Ford Ranger / B-Series :: Surging Idle When Start It Up

My son bout his first truck yesterday. 98 ranger sc 4x4 auto 4.0. Beautiful shape 139000 miles. got it cheap as it has issues. its been parked for a year. It has a surging idle when you start it up. rev it to 2500-3000 rpm and it idles fine turn it off and restart it surges again until you rev it. When we test drove it it ran like it was running out of gas/bad fuel pump, sputter at full throttle but accelerate at part throttle. Gauge said under 1/4 tank of gas. We put 3 gallons of gas in it when we got home and it seems to run fine now other than the idle surge. it had a 174 code(lean bank) but if it was running out of gas it should pull a lean code right? I am thinking IAC or intake leak.

Ford Ranger / B-Series :: 1994 - Running Rough At Idle?

Engine runs rough at idle. Two plugs are black and just replaced head gaskets. I installed new short block and new heads six months ago. I can't seem to figure out the problem and I would like to trouble shoot more before tearing heads off and going any further.

Ford Ranger / B-Series :: 1994 - Rough Idle / Stalling - Catalytic Converter Glowing Red

94 Ford Ranger 2.3L

I started to have a slightly rough idle a while back, but not severe. I figured she was just aging a bit.

Changed plugs. Check engine light came on. Changed plug wires. Then I had a couple of episodes where it started to lose power and idle really rough (stalling). Both times it stopped after a few minutes. Had code read- they said it was coils. Replaced ignition coils. Check engine light still on, but it went a few weeks without power loss.

Tonight the loss of power returned and didn't leave, and I had a glowing red catalytic converter after I limped home 20 miles (hope I didn't do any serious damage, I was stranded.)

Found this post : [URL] .... But there's no resolution.

So, I'm probably dealing with a misfire, and I'm sure I torched my cat after tonight. So any other easy diagnose/fixes for a misfire? I'm a shade tree mechanic- so I know just enough to get myself in trouble. If I can't get a resolution soon it will be off to the mechanic (which, maybe I should have done 1st...)

Ford Ranger / B-Series :: 1994 V6 Rough Idle And Lost Fair Amount Of Power

I have a 94 Ford Ranger 4x4 4.0 V6. It has developed a rough idle and has lost i fair amount of power. I cleaned the maf sensor and iac valve. Along with replacing an o2 sensor that was reading bad, with no improvement. The guys at O'reilly took a look and think I may be dealing with a timing issue or a warped valve. My question here is to found the culprit? I'm very inexperienced at working on vehicles and am damn intimidated by the scale of a project like timing. I should add that while traveling on the highway in high gear at low rpms, it develops a rough stutter. I can either power through it or ease off to get it to stop, but it resumes shortly after. It almost acts like an egr valve stuck open when on the highway. But that doesn't account for the rough (a consistent put, put, put...) idle.

Ford Ranger / B-Series :: 1994 - Won't Start After Warm Up?

I have a 1994 Ford Ranger 4.0L 4x4, 130,000. I love this truck but about a year ago it started not starting after it warmed up short distances in the summertime? It start right up on cold crank...Runs smooth idles like a champ...but if i shut it off..wont start for 20 to 40 min??? It doesn't happen in the winter months??? So I changed the fuel pump, filter, relays. I feel like it has something to do with the Ignition Control Module. Would that come up in a code?

Ford Ranger / B-Series :: 1994 4.0 Sometimes Will Crank And Not Start

94 Ranger, 4.0, Automatic, 280k miles. Normally starts and always runs fine. Sometimes will crank and not start. Fuel pump replaced Feb. 2015 and again Dec. 2016. Have had it towed 3 times. Always starts when it gets to the mechanic. Sort of reminds me of vapor lock on the old cars with carbs, because if it sits long enough after not starting, it will start, no problem. Never died out or even coughed when running and plenty of power. When I take off the gas cap, it sucks in air like a whale. Twice I did that and it will not start right away, but if it sits for an hour or so, it starts no problem. Just bought a new gas cap 10 minutes ago and looked in a Haynes manual and a " gas tank vapor valve assembly" is mentioned. I don't want to change parts just to see what happens. Mechanics say there are no codes shown.

Ford Ranger / B-Series :: 1994 - Engine Cranks But Won't Start

My kid is using my 94 Ranger with 215,000 miles. It quit while he was on his way to work. Engine cranks but won't start.

Fuel pressure at rail was 12 psi (Key on eng. off). I replaced fuel pump. Pressure at rail up to 20 psi. Still cranks, no start.

I replaced fuel filter. Pressure at rail up to 30 psi. Still cranks, no start.

Replaced distributor cap/rotor and plugs. I have spark at plugs.

