Ford Ranger / B-Series :: 2002 - Rough Idle Codes / Cylinder 2 And 3 Misfiring
I have an 02 ranger xlt 3.0, it started having a rough idle, codes say cylinder #2&3 misfiring, changed plugs, wires, coil pack, didn't work, still same code, checked injectors on right side, all 3 had ohm reading of 15.8-16.5, the injectors were clicking like they are supposed to, sprayed carb cleaner around the intake ports, didn't change the idle at all,what else can I check or do? with out tearing the engine apart, unless of course I have to, the truck has been very good to me, it's got 205,000 miles on it, I need it to last at least another year...

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.

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...

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 :: 2002 - Misfiring In Cylinder 1
Had a misfire in cylinder 1 so I put new plugs and wires. Still misfired. Changed fuel injector. Still misfired. Changed ignition coil and misfire on cylinder 1 is gone now cylinder 2 and 3 are misfiring. I double checked wires and they are properly installed.

I've got a 2000 Ford Ranger, manual 4 cyl. When cold, she's been stalling out. It happens very reliably when I come to a stop and put it in neutral (or put the clutch in). Only when she gets warmed up does it stop. Check engine light has been on (for a long time) saying the TPS sensor is out and the 4 cyl. is misfiring. I replaced the TPS sensor and it had no effect on the problem. A friend recommended changing the oxygen sensor.

My ranger just started running very rough. Like misfiring, but I think it may be the fuel pump. It starts and drives...but it surges then drives normal, as if fuel is being fed, then starved, then force fed etc. My father asked if I had trouble starting it and to be honest in the last 6 months it was a little harder to start on several occasions. On a few occasions it required more cranking. But that was only a few times.
I tried putting in a fuel injector cleaner and 93 octane gas but it is still running even rougher now. I changed out the fuel filter under the rail about a year ago (maybe 8000 miles ago at most). My father thinks the fuel pump is shot and he laughed because his went on his expedition and he said it is inside the fuel tank and there is no way to get at it without dropping the tank. Is that true? 2002 ranger xl 4cyl
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.

My 2003 ford ranger 3.0 v6 is having a misfire on start up and it is located in the forth cylinder. Where to start to get rid of this problem. i have already changed all my plugs wires and even the coil pack cleaned out the maf and looked for possible leaks. the car shakes really bad at lights and the check engine light starts to flash. Need diagram of where all the cylinder numbers are at and maybe the firing order?
View 14 RepliesFord Ranger / B-Series :: 1987 - Misfiring - Run Rough - Loss Of Power - Dying
My brother's 87 ford ranger 2.3L truck began to have problems. It would be running great, then start to misfire, run rough, sputter, shake and loose accelleration then die. Then it wouldn't start back up for a long time, sometimes til the next day. Little by little, the truck would drive a shorter and shorter distance between breakdowns. He first tried some minor work himself, (basic tune up) - replaced his rotor, cap, plugs, air filter, fuel filter, but that didn't fix it. He went to one garage (big mistake), who said the fuel pump pressure was fine but said he found a broken wire on the harness grounding out and it needed new ignition module and replaced it. (Cost was $350.00+), Garage promised to honor any additional work nec if it continued to have the same problem, and would be free of charge.
Five more breakdowns later and two more "better quality ignition modules", new battery terminals, and 1 new computer later, this joker did more unauthorized work and demanded another $200+ besides the fact of breaking his orig agreement "free of charge" if any further problems! Needless to say, second garage fixed the truck by replacing the magnetic pickup, part # DU 30-C (an electrical part that goes in the distributor and pulsates a current to operate the timing) (it does something like that) and the truck has been driven approximately 40-60 miles as of today, (3 days later), without breaking down. All the other times when picked up from incompetent garage, it wouldn't go more than 1 - 7 miles before breaking down and each time they didn't fix it.
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...

2001 Ford Ranger 4.0L V6... Okay so I bought my truck last September with 100K on it. Ran perfectly fine. No problems for for the first two months and then it started to misfire when at idle. Check Engine Light came on. Scanned and got a random multiple misfire code. I then changed the plugs and wires. Had to repair the threads for cylinder two. Did all that and it kind of but not really solved the problem. A few weeks later got another check engine light. Cylinder 3 misfire. Changed ignition coil. No better. Shortly thereafter I checked again whilst at work and read misfire on 3 and now 2. Currently replacing the intake manifold o-rings and cleaning out intake.

