Ford Ranger / B-Series :: 1999 - Running Rough / Missing And Surging At 50 To 70?

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.

Ford Ranger / B-Series :: 1998 - Rough Idle At Cold?

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?

Ford Ranger / B-Series :: 1998 - CEL Started Flashing / Idled Rough But More RPMs Smoothed Out

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.

Ford Ranger / B-Series :: 1998 4.0L Manual Won't Shift As Soon As Start The Engine

I'm 1200 miles from home living in a hotel right now. Was on my way to the store this morning and I took it out of gear. When to put it back in, and it wouldn't go in. Fortunately, I was still moving, so I coasted off into a parking lot. Once I shut the engine off, it went right into gear. It moves freely through them all. As soon as I start the engine, it won't shift. It is not my clutch. I can start the engine with it in gear and the clutch in, and it won't creep at all (was sitting on level ground when I tried). At least this means I can get it places if I slip the clutch a lot. Took the inspection cover off, and all looks well in there. It hasn't been acting strange. It shifted just fine right up until this. No strange noises either until now.

Now there is a slight squeaking sound if I try to force it into gear with our without the clutch pushed in. Since I've never let a mechanic touch my baby before, and I have to now, what possible things should I be looking for to make sure they are honest? I'm thinking maybe I killed my pilot bearing? Second, while its apart, I'm going to have them replace the clutch and slave cylinder since its got 160K on it and as far as I know, the previous owners never did that. Recommendations on what clutch to get? Its been towing some lately. I don't know if that makes a difference.

Ford Ranger / B-Series :: Surging Idle When Start It Up

My son bout his first truck yesterday. 98 ranger sc 4x4 auto 4.0. Beautiful shape 139000 miles. got it cheap as it has issues. its been parked for a year. It has a surging idle when you start it up. rev it to 2500-3000 rpm and it idles fine turn it off and restart it surges again until you rev it. When we test drove it it ran like it was running out of gas/bad fuel pump, sputter at full throttle but accelerate at part throttle. Gauge said under 1/4 tank of gas. We put 3 gallons of gas in it when we got home and it seems to run fine now other than the idle surge. it had a 174 code(lean bank) but if it was running out of gas it should pull a lean code right? I am thinking IAC or intake leak.

Ford Ranger / B-Series :: 1998 - Engine Noise / Sound Coming From The Lifters

I have a 1998 ranger 2.5L engine. I took it to a Ford garage and they told me I have a rod knock..........I took it also to a good mechanic and he said the sound is coming from the lifters.

There is 172000 miles on motor and the noise started at 131000, and is getting worse. Should I drive it till it blows, or is there a way to tell what the problem is?

Ford Ranger / B-Series :: 1994 3.0 4x4 - No Start / Surging Idle When Hot?

I'm having trouble with my ford ranger. It cold starts fine, and drives fine while cold. Once it warms up the idle is barely keeping it running, or surging 1000-1500 rpms above normal idle. Any gas I apply while hot idling will stall out the motor, and will not restart. It acts like it is very flooded when I try to do a hot start. I pulled the IAC valve off and cleaned it even though it was very clean and actuated properly. I also cleaned my MAF, and that changed nothing. I really do not want to just throw parts at it hoping I guess right before I'm broke. Not sure where to go from here, and I live in Alaska where I am fixing this outside.

Ford Ranger / B-Series :: 1998 - Weird Idle At Stops - No Check Engine Lights

I’ve got a 1998 Ranger with 166,000 miles and it’s starting this weird idle at stops where the engine drops about 150 RPM’s and then fluctuates. The problem is intermittent and no pattern as to cold or warm engine. I changed the plugs and wires at 100,000 and the plugs again at 150,000, so the wires have 66,000 and the plugs 16,000. I really don't want to shotgun the plugs, wires and coil pack. I understand that vacuum might have something to do with my problem?

Ford Ranger / B-Series :: 1998 - Engine Stall Just For A Second Making Truck Buck As It Accelerates

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?

Ford Ranger / B-Series :: 1998 - Whining Sound In First Gear And Reverse That Varies According To Engine RPMs

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...

Ford Ranger / B-Series :: Runs Rough For About A Minute After Engine Started When Cold

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.

Ford Ranger / B-Series :: 1999 - Stalls / Rough Idle And Engine Dies

I have a 1999 B4000 4.0L with 160K miles on it. Bought the truck new. Up until about a year ago it ran perfect but has developed an idle, stalling and occassional jerky ride problem. It occurs at any temperature, engine hot or cold, A/C clutch on or off and in Park, Drive or Neutral. When you start the engine it will not idle unless you keep your foot on the gas. The idle speed will drop to 200-300 rpm and the engine dies. Sometimes you can barely tap the gas pedal and the rpm will shoot up to normal idle speed (about 900 rpm) and stay there a few seconds then begin to drop again. If the engine is cold it will often die a couple times after starting even with the foot on the gas and then about the 2nd or 3rd time run with your foot on the gas.

At stop signs and red lights you have to keep your foot on the gas to keep it running. If you are approaching a stop sign and take your foot off the gas to coast to a stop and brake, the engine rpm will drop and the engine will die. It always starts fine though. Once you are driving it generally runs just fine at low or high speed. You can generally set the cruise control on the expressway and cruise right on. However, sometimes all of a sudden the truck will start bucking and jumping as if it has a terrible misfire. It usually lasts a few seconds and quits. Often if you step on the gas it quits. Even less occasionally the engine will begin to slow as if it is starved for fuel and slow down. You can press the pedal to the floor and it sputters a bit then picks up and runs fine.

I have read about all the threads in this forum and others and tried some of the suggested fixes but it still has the problem. I have tuned it up with new plugs, wires, fuel filter, air filter and PCV valve. Based on some of the forums advice I have replaced the IAC valve, the EGR valve and EGR Pressure Feedback Sensor, and cleaned and inspected the MAF sensor with MAF cleaner. I have checked all my vacuum lines and no leaks there and checked the engine timing which is fine. Fuel rail pressure and engine compression are also fine. Spark plugs show no clues, exhaust is clean and the engine uses virtually no oil. There has been no tear down on the engine like removing the heads, cam, timing gears or any of that and the engine is completely stock.

It shows no codes related to the problem. Two or three months after the problem started I showed a code that indicated an injector problem, traced the problem to a bad injector, replaced the faulty injector and it was fine. That took care of that code but didn't solve the idle problem. In my younger days I was into drag racing and I rebuilt engines, swapped transmissions, etc. and still do my own tune-ups today so I am fairly familiar with auto repair and have most of the tools for testing newer cars but this one stumps me. As a last resort I'm about to take it to the dealer.

Ford Ranger / B-Series :: Rough Idle - Check Engine Light Starts Flashing

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.

Ford Ranger / B-Series :: 2003 3.0 - Misfire On Cylinder Six / Running Rough And Check Engine Light On

I have a 2003 ranger and have had ongoing problems with misfire cylinder six and have had three different mechanics diagnose the problem as a bad ground. I have replaced all plugs, wires, coil pack, injectors and am constantly pulling the plug on cylinder six, cleaning and often replacing, I also disconnect the battery so it resets the check engine light and it runs fine for about 100 miles and starts running rough again and on goes the check engine light. I have 134000 miles and have maintained it since new.....

Ford Ranger / B-Series :: 1998 - 4.0 OHV Miss Under Load

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?
