Ford Ranger / B-Series :: 1995 - Bucks Sometimes When Warmed Up
Jan 5, 2014
I have a 95 Ranger that when warmed up completely will buck when I let off of the gas. It is a 5 speed and this problem really only happens in 3rd gear and also have noticed it doesn't happen in 4WD. When the engine is cold and I am driving and let off the gas, the truck coasts smooth as silk and as it warms up, there becomes a louder thump when the gas is let off.
It will not do it all the time and it really only happens in third gear at low RPM's coming to a stop. I can give it gas and it picks right back up normally, so I doubt it is a misfire. Also since the truck is a 95 I do not have any CEL indicators, nor is there even a CEL light built into the dash in the truck. It isn't a huge issue because I am used to it and can drive it accordingly without having a problem.

My '90 Ranger is experiencing a pretty bad misfire after doing a tune-up. I changed the plugs (gapped to .045), wires, distibutor cap, rotor button, air filter, fuel filter, and cleaned the IAC. It had a barely noticeable miss before the tune up, that's why I did it. Now, it's pretty horrible.
At idle, it's definitely noticeable, and at cruising speeds (RPM's below 3K) it bucks and surges. The weird part about it is WOT runs are as smooth and (somewhat) powerful as ever! At idle in neutral it will revv up just fine without any hesitation as well.
First thing I did was check the firing order, again and again. Made sure all my wires were properly seated on the plugs and on the distributor prongs. Pulled the plugs back out, they were all clean and properly gapped. I pulled the wires off one by one to try to isolate the misfire, but every plug wire I removed made around the same impact on the motor.
Next I ran codes. KOEO, I got code 95 - fuel pump secondary circuit failure. Don't know what to do about this. Fuel pumps comes on at the turn of the key, relay clicks... KOER, I got 11 (pass code), so nothing there.
Then I hooked a fuel pressure gauge to the schrader valve on the fuel rail, and at idle pressure was a steady 35 PSI. I also removed the vac. line to the FPR while running to see if gas came out. I checked for vac. leaks as well.
Now not sure what to check now. I've checked everything I know to check, but nothing works....

Ok, I replaced the head gaskets on this truck a couple years back and now I am having symptoms similar to the ones I was having then. I am not entirely convinced that this is what is wrong however.
Symptoms:
Truck was idling rough until it warmed up
Truck takes forever to warm up or simply does not warm up
If/when it warms up it operates at higher than normal temp/almost overheats(it hasn't overheated yet)
Heater blows very cold air
White smoke(has been cold outside so not sure if due to temp or coolant)
Overflow bubbled when I shut the truck off, but it has only happened once so far
I am kind of at a loss, but like I said am suspicious of the head gaskets.

I have a 1987 ranger 2.9 V6. Have a intermittent miss @ idle when warmed up. What is the proper way to pull the codes from the computer, i,st something about counting flashes or lights...

My ranger has always run pretty good except for a small bit of chattering at startup which quickly went away after it warmed up. Now all of a sudden its much louder and doesnt seem to go away while driving. I read about the oil pickup tube getting blocked and not properly delivering oil and so I performed the superhuman task of dropping the oil pan to check. While I couldnt get the oil pan all the way out, I got it to where I could feel the oil pick up screen and everything seems okay. I have the valve cover off. Are the lifters adjustable? Whats the issue?

'86 Ranger, 2.3L, Automatic transmission.
Been having a sputtering/rough running situation once warmed up, replaced every so often with open loop smooth running. Lately, have had several occasions where the truck stalls and will not restart after a hard right turn (fuel pump powers up, tho) After 30 or so minutes of repose, truck will restart and run.
Recent History:
During the last 1-1/2 years, had cylinder head rebuilt and reinstalled. Had to run it all winter w/o EGR tube attached because of bad fitting at exhaust manifold. Replaced the fitting last spring and replaced cat back exhaust system. Had manifold hole plugged with pipe plug all winter. Have had a diagnosis of poor compression in the past, have not rechecked compression since head rebuild, but did have a noticable increase in power.
Have checked base ignition timing and it is correct. Valve timing appears to be as it should be. Have not had the opportunity to check for spark during one of the breakdowns, since I had no tools and it was night time.
The codes:
Early in Fall, got 14, 21, 24, 34. The 14 particularly interested me, as it suggests ignition problems.
Just before pulling the distributor, I checked codes again; 14 had disappeared as did 34 (EGR issues I resolved above) but I still got 21 (coolant temp out of range) and 41 (no HEGO switch) So I left the distributor alone and replace the HEGO sensor and cleared codes.
Last code check, just got 21(coolant temp sensor voltage out of range) and 24(air charge or Vane air temp voltage out of range) There is very little heat on cold days, full radiator and I've "burped" the cylinder head on an incline more than once chasing trapped air.
I'm suspicious of the TIF module, since the stalling is after warm up and self corrects. It was replaced once perhaps 12 years ago.

I bought a 1990 ranger with only 38000 miles on it from a online auction from boing aircraft. it never left the flight line and never even had a title. I picked it up from the airport and found out that it didn't have AC like they said, I was a little ticked but that isn't the main problem. When I drive it and it gets warmed up it leaks Tranny fluid from the front of the transmission. The engine does not overheat. It is a 4 cyl AOD automatic with a real thin radiator and a transmission cooler. Without AC the truck isn't the good deal I thought I was getting, and with a bad tranny this is becoming a big OOPS. Why this is happening?