Besides being spark plugs and wires and/or a bad coil pack, what other things could make it so i have misfires on cylinders 4 and 6? going to replace the plugs and wires later today when they get to my house but i just want to know what other things i could be so I can evaluate the potential repair cost and should the wires for cylinders 4,5, and 6 be under or over the intake manifold? I bought my truck used and they are currently under the manifold i think it would make more sense to have them over personally.
I have a 1997 Ranger 4WD with the 6 cylinder 4.0L engine. I can't remember the codes that it tripped at the moment but i think one might have been the 304 code not sure though.
I tripped the 300,304, and 306 code but don't know about any others i remembered what codes i tripped the other day when i had it scanned
Ford Ranger / B-Series :: 2000 - CEL On - Misfire On Cylinder 5?
OK, got a check engine light today when I fired up the Ranger.
Took it down and got the codes read it have a miss fire on cylinder 5. Picked up some plugs and wires, got to get those E3's out of there, but kind of think that's really not going to fix the problem. So that probably leaves the coil pack or injectors.
So what's the consensus on the best coils to use?
Also, being an 18 wheeler for more years than I care to remember, I've learned swapping just 1 injector is never the way to go. So whats the best type of injectors to get and where the best place to get them should it come to that?
Oh, it's a 2000 3.0L Flex fuel 5 speed.
Ford Ranger / B-Series :: 2000 - CEL On / Cylinder 4 Misfire

View 3 RepliesFord Ranger / B-Series :: 2000 4.0L - Cylinder 4 Misfire Sometimes
I have a misfire mystery going on in my girlfriends 00 ranger. What is going on, is there is an intermittent misfire on #4. I have an ultra gauge hooked to it, so most of the time when it does it, it will flash a pending code. A lot of the time, the pending code will go away, but sometimes it will set the PO304 code.
First I tried a tune up. New plugs and wires, air cleaner, cleaned out the throttle body. This cured it, for a short while. Then we were back to the pending code / setting code for #4.
When I pull the plug on #4 it is sometimes wet with gas. If you put a new plug in it runs fine for a while. In fact the last time we took a several 100 mile trip with it right after plug change, and it ran great. The pulled plugs re always in good condition with no burn, oil, chips or glazing. I have been using the standard autolites that are in advance auto's computer for that engine. No issues with the other 5 so I figure they re good enough.
The day after we came back I get the call... Honey its doing it again. Often to the point of having no power at all.
But it will clear itself usually, if not a new plug for #4 will cure it immediately.
So I thought something is killing this plug.... Or flooding it. SO I ran 2 cans of sea foam though it, put in a new plug and an new wire. It fixed it for a week then it did it again.
Ok I think... maybe the coil pack is bad either killing the plug or just not firing it at all? So since the pack has never been change in its nearly 300K life (to my knowledge, shes had the truck since about 60K) What the heck.... a new coil pack for the old thing.
I have not had the chance to clean the MAF but we are talking misfire on one cylinder, every now and then with no real conditions that set it off. More often than not its a pending code that you can even hear or feel and other times its a full blown miss that drags the truck down. Well for a short while until it clears up or I replace the plug.
3 cans of seafoam surely would have cleared a sticky injector. I realize it could be a bad wire to that injector but I have not had the time to tear the fiddle bits off to get to it to clean and test it... or just replace it.
Honestly Ive had a lot of cars and trucks, I don't remember ever having to replace an injector. Ive had bad wires to them but they misbehave ALL the time. This problem is so intermittent its freaky.
She says it does it mostly when its cold or not totally warmed up. Almost always, by the time the engine is hot it goes away.
And hot for this truck is over 185F, which I think its too cold to be running and the thermostat needs changed BUT she thinks cool=good. I keep telling her no, cool is often not good, the engine needs to be up to the operating temp.... which to me means 190-200. Her ranger runs between 170-180 all the time. I doubt thats causing the problem but still.... I think new thermo is in order.
My thinking is since it runs so cool all the time, the issue might be related to a spike in the temp over 180 ish, that gods forbid is opening a crack somewhere to suck air or lose compression.
And a compression test is my next step on #4 if/when it does it again. Now I have had cracked valves before, I don't recall them acting this way. After all sometimes the thing will go 100s of miles under different driving conditions and run fine. I don't think a cracked valve would be that nice.
Shes getting @18 MPG mixed driving, when it runs t runs like a bear. It always fires right up. There is no smoke, white or black. There is no water in the oil, no oil in the water. No audible exhaust leaks. No ticks knocks or oddball noises. For its age and miles almost 300K it runs perfectly.
Well until it has its intermittent issue with the misfire, that isnt bad enough to actually set the code.
Ford Ranger / B-Series :: 1992 - Wheel Cylinder Blowing Out?
'92 Ranger 2WD with 4 cyl and 9" brakes, right rear wheel cylinder keeps blowing out, replaced it twice. I've thought about maybe an obstruction in the left brake line creating too much pressure, or in the junction block on the rear axle. I believe only one line leads to there from the master cylinder, so what else could it be? Only other thing I can think of is that the right brake has a mechanical problem which is causing the forward shoe to move too far away from the cylinder, leaving no 'stop' so the piston just slides right out of the cylinder. But I can't figure that. Original adjuster star wheel was chewed up so I swapped in another, doubt it's that.

