped out plugs. Looks like they haven't been changed in a long time .Some of the straps are burnt and are shorter than they should be, but still runs rough, very little improvement .
Check vacuum lines for leaks/breaks and all looked good. removed line off brake booster and plugged, didn't matter.
It doesn't throw and check engine lights. It does smooth out some as the rpm's rise, but still not smooth .

My 3.0 with 216k miles has developed a rough idle and it progressively got better with new parts and cleanings. On startup it revs up to 2k then back down to 600. If I let it idle for about 8 or so minutes my Check Engine Light starts flashing. If I drive about for a little bit it stops and is just fine.
While the light is flashing I get codes P1000, P0305, P0306, and P0316. Which are OBDII Monitor Testing Not Complete, Misfire detected in Cyl 5, Misfire detected in Cyl 6 and Engine Misfire Detected on Startup (First 1000 Revolutions) respectively. Any other time the truck runs like a dream. Gets 20 city and 29.5 highway.
I cleaned my Mass Air Flow, replaced my Idle Air Control, SeaFoamed throttle body and vacuum lines, brand new coil pack, new wires, new plugs, new fuel filter, I've only ever run 91 octane, Chevron with Techron goes in at every oil change and B12 every other and I just ran 3 bottles of Lucas fuel injector cleaner.

I have a 2006 Ranger XLT 3.0 that is vibrating hard/rough idling, cel is on (solid, not flashing), has trouble accelerating with pedal punched. Will sometimes get a sudden burst when pedal is punched with rpms going up but most of the time no to slow raise of rpms with pedal engaged. Hooked code reader up to it and read ignition coil. Replaced the coil and changed plugs and wires. Truck still not running right. what gives? Is this a fuel pump, cats clogged, cylinder issue?

This has been an ongoing issue for about a month. When I start the engine after it has been sitting and is cold it runs ruff for about a minute then smooths out and runs fine. I pulled a P0304 code (cyl.4 missfire) but I do not get a CEL.
I checked the plugs and they were ok but I changed them and the wires anyway as it just turned 50k and the plugs were original. I could live with a little cold ruff idle but the code throwing bothers me. The truck is a 2000 xlt 4x with auto trans. and 4.0 engine. This is my second 4.0 ranger but I have only had it for about 6 months.

Quick back story I bought a 1999 Ford Ranger It is a 4 cyl with an auto trans the guy said it had some trouble with the tranny (major understatement) he also forgot to mention he cut out the CAT. so running a 4 banger off the header.
When you start the truck it rough idles but you have to hold the gas down til it warms up. You can shift into reverse but it labors the motor and the motor will not up the rpms kinda stays at idle and wants to die no matter how hard you accelerate and you can't move up a slight incline.
When you shift into drive you have to rev the motor to 3 grand an it will catch then move slowly forward. no matter how high the revs go. The fluid levels are a tad above the full level and a bit dark for my liking.
Ok, I used an OBDII scan tool from the parts store and it came up with 3 codes P0351, P0352, P0500. From my internet search the first two seem to be coil related which explains why the motor is running like garbage. The last may or may not have to do with what the tranny is doing.

2002 Ford Ranger edge 3.0 flex ... Truck was running fine and giving me no issues. I woke for work the other day and went to get coffee and truck wouldnt start. I could hear fuel pump running and knew it wasnt that, it was acting flooded. So today I pulled fuse from fuel pump relay, and got it to start. Put the fuse back in and ran to gas station. On the way to the gas station it started running really rough, very low and rough idle, trying to stall out. I noticed it had black smoke coming from exhaust. I got it home, and got it to start barely, and it has the same very low and rough idle, but my oil gauge was going crazy, flickering back and forth all crazy, and the idol is terribly rough and eventually stalls out. Earlier today I did put new spark plugs in it, but not sure that has anything to do with the issue. I also hooked it up to a computer and it isnt throwing any codes.