1995 Ford 4.0 ... All the following have been replaced on the truck.
High Pressure Fuel Pump and assembly
Idle Air Control Valve
Spark Plugs
Oxygen sensor (Bank 1 sensor 1 Oxygen)
Fuel Filter
The most recent item that I replaced is:
Coil Pack
Spark Plug Wires
Now, with the Coil Pack replacement, the truck drives good, as long as I do not floor it (After it heats up, about 15 minutes). Basically, if I try to pass someone, the truck acts as if it is chocking out, like it is not getting any fuel.
Before replacing the Coil Pack. It would chock out at any given time, rather just barely pressing the gas peddle, or just sitting idle.
I took it to a friends muffler shop, and he stated that it is not the exhaust that is causing the issue. I am at a loss. Is there anything else that I can check?
The truck seems to drive fine, as long as I do not get down on it, and try to take off fast after it heats up. When it is cold, I can take off like a bat out of hell, and it runs like no-ones business.

I have a 95 Ranger with the 2.3L and it is a five speed. I am having a starting issue. I have replaced the ignition switch, clutch position switch, starter relay and had the starter tested. The truck will not start with the key. I can jump across the relay and it starts fine but will not even click with the key.

I am having an engine issue with my 1995 Ranger with a 2.3L. I have been having a P0340 code that kept appearing after several attempts at resetting the PCM. I gave up and took it to a Ford dealer for diagnostics and they called the CPS bad. They changed it, but the CEL light immediately came on with the code still kept coming up. The service rep. showed me the old sensor, it had a spot on the head of it where it looked like something was rubbing it. I'm assuming it's slightly rubbing on the gear it points to, which is the oil pump gear, correct? The truck runs fine, no performance issues whatsoever. Is it possible my oil pump shaft has developed play in it's shaft, causing this?

Had the top half of the intake off (2.3L) and fixed some vacuum leaks and replaced a power steering pump. Started truck and it ran funny like missing on one cylinder then cleared up then started making a loud knocking noise and running rough. Assumed that it swallowed something when I had the intake off and it got into a valve or into the cylinder. I pulled the plugs and there are no obvious signs of a problem. I also did a compression test and all 4 were around 150psi.
Put the plugs back in and started it and the same noise was there. Removed the serpent belt just in case it was power steering pump related and the noise was still there when I started the truck. Sounds like something is inside the engine still. Going to get a friends bore scope to check further. I guess I will split the manifold again and run the scope in there. Pending that I may also look down the plug holes with the scope. This is a major bummer. Not what I needed.

I have a 95 Ranger 2.3 with a manual tranny. In the past I have had problems with this truck not starting do to a bad inertia switch and numerous fuel pumps. A couple of weeks ago I pulled the truck off of the driveway into the street and let it set there for a few hours. When I went to put it back on the driveway it would not start. I got it pushed on the side of the garage. I did my normal routine of doing a pressure check. I had no fuel pressure so I assumed that it was the fuel pump (as usual) so I dropped the tank and changed the pump.
I got it back together and it still wouldn't start. I checked the fuel pressure and the manifold still had 0. So I started my diagnostic. I have power from the fuse to the fuel pump relay. I then checked the wiring at the inertia switch and found that there is no voltage with the key on at the supply side of the inertia wiring. I verified continuity between power distribution block and the inertia switch. I put in a new fuel pump relay and it still has no fuel rail pressure and there still is no electric signal at the inertia switch. Where to go from here?

I have a 1995 Ford Ranger 4 cylinder and the other day on my way home all of a sudden sounded like a lawnmower, it was very sluggish and would take twice as long to get moving,it also smelled like gas and I used a quarter of a tank in about 24 miles. Someone said it could be the ignition coils...

I have a 95 4.0 EFI inside of my 83 Ranger. Once the motor warms up, it starts to have an idle issue. I have to press the gas, in order for it not to cut off. Here is a video I posted a while back. A person suggested that it could be the MAF needed to be cleaned. I did that, and it did not work.

My Father in Law's 95 Ranger, 4 Cylinder, 5 Speed has started acting strange. It has, in the past 3 weeks just died suddenly, and won't restart. No action at all when you turn the key, as if the battery is disconnected. Wait for 45 minutes to an hour, and it starts back up again.
He has had it to a local shop twice, and the only thing they have done is let it idle for 5 hours at the shop. Of course, it never stopped.
Now they are saying it is the clutch, and depending on the type of clutch, (big or small).
I've been working on cars most of my life, and even had an 87 Ranger, and I've gotta call BS on this. He says it happens mostly when coming to a stop.

. I'm going to FINALLY change the tranny fluid in my 95 Ranger Splash this weekend and need all the feedback I can get! It's a manual trans with miles shy of the 250,000 mark...still on the original stuff!! I'm only the 2nd owner but I bought the truck with just 45,000 miles on her so I'm willing to bet the farm that it's never been changed. It's getting harder to shift from 1st to 2nd and I'm getting a little bit of grinding from 3rd to 4th if I shift too fast. Reading all the threads everywhere online, so many different people have so many different theories from stock Mercon V to MOTOR OIL??? The motor oil thing floored me but I understand the viscosity difference between hydraulic fluid and lubricating oil. figure out what the best thing to replace the original with to prolong the life of this long running wonder vehicle!

What are the steps to fix a broken odometer on a 1995 Ranger? I assume it is probably the gears. The truck has 169 k.

For the last 2 years 1995 ranger 2.3 will run great but every 1-3 months will just stall. Will than try to start it for a couple of minutes and in 1-8 minutes will start back up again as if nothing was wrong and then be fine for another week, month, 2 months etc. It has never happened at first start up in the morning but at times will stall 2 minutes after start (at traffic light of course). At times will turn off to run into store, come outside, no start, try for couple of minutes and then starts up fine. Changed out fuel pump, etc, etc. Biggest problem is no codes and, of course, when mechanic looks at it nothing is wrong.