I figured something out on my ranger that has been bugging me for a while it was a third cly misfire so I changed the plugs and it went away for a while.the po told me he had just changed the plug wires so i didn't mess with those and it was an intermittent misfire so i changed the brain box because it was 15.00 at pull and save and it had been all updated boy did it run smooth for a while then the misfire came back. So I decided to check the 3rd cylinder plug wires and found out the one that is hard to change on the drivers side was badly rusted so i borrowed one off my windstar it was a little longer but boy does it run smoother and it doesn't die all the time and chug chug all the time now i just need to change the battery. i have already changed the clutch and the tranny twice i took one out of an 88 and it fit just fine by the way the engine is a 2.3 8 plug engine with over 230,000miles on it my next project is a timing belt and a heater core won't that be fun and yes i smell the antifreeze inside and don't like the stop leak like the last person put in.
View 2 RepliesFord Ranger / B-Series :: 2006 XLT V6 - CEL Flashing - Cylinder 2 And 3 Misfire
Been awhile since I've been able to post but I've got a serious issue with my 2006 Ranger XLT 4L V6. So last night about 2 miles from home my check engine light started flashing like it was a at a rave and my engine wasn't acting right, also had the STRONG odor of raw gas, no other lights from the dash, no fluids leaking, oil was good n nothing in radiator but coolant. Was able to baby it to my current home but all my tools are in storage so had to wait to get my ODB scanner to see what's up. Scan came back as 'cylinder #3 misfire' & 'O2 sensor reading rich'.
Go cylinder #3 spark plug out and it were fouled bad. Got ride to the store and got a whole new set. Got back n got'em changed and fired ut up, idle still rough and check engine started flashing again and white cloud coming from exhaust pipe and STRONG odor of gas. Check and now have 'multiple missfire', 'cylinder #2 misfire' and 'cylinder #3 misfire'.
Shut it down go and double check ALL spark plug wires are connected and TRY to start, get about a turn n a half then starter spin. Try again and the engine won't even turn over. "Great I've seized the engine!" Was able to put a socket on the crankshaft pully and manually turn the engine over "whew didn't seize the engine", did this a couple of times and tried to start, was rough but eventually it fired up, still idling rough and again check engine light flashing, while it was running I pulled one plug wire at a time from the coilpack to see/feel the lighting and there was spark for the 3 I pulled, didn't affect engine idle.
Run codes and 'cylinder #3 misfire', so now that the engine is was warmed up I pulled out my ohm meter and started checking wire resistance. Cylinders #1, #2 were at .012, #3 was .011 and #5 was .009.
I've figured that the raw gas is due to cylinder #3 not burning and just pushing gas into the exhaust. So to the brass tacks, do I invest in a new set of wires? Or could it be the injector being stuck open and just flooding the cylinder? No when I originally pulled the #3 plug fuel did not spill out. Haven't pulled #3 again due to it being May in Arizona and had to take a break. I'm going on the assumption that the engine wouldn't start after a short run do to "hydraulic lock in cylinder #3", my manually turning the engine over cleared this and allowed the engine to start.
