Ford Ranger / B-Series :: Truck Was Idling Rough Until Warmed Up
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.
Ford Ranger / B-Series :: 1990 Truck Won't / Hard Start When Cold
My 1990 4.0 refuses to start when the air temperature outside is at approx 40 degrees or below. It will crank until the battery runs dead if I let it. At approx 50 degrees farenheit the truck takes forever to start and always backfires out of the tailpipe and intake manifold (blowing off a hose on the vacuum tree) before it starts. If I can get it to backfire, it will start eventually. If it does not backfire, then I can run the battery dead and the truck still refuses to start. This condition has grown from a little problem to a huge problem over the past 6 months. Here is what I have done so far, including regular maintenance items.......
KOEO test checked OK
KOER test returned code 77 multiple times (TPS).
Replaced Throttle pos. sensor
Replace Idle air bypass valve
Subsequent KOER test came back with no more codes except 11 - OK
Load tested battery
Made new heavy gauge battery cables for + and -
New plugs, wires
newer starter
Changed coil pack for known good one off my explorer
Visually inspected hoses for vacuum leaks, replaced 1 cracked hose

Ford Ranger / B-Series :: 1990 - Rough Start - Running Lean?
]I recently bought a 1990 ford ranger with a 2.9 @187,000 miles. That being said I went through and changed a few vacuum lines, the oil, air filter, pcv/grommet, and fuel filter.
The problem is it hates to start. I could crank on it for 10 seconds and not a single thing. Sometimes if i turn the key to the off position, wait a second, and try again, Ill get the truck to fire. When it does fire up it just reeks of the lean exhaust. It also gives me some hesitation when I rev it. I did a fuel pressure test (KOEO) last night and it gave me 32 psi and within a minute the needle fell to about 25 psi. I hear the fuel pump run for only 2-3 seconds too.
I've already pulled the MAF off and cleaned it, replaced the TPS, and did a fuel pressure test. The fuel filter is brand new
Ford Ranger / B-Series :: 2004 Truck Dies / Stalls While Driving
The problem : I bought a 2004 Ranger truck and after two days it started to hiccup, or stall or die while driving, then because the truck is manual, just start up and keep running. It was the strangest thing.
I gave it to a shop, and after checking the electrical, the ignition, the fuel system, the drive train, and ten hours of troubleshooting, they came up without an answer. So they gave me the truck back.
Answer, a few days after taking it back:
I had told the shop that it had been sitting for 6 months, May till January, but when I told a mechanic friend a bit later, he still suggested 2 bottles of gas line antifreeze in the tank, before the next tank fill. I did that, and there was some improvement.
Next, When I replaced the balding tires with new Nokian Winter tires, the tire shop, (Kal Tire), told me that the air cleaner was incredibly dirty, and asked me if I would like them to replace it. I said yes, thinking that it might just do the trick, as no one in the forums I read, had mentioned it.
Success! No hiccup or stalling and it has not died since.
Ford Ranger / B-Series :: 2000 3.0L - Idling Rough / Hesitation While Driving
Finally back able to start working on the Ranger and have a few questions.
When I got this thing back from my son it was running rough. I've fixed all the codes it was getting so no luck there now. Not sure how to explain it but, it feels like it is cutting back when driving at a steady speed and it idles rough. Not really like a miss but more like a hesitation when driving.
I've cleaned the MAP and IAC and changed the fuel filter. I also pulled the plugs and they looked good. My son installed new plugs and wires but he used the E3's and not sure how, or if, you're suppose to set the gap. I haven't checked the PCV yet because haven't figured out how exactly you get it out without pulling the intake.
So, where to look next? I'm kind of thinking the cam sensor but think I'll leave that to a shop sense I want the shaft replaced at the same time.
Ford Ranger / B-Series :: Truck Almost Dies And Starts Sputtering - Spark Plug Caps Pop Off
My 2003 2.3L used to run bad... it had a lot of lag to it when i would try to accelerate. The check engine light was on so i got it checked, and the reading said o2 sensor high voltage or something like that... anyways, i purchased a new sensor (i researched, and found there is only an upstream o2 sensor), replaced it, and the truck ran WAY better, no more lag during acceleration, it was crisp. As i was driving home one day, i was accelerating up a hill, and at about 4000 RPM, the truck almost dies and starts sputtering.
The check engine light started flashing, so i new it was serious, but luckily i was able to make it back to my house. When i got home, i looked under the hood and noticed that #2 & #3 spark plug caps had popped off the spark plugs. What I don't understand is what would have caused that to happen in the first place.... Is it a clogged Catalytic convertor, or is the o2 sensor bad.... Ive read different opinions and technical diagnostic possibilities, but man, i don't want to throw a bunch of money at a truck that I'm really going to have for a few more months. but I need to get it fixed in the mean time.
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 :: 2004 - Hard Starting / Rough Idling / No RPMs
backed out of the garage fine later in the day went to put it away started hard would not idle and only rev to 2500 .cleaned map sensor,egg valve tested and it works.cleaned the IAC and that works ,fuel pressure is 58psi. starts hard it would idle now it doesn't dies, no code . with 58psi could the pump still be bad? it has 18 pounds of vacuum. where is the vacuum line for the fuel pressure regulator on the motor?

