Ford Ranger / B-Series :: Truck Sputters - Cylinders 2 / 3 And 4 Misfiring - Bank 1 And 2 Running Lean
I have a 99 ford ranger xlt 4.0 ohv basically it sputters so bad while driving it sounds like a dump truck but it all started when I changed my o2 sensors but in doing so I broke my heater control valve and when I was going down the road it started sputtering well it started sputtering so I checked the o2 sensors there good and I changed the heater control valve. But nothing so I changed my coil pack spark plugs and wires but still nothing. But on my reader it says cylinders 2,3, and 4 are misfiring and bank 1 and 2 are running lean plus it has a bad aroma of gas in the engine compartment but when it idles its somewhat smooth but when I'm driving it its horrible the sputtering is so bad it takes awhile to get up to speed plus I'm only getting 100 miles to a whole tank that's like 8 or 9 mpg I need to fix this soon. This is my only transportation...

1993 3.0 V6 5 Spd ... Changed plugs wires Cap and rotor put in a new idle control Valve. No Check engine light. When i am running down the road feels like it surges,hickups, while its at idle the motor shakes like no tomorrow. Just dont want to throw money at something and not be the part that was wrong. Truck has plenty of pickup runs like a raped ape going down the highway. seems when i accelerate the miss clears up and not there. RPM gauge needle has some movement in it. Also put in K&N filter fuel filter as well.
View 6 RepliesFord Ranger / B-Series :: Idle Good Miss / Hesitation When Taking Off And No Power When Accelerating
I have a 85 bronco 2, but i have no luck with responses in Bronco 2 forum, so here goes. It is the 2.8 carb, manual trans with 109K miles. Idles really well some hesitation when taking off but really bad miss and not power under acceleration. KOEO codes are 31 and 84 CM code 18. I have plugged the vacuum line to the EGR and have noticed a dramatic difference. I have tried to rev the engine and check the vac line to the EGR but I do not feel any vacuum, and at idle the vac line on or off doesn't change things. Any recommendations to whether it is the Sensor or the valve itself and what gives with the 18 code. I am hoping to have timing checked by the weekend.
View 2 RepliesFord Ranger / B-Series :: Erratic Shifting And Flashing O/D Light
I have a 2003 Ford Ranger, recently I had the heater core fail. One thing that happened during the heater core starting to leak is the "THEFT" light came on brighter than normal and no longer flashes when the truck is off. Also when the theft light started acting up the O/D OFF light came on and would not shut off. If I pushed the O/D off button the Theft light will go out and then come back on after the button is released.
After the heater core was replaced the lights stayed on as described above. Every once in a while the O/D off light would stay off but then come on later. No really problem besides the lights and O/D off button not working. Now today the O/D off light started flashing and the truck kept shifting in and out of O/D.
I'm leaning towards a speed sensor issue. I'm going to check and see if there is any codes tonight and will post my results. One other thing that happen with the heater core leaking is the "CHECK ENGINE" light came on because the O2 sensor was shorted out. Have the O2 sensor now and plan on replacing it while I trouble shoot the erratic shifting in and out of O/D.

View 1 RepliesFord 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?
Ford Ranger / B-Series :: Random Miss At Full Throttle
2002 Ranger XLT 4WD 4.0.. I was passing another car at about 55 when they also started speeding up (go figure) so I floored it and got on around them but before I lifted I felt it miss, the CEL began flashing so I slowed to the speed limit and went on to work. The light flashed for about a mile then went out. So on the way home I floored it again close to home and the CEL came on again. Got home and put the code reader on it and all it had was a random misfire so I have cleared it. The truck has new plugs, wires, etc for a complete tune-up. I don't usually run at full throttle so don't know if that would be normal for the Ranger, the Ranger was my wife's truck for 12 years and now is my DD. Need to clear this up? Thought of changing the fuel filter in that is still the original one.

