Ford Ranger / B-Series :: Losing Full Power Like Cutting Out While Under Acceleration - Code P1443
Oct 9, 2015
97 ranger 2.3l ... I have a problem where I'm losing full power (like cutting out) while under acceleration it's only for a split second almost like a hesitation. I got p1443 for the first time today and I was looking at my fuel trims and I noticed my long term FT is at 99.2% and never changes while my short term goes between negative and positive no more than 6%positive and like -4% I assume this is normal for short term but I really am just guessing on that. I am thinking perhaps I need a new fuel pump...but maybe I'm wrong...truck has a new fuel filter and a new evap purge solenoid...

I've been getting this code for a while. Changed the Purge solenoid and valve, replaced the hose from the canister to the two units, didn't change the hose to the intake.
Is there anything else to check? Could it be a bad gas cap? the one on the truck is a replacement.

I have a 1997 Ford Ranger and my Check Engine Light came on a while back. So I eventually bought a scan tool and I'm only getting one code which is P1443. I've looked at both my Chilton and Haynes Manuals, my Ranger manual itself which is pretty useless for this problem, and I've been searching the internet like crazy.
From the threads I have read here it doesn't seem like a hard problem to fix yourself, and it seems like if you take it in anywhere they will charge you an arm and a leg to work on the EVAP system but it's an affordable do it yourself project.
I just don't know where to begin though, I see people talking about buying the complete set with hoses and the canister and sensor all together but I can't find all these parts. Where do I begin to repair the EVAP system?

I have 92 ranger with 3.0 v6 in it.
It flashes out code 212 ive replaced the ICM and checked the spout connector for corrosion but it still flashes out 212 and has a rough idle no power on acceleration condition.
also when the idle starts acting up the check engine light stays real dim and if you rev it it will get brighter

I recently picked up a 93 ranger sport 4x4 with 2.3L engine and 5spd.. Has run fine for the first 2 weeks of ownership but yesterday morning, it started cutting out on the highway. When I say cutting it is like all loss of power for a brief instant and then it right back without even losing any speed, I could watch tach drop from 2500 to 2k and then right back to 2500 again..
Did it sporadically all the way home about 10 miles sometimes once in a mile other times 6-7 times in a mile. Truck has 126k on it, and within last 26k miles PO replaced timing belt, coil packs, plugs, wires, ICM, and just before i picked it up from him a new EGR and fuel filter.
No check engine light
Fast forward to this AM
Wouldn't start at all, i can hear fuel pump spinning and she cranks and cranks but no start up.... played with multiple things including the ICM but found 2 of 3 heads rounded off so i cant remove it until i can get it in to my garage and dremel those suckers off..
Went and bought a replacement ICM figured i could plug it in run a ground from the bottom left hand bolt hole so i could get it fired up and in to my garage.. plugged the new one in grounded it and it still wouldn't start...
So I decided to replug the original ICM back in and grab my spark plug tester, remove number 3 plug wire on passengers side insert the tester and have my wife crank it over and wonder of wonder it fires up...
shut it down remove the tester and have her start it up again and it fires right back up so i let it warm up for 15 minutes.. grab my autoxray.. shut it down hook up the scan tool and run the KOEO scan.. gives me a passed 111 code... OK lets start it back up and run the KOER test.. wont start back up.. reinstall the spark plug tester to #3 wire and NOW it has no spark..

Ok I've got this 98 Ranger with the 2.5L and the 4r44e automatic. The engine is used and has about 100,000 miles now and is it a good state of tune - so I think. The transmission was a remanufactured I bought a few years ago that was built with the shift improver kit, Kevlar bands, extra planetaries, 4wd pan, and external cooler. It's now got 92,000 miles on it and it's been serviced every 30,000 with a fresh 4wd filter and Mercon V fluid. It's outlasted the last 3 transmission I've had in my Ranger. I've got 315,000 miles on the body. For awhile it was randomly losing power while driving like it wouldn't shift, almost like it dropped a couple cylinders, then as you kept your foot on the gas it would recover and rev up and shift.
Then sometimes randomly at stoplights it would shake at a stop and have no power at take off until it hits 30-40 mph. Sounds like a converter, is what I thought. But now it's doing it more often but not the shaking at stoplights as much as randomly losing power while driving normal speeds. Last night I drove it about 50 miles after doing a fresh filter and fluid change and this time it did it so much it threw a code up P1131. Even though that's a O2 sensor code, could it be hidden by a transmission valve body problem? One transmission shop said it could be a valve hanging up just by me describing it to him. Could this be ignition or fuel related or is it all tied in with the transmission problem, if it is even a transmission problem?

I have a 1987 Ranger 2wd, 2.9, 5sp that feels like it is cutting out when accelerating. The only code in the computer (KOEO) is 67, which according to the manual is neutral drive switch (NDS) circuit open. What to look for? Can the neutral drive switch be the problem?