I have a 2006 Ranger XLT 3.0 that is vibrating hard/rough idling, cel is on (solid, not flashing), has trouble accelerating with pedal punched. Will sometimes get a sudden burst when pedal is punched with rpms going up but most of the time no to slow raise of rpms with pedal engaged. Hooked code reader up to it and read ignition coil. Replaced the coil and changed plugs and wires. Truck still not running right. what gives? Is this a fuel pump, cats clogged, cylinder issue?
View 4 RepliesFord Ranger / B-Series :: 1997 - Rough Idle At Startup / When Rev Up Chugs Real Hard Then Dies
I am currently working on a 97 ranger with a 4cyl and 5 speed. its having some idle issues that i cant seem to pin point, you can start it and it will idle rough then when you rev it up it chugs real hard then dies. used my scan tool and all the sensors are good, fuel pressure is good, good compression, all 8 plugs are firing good and no codes. The other deal that has me a little confused is when I unhook the hose that runs from the air intake tube to the valve cover, I get a lot of vacuum at that port on the valve cover that the hose hooks to. Also when I plug it and pull the dipstick, I get vacuum at the dipstick tube. never seen this before but at the same time I've only messed with very few of these trucks so I don't know whats normal.
View 6 RepliesFord Ranger / B-Series :: New Plugs Now Truck Running Rough
Although my lil' truck (2006 Ranger XLT, 2WD,with 4-cyl / 5spd, and 115K miles) has been running just fine since I bought it about a year & 5K miles ago, I suspected it still had its original spark plugs and I figured I should change them before problems arrived.
As I suspected, the plugs that I took out looked to be original. I measured their gap and they all had excessive plug gaps - around 0.052" gap. I installed the four new AUTOLITE APP104 (double platinum) and checked their gap, and they were a bit tight at 0.042". My book says they should be at 0.044" gap. But I installed them at 0.042 anyway, figuring they'll burn wider in time.
One by one, I smeared a small bit of never-seize on the plug threads & at the plug-to-cyl head tapered edge. I smeared a dab of Dielectric Grease around at the top of the plug to ease the plug wire re-install and hopefully calm any possible arching. The plug wires came off the plugs easy enough and went back on just as easy.
I hit the key and the engine fired right up. It idled rough as expected. However, it continued to idle rough and if I raised the RPM level, it would respond, but still ran rough. It is throwing a 'Check Engine Light' on the dash cluster now - whereas it wasn't prior to the new plugs.
Ford Ranger / B-Series :: 2003 Truck Idles A Little Rough - Code P1450
Where to start looking to resolve this code. It is not an intermittent code. It returns after about 3 to 4 key turns. Truck idles a little rough but runs fine. I have looked up the code and causes but wondering how to deal with this directly and fixed it. I'm wanting to sell my truck for something bigger and would like to solve the issue before hand. 2003 Ford Ranger Edge...
View 4 RepliesChevrolet :: 1990 Truck Dies At Random While Driving
My truck is having a problem lately where it will suddenly die while driving. It feels like it loses either spark or fuel and happens about 20-30 minutes after I drive it. Once it dies you can turn the key off and restart it and it will fire up and run again, for how long I'm not sure because I'm almost home about that time. It has a fairly new fuel pump, 2 years old, a fuel filter the same age, new cap and rotor, new air filter, probably could use some new plugs. I replaced the TPS with an older one that I had laying around and had no change in performance. I get a 34 and 43 code (MAP and knock sensor) when I do a diagnostic on it.My question is do you think a MAP sensor or knock sensor would cause this kind of failure before I go out and buy them? I'm leaning towards the MAP sensor but not sure that it would have this kind of an effect on the engine.
View 4 RepliesFord Ranger / B-Series :: 1990 - CEL Only On At Idle
I recently acquired a 4.0 Ranger 4X4 Auto for my use in Costa Rica. It runs fine but it'll illuminate the CEL within a few seconds of starting and whenever revs fall below approx 1000. When pulling off the line or accelerating, the light will go out but comes back on when the throttle closes. The previous owner has replaced the MAF and idle air valve. I've corrected a lot of issues with the vacuum system and think it's back where it ought to be. I know I am going to need to pull the codes but I'm back in Dallas now and can't do it yet. Need general list of affected parts that I could buy here and take back down.
View 14 RepliesFord Ranger / B-Series :: 1990 - Overheating While AC Is On?
I got a 1990 Ranger 4x4 2.9l that loves to get hot only when the ac is on. The engine was rebuilt by me about 2000 miles ago and I made sure to have the block boiled in order to clean out any crap that could've been built up in the water jackets. So far the radiator, cap, thermostat, and fan clutch have been replaced. The fan shroud is intact and the condenser has a few bent fins but not many.
Here in Vegas we're looking at 100+ from 10 am - 4 pm so the ac is a must. I could be sitting at a light all day with the ac turned off and the truck doesn't have an issue. When I turn the ac on though the truck almost immediately begins to get hot. The engine drops maybe 100 rpms and the voltage gauge also drops a little. At night if I'm running the ac the voltage drops to what looks like 10 volts.
While the ac is on there is an immediate loss of power as well. In my head I'm thinking a failing compressor, water pump, and alternator are at fault. It doesn't matter if the truck is moving either, the temp still climbs.I know the rangers are funky with their cooling so when I burped the system i turned the heater on and lifted the front end about 1 ft off the ground with the cap off.