Just hoping that there is something common that causes this problem. This thing can idle just as smooth as you could want one to and the next time it will have a dead miss, and the miss is not consistent. It may miss like three hits then be ok a little then miss a little. There is no CE light or codes. Again just hoping there is something common.
View 2 RepliesFord Ranger / B-Series :: Speedometer Dial Started Climbing When Driving On Highway - Erratic Readings
On my '91 last week I was driving on the highway about 60-65 when all of a sudden the speedo dial started climbing to 70-75-80-85 and past. The odometer seems to be working ok? Still when I drive it still operates in the same manner. It never bounces around or falls back. The needle is sort of stable such if I maintain a speed the speedo will maintain even though it's incorrect. There is a slight wavering of the needle meaning it's not as stable as it use to be. With the odometer working I was wondering and don't know. Does the cable drive the needle or is it electrically controlled? I'm thinking of grabbing another instrument cluster it that is the problem, I'd like to know more about it and understand how it works so I don't just throw parts at it until it's fixed.
View 1 RepliesFord Ranger / B-Series :: 1997 4.0L - 0 PSI Compression On 3 Cylinders
I've been fighting some issues with the truck and decided to do a compression test to decide if I want to try to keep 'Old Yeller' alive or not. I'm all for working on it until I have to dig into the lower end of the motor. I rented a compression tool and the results were a little shocking. I did this test with a slightly warm motor, fuel pump relay pulled, all spark plugs pulled and throttle @ 100 %. Motor turned over 10 times for each cylinder. I even moved all the rubber o-rings on the tool up on the threads to make sure I was getting a good seal.
Cyl 1 - 40
Cyl 2 - 0
Cyl 3 - 0
Cyl 4 - 80
Cyl 5 - 0
Cyl 6 - 60
Needless to say I didn't even bother doing this wet. My only real question is can this be close to accurate. I drive the truck daily. 160k mi on it.
I'm fighting the dreadful P0171 and P0174 codes and after a couple cycles I will get misfire codes. Its low on power (hard to keep @ 70MPH with some wind) and gets 10MPG right now. However it starts and runs and stays consistent (even though it rumbles like it has a nice cam in it).
Is it time to put Old Yeller down ? Are these compression results even remotely accurate ?
Ford Ranger / B-Series :: 2001 V6 Only Runs On 2 Or 3 Cylinders
My 2001 V6 Ford Ranger Edge has 124, 000 miles and always ran very well, Shortly after a minimal attempt to pull a vehicle out of a ditch the vehicle began to run poorly. This may be coincidental as problem did not begin straight away. The engine refused to start at first but now appears to run on 2 or 3 cylinders. I have checked AND CONFIRMED the following:
Spark at all cylinders
Fuel filter replaced
Fuel pump checked
Fuel pressure 56 psi at schrader valve on fuel rail
Fuel inertia cut off valve checked
E_Z start sprayed in feed horn did nothing
I hope to avoid towing it to the dealer,as I recently had a very negative experience doing this with the Honda dealer..

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...

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.
Ford Ranger / B-Series :: Getting Good Spark From All Cylinders But Not Starting
I just finished rebuilding my 1990 2.9 and it wouldn't start. When we did the initial start up, the truck needed ether to start and ran decently while stumbling. I found out that the spout connector was removed from the previous owner so I spliced it but still no starting ...
I installed a new fuel filter, fuel pump, cleaned the injectors, spark plugs, spark plug wires, distributor cap, rotor, air filter and cleaned the MAF. ..
Its not a spark problem because I'm getting good spark from all the cylinders and yes the timing was set correctly. It sounds like it wants to start but just doesn't have something to make it boom. There are also no codes...
Ford Ranger / B-Series :: 1999 - Truck Will Miss / Sputter And Buck Randomly
1999 Ranger 4.0. I have an issue with my ranger. Sometimes the truck runs awesome.While driving along the truck will miss and sputter and buck, when this happens, I almost can't maintain my speed. Sometimes when this happens if I put the truck in neutral and shut it off and restart it. The problem will temporarily go away. Occasionally it will go away on its own. When it goes away on its own it's like someone flipped a switch and all power is returned and running smooth. When the truck is at idle it depends on the mood of the truck, sometimes it's fine and other times it wants to die. I got to make this truck last awhile longer.
View 7 RepliesFord Ranger / B-Series :: 1990 V6 3 Cylinders On Driver Side Not Firing
Is there something that would make the 3 cylinders on the drivers side of a 1990 2.9l not fire? I have spark to the plugs and pressure/fuel at the schrader valve on the fuel rail. The passenger side cylinders are firing fine and the engine runs (roughly) on these 3 cylinders. Truck was running just fine, then all of a sudden, drivers side is dead. Is there a fuse or something that controls these three fuel injectors?

Ford Ranger / B-Series :: 2003 - Multiple / Random Cylinders Misfiring
I have a 2003 ford ranger edge with the 3.0l engine. It started acting up today so i brought it to get checked because the check engine light came on. Three codes where pulled p0300, p0306, and p0313. They were multiple/random cylinders misfiring, cylinder 6 misfire, and first misfire at 1000 rpm. I have replaced the plugs and coil and still have the trouble.