02 Ranger with 3.0 Flex motor, 375K+ miles. Been chasing an issue for a while now, but am about at the end of my diagnosing capabilities. Issue started with a misfire on 5 and rough running engine with no codes showing up. Now the motor is getting worse.
Idle a little rough and no power when accelerating hard. The engine sounds like a popcorn popper under hard acceleration. Motor revs up to 4K but does not pull or shift gears until I let off the gas.
The code that initially showed up indicated a bad Camshaft Position Sensor. Changed that and the Sync assembly - as per instrucions, exactly positioned same as old one. New codes showed up - P1152, P0175, P0171. Cleaned the MAF, rail fuel pressure OK, can't find any vacuum leaks, replaced both upstream ox sensors, and changed #5 ,6 injectors.
Motor still runs the same - like crap, like a corn popper on acceleration, smooths out if only slightly accelerating, but stumbles n bumps on steady cruise speed over/around 60 mph - and no codes showing at present.
I really, really don't want, nor can I afford, to take it to the dealership, but I may be forced to if I can't figure this out sometime quite soon. I make my living with this truck so, no truck, no work till this issue is solved.

finally found the reasons for the two Codes in my '97 4.0.
here are the culprits: Code P401 DPFE Sensor, found it on eBay. (The metal case sensor, nos)
Code P1443 Evap system Purge Sensor (also eBay)
Finally, CEL is off after replacing both sensors above.
Now I have to figure out the REAR ABS light, still ON.

When I'm driving it starts to cutout (but it never dies) and it won't stop cutting out until I floor it and then it's fine for a little bit and it starts doing it again.

1987 ranger 2.9l 4wd 5 SPD ... I just replaced plugs wires distributer cap and rotor and pcv valve and hose. It drives fine for about 3 minutes and then it looses all power and I can't get out of 2nd gear. It idles fine all day long. The guy I bought it from said he put a new tank and pump on it.

Gas gauge went from about 1/4 to full in about 3 seconds and hasn't moved since. 2000 B3000 Mazda 3.0 V-6 auto. I've checked all the instrument cluster fuses (11,26,33). I know of the method of disconnecting the connector at the gas tank to see if its the sending unit or the gauge but I can't see or feel in there good enough to do that. Would either one go bad that quickly? Doesn't seem likely to me.
I've read about a "slosh sensor" in a post on this forum - does my truck even have that? I've had an intermittent wiper problem a couple of times but the multifunction switch wouldn't be involved would it? I'm just trying to see if there might be a simple fix before I add it to my repair list when I take it to have the ball joints replaced.

1999 3.0. Been losing coolant internally. No water in the oil. Been back and forth on doing a full engine swap (its got 250k on it). So finally decided to just try the head gaskets. Anything out of the ordinary on these? Anything to look out for? Any special tools?

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.

Ok I've been plagued with this very random misfire/power loss/hesitation problem going on a couple of months. You could drive the truck anywhere from 50-300 miles without having an encounter of this problem. It seems to do it now mostly on contiguous long trips over like 30 miles. It one time threw up a P1131 code which quickly went away on it's own. This is a list of stuff that has been recently changed: plugs, wires, coil packs, air filter, pcv valve, fuel injectors, tps, idle air valve, MAF cleaned, fuel filter, and egr valve.
I sprayed with brake cleaner for vacuum leaks around the intake tonight after driving a continuous 50 mile round trip it messed a few times on the way back. When I sprayed the EGR valve mounting area it idled rough when it was hit with brake clean and idled up. So there's a leak there. Or is it stuck? It will be driving normal and usually when you come to a stop the engine will start missing really bad and then when you take off there's no power at all. You keep your foot on the gas and eventually it will feel like all the power is just turned on.
If it does it while you're driving highway speeds it will feel like you've lost a cylinder but it's not as dramatic as when you come to a stop and it starts missing. I can't be 100% but I don't think the EGR wasn't leaking before I replaced it and it was still doing the same thing. I'm wondering why the Check Engine Light won't pick up an obvious misfire when you can you actually feel it. And why if it was the vacuum leak would it only start doing it after many miles of driving?

So among the other annoyances my 92 Ranger 4.0 auto has it has a hesitation before it starts spinning the tires under full throttle from a dead stop. It's the 4.0 automatic. I thought it would have more power than it actually does being use to a 2.5 auto. But this 92 4.0 runs and drives good. I've gotten it tuned up with new motorcraft wires, plugs, new coil, fuel filter, fuel pump assembly, fuel pressure regulator, air filter, idle air valve, new O2 sensor, new Dynomax muffler. I can't find any vacuum leaks. The engine idles slightly rough after you start it up from it sitting for a few hours, but quickly smooths out as soon as you start driving it.
This one here has no EGR. Transmission feels good, may have even been replaced by previous owner before we got it. It shifts good and the fluid is clean and the transmission is the cleanest part under the whole truck. No way of knowing for sure. The truck currently has 111,000 miles and I did all that stuff when we got it at 101,000 miles. So what could it be? I'm thinking a lazy injector or could it be the catalytic converter? Or could it be the throttle body? I know I once had a BBK throttle body on it and it made the world of difference in off the line power but it kept throwing too rich/lean condition and a TPS code so I had to return it. It sucks because it did wake up the motor. I returned it and since then the Check Engine Light hasn't come back on.
