Ford Ranger / B-Series :: 1998 Won't Go Over 3000 RPMs
Nov 9, 2010
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.

After I got done with all of this crap on my Ranger, I noticed that it was driving great! But...today I was on my way to school and BAM! My engine idle started hitting (presumably because I do not have a tachometer) about 3000RPM and lowering down to about 2500RPM and from there, every time I am not in gear it decided to fluctuate between 2500RPM and 3000RPM. Crazy style too.
Now, I got to school, and getting closer to it at a stop light the truck basically died. It was almost at 100'ish RPM. I gave it gas, and BAM. I hear a continuous hissing noise from under my hood. Haven't diagnosed it fully yet because I just got home and its 12AM.
Now, every time I stop at a light or in traffic or whatever it may be, I have to give it gas every other second, like a small push on the pedal, to make sure the truck doesn't die. Also, every time I am out of gear and my RPM's are at an 'idle' state, I get continuous hissing from somewhere, I get no power loss or anything, just really weird idle RPM's and hissing when my foot is not on the gas basically. It is strange. I think It is some sort of Vacuum leak but I am not sure.
To get a better picture of the 'hissing' noise, it is the same hissing as you would hear when letting the air out of a tire. That is the best way I could describe it.

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 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...

I own a Ford Ranger 2003, 5spd 6 cyl. My problem is when I'm driving and the engine is revving above 3000 rom's. It begins to sputter and buck as if the engine is running out of gas. It only lasts a few seconds. It ends as quickly as it starts. It does not occur each time when driving above 3000 rpms. My mechanic took the truck for a test ride and of course he could not find anything wrong. His advise was to wait until it got worse. I would rather solve the problem now. It is difficult and dangerous when trying to pass vehicles on the road.

Driving a 2008 Ranger XLT 3.0. Starts runs and drives fine, how ever it seems to have a tinny ruff idle.
What I noticed is when in park or neutral when I idle it up @ 3000 RPMs it seems like it runs on 3 cylinders and sort of cuts in and out very quickly. Is this a protection thing on the ranger.
Running on the road it kicks down and runs thru all the gears normally from idle all the way up to 5000 RPMs. Just would like to make sure this is normal.

Ranger often wants to idle at 2,500 to 3,000 rpm. I'm glad its got a clutch! This is a long term intermittent problem that is getting worse. I have replaced the the IAC twice. I have unplugged the IAC when the engine is in high idle and the engine idles normally. But, starting the car with the IAC unplugged makes car run rough. That makes me think the IAC is not getting the right voltage input from the pmc (eec). Mine is a 2002 with the 3.0 engine. Throttle plate seems to be closed.
What sense inputs does PMC use to determine idle air position? Also replaced TPS sometime ago but that didn't work either. Sometimes turning off the a/c will knock the idle back to normal but not always. Turning the car off completely usually resets idle. But the high idle comes right back after accelerating. Drove the car today and idle would stick and stay high when clutch pushed in coming to a light. However. as the car slowed to a stop the idle would come down when rolling 1-2 mph. ??

So that's what if feels like, in park at idle it sounds great, starts great no codes. IF you floor it it will not go over 3000 rpms in park, it feels like it has hit a rev limiter. I have 60psi fuel pressure at idle and at 3000 rpm.
When driving down the road I won't go over 55 mph and drives normal if you keep it under 3000 rpm, if you give it more gas it falls on its face?
AC is not working (clutch not engaging)I don't know if that's related or not.
We did just swap the motor the truck is a 2003 2wd drive. motor came out of an 2002 4wd. we are running the 2wd harness, computer egr delete etc.

I have a 96 ranger with the l4. Right before I bought my newish truck last December, it's started miss firing and running really bad. I replaced the spark plug wires, most of the spark plugs, and both coil packs. Didn't work at all. Then I bought my new truck and parked. Fast forward to now. Fired it up, ran REALLY bad. We changed the wiring order from the 96 order to the 99 order.
But the truck idles from 500rpm (barely running) and randomly jumps up to 2-3000rpm and then back down. Driving it has NO power, rev it and it stays at 2-3000 for quite awhile. Sometimes it randomly dies. REALLY need to get it running quick and cheap. Getting ready to sell my daily driver to find something else and I need something to drive while I hunt for another truck.

My sons 1998 ranger is in mph. Converting on to a kmh dash. There's one at the wreckers and I was wondering is it a direct replacement or is it a computer swap also? What years would work?

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?

2001 M B3000 v6 my sons truck w 122k. He is overseas and I took it to deliver a CB750 bike to my brother in law... 4oo miles away from my place.
In the middle of nowhere TX it developed a bad miss or knock, almost a shudder in the 2 to 3 k rpm range. Idles ok just below 1k runs fine at 70 mph as long as the rpm is near or over 3k.
Not sure I want to turn around and drive back the 400 with it running like crap. I will take it to Autozone and pull codes tomorrow a.m. but what should I expect?

At the beginning December I put my brand new winter tires (general altimax arctics) on the factory steelies and put them on the car gearing up for the snow. Not to long after the install I notice that I was getting a very strong engine vibration starting at 3,000 rpms and it stopped around 3,100 rpms no matter what gear I was in. At first I though it maybe just the cold affecting the engine. Well...
Last week I put my summer rims and tires back on for the 1,600 mile trip to MO and back, and like magic, no more heavy vibrations. Smooth acceleration throughout the normal driving rpm range. I just changed the oil and tranny fluids Tuesday after we got back and with the warmer weather the car is running smooth as silk. Still an awesome car with awesome mileage and couldn't be happier.

I have a 1998 ford ranger and it will not disengage out of 3 gear. The truck still starts but if you let of the cutch. Of course, It stalls. I'm doing the work myself but where I should start looking.

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?

I've got 30 lbs of fuel pressure that drops to 28 if you rev it up a bit on a 1998 ranger 4.0 with a new fuel filter. Haynes manual say it should be 56-72 lbs. Bad news is fuel pressure regulator is in the tanks with the pump. Can the regulator be swapped out or is it one assembly with the fuel pump? Is there anything I should check first?

Ok so my dad has been using my 98 while I was fixing his 92 4.0. I had the 92 perfect and then someone pulled in front of me and totaled it out. Well now I got my 98 back and it's all messed up. Check engine is on p0171. Fuel pressure test done and it's steady 40-42 psi. I remember last year I checked it was like 68-72 psi. It hasn't been a year or two since fuel pump and strainer were replaced. Filter probably 15,000 miles ago. It's currently running good sometimes it cuts off when you start it then next time it stays running. Is this another fuel pump failure? How much longer will it last on 40 psi? The fuel lines and tank have 336,000 miles, engine maybe 150,000 and injectors have about 20,000 miles on them.

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.

so heres whats happening. My 98 ranger speedometer has not been working since I owned it (I am the second owner who got it from a grandpa) and I've replaced the vss sensor two times, got a new connector and gave that a try and still nothing. Yes I've looked for cracks in the wire or any exposed copper, I've looked through many forums and cant figure it out. At first before replacing the vss, my abs and check engine light weren't lit up until i put a new vss sensor on that i got from o'reillys, so then i got another one thinking it was just a bad sensor and still no luck. another thing is when its cold in the morning and i get in my pickup to go to work it will start working once i go over 30 and fluctuate between that and 20 but if i don't accelerate it will not bounce all over the place.

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.