Chiltons from 1994 doesn't list a rail fuel pressure. I see new fuel pressure regulators are set at 41 psi. I pulled mine and hooked air to it. It (FPR) cracks at 37 psi. I have lots of flow returning to tank, so I assume the fuel system is working correctly. I've never replaced the timing chain/sprockets. Distributor rotor spins during engine cranking. When I rotate the crank pulley to 0 Top Dead Center the rotor is pointing to #1 on the distributor, so I don't think the timing chain has skipped a tooth on the sprocket??????

Ford Ranger / B-Series :: 1994 4X4 Would Not Start / No Spark And No Fuel Pressure

Sons 94 ranger 4.0 4x4 Auto 185k got him to work yesterday but would not start to bring him home. No spark, checked with timing light, and no fuel pressure. Searched and read alot of tips from Pawpaw so I tried a few things with no luck. Swapped the relays around, inspected coil pack and plugs. CEL was not on and goes out while cranking. I have a OBD scan tool but this truck must be too old or I need finding plug. Crank sensor maybe?

Ford Ranger / B-Series :: 1994 - Hard To Start - CEL On - Power Loss

1994 Ranger .. Last wednesday I had to get a jump because the lights where left on. Everything was normal on thursday. Friday morning. I went to go start the truck and notice that it would try once to start and then try a second time and it would start. Today I was driving it. The check engine light came on and when I get the RPMs up to shift up, I would loose all power and have to wait till it gets down below 10mph before I would get the power back.

Ford Ranger / B-Series :: 1994 - Lifter Knock At Start Up / Throttle Hold Over 3k?

I've got a '94 Ranger with the 4.0L OHV and an Automatic trans. When I start, hot or cold, it has quick lifter knock for only a fraction of a second. This same knock comes back if I hold the throttle over 3K with NO LOAD on the engine. With any load, I cannot make it knock. With no load, though, it becomes very loud, especially with more RPMs. at idle and slightly above, there is a slight tick that can only be heard with the bonnet up, and then it is only slightly noticeable. I think that this tick is unrelated, but I figured I should share that information. For oil, I run Pennzoil high mileage 10W-30, changed 3000 miles religiously. Purolator filter, PL30001. I can understand the startup knock, but I can't see why it seems to produce the same knock at high RPMs under NO load.

Ford Ranger / B-Series :: 1994 - Truck Won't Turn Over Just Making Noise Like It Wants To Start

The truck just won't turn over makes a rrrgh rrrgh noice like it wants to start, I push the gas peddle to the floor and I should smell a lot of gas but don't!!! I added oil when it died at the store last night and it started up but the oil stick indicates oil is fine??? Pulled the diode out this morning put it back in the truck would not start just made that noise but turned it off and reseated the diode and it started??? These things may or may not have anything to do with the problem. Could it be electrical or oil pressure gauge sticking or something else that I could tell my mechanic and he could fix so I don't get stuck????

Ford Ranger / B-Series :: 1999 - Running Rough / Missing And Surging At 50 To 70?

I live in Kansas and was home in Georgia for the last 2 weeks. The truck drove great there after a fuel up started missing and surging at 50 to 70 thought it might have been bad fuel. waited till it was low added Lucas fuel treatment and premium gas still was doing it. no check engine light. went to Advance and fuse for light was blown they checked and was getting mass air flow code. unplugged it and seemed to be better, not perfect but better. plugged it back in and went to do it again. Changed mass air flow night before the drive back to Kansas. Ran well from Savannah to north Georgia then started doing it again the rest of the way home. Going to have advance check code again.

Ford Ranger / B-Series :: 1999 - Crank But No Start / 3200 Rpm At Idle

1999 mazda B4000 4WD 178000 miles 5 speed manual, I've been having a crank no start problem but after a few tries it would start, a week or so ago it was really cold (23) it wouldn't start so I opened the air box and shot it with starting fluid it took about 5 long sprays but it started.

It ran up op 3200 rpms and won't go back down, took it to my shade tree mech. he hooked it up to the diagnose thing it showed no codes, he poured water over the motor it different places and toward the back it idled down for a second so he says "blown intake gasket' so we replace upper and lower and sure enough we could see where there was a bad spot on the upper and a cleaner spot on the port.

That was not the problem it still idles at 3200, I mean wide open screaming, could the starting fluid have done something? Now he says "blown head gasket" I never had any idle problems before matter a fact besides the hard starting problem that started it was running just fine, what happened?

Ford Ranger / B-Series :: 1999 - At Start Up No Idle - Brakes Too Sensitive?

My manual 5 speed 99' 2WD 2.5L Ranger is starting to have some small problems here and there. My main concern is when I start the vehicle sometimes, there is no idle. The vehicle will turn over and if I do not hold the gas pedal down it will die immediately after about 2 seconds.
If I hold the gas down so the RPM's stay up (Around 700 RPM's or so, something just a little above 0 to keep it from dying) after about a minute, sometimes few minutes the idle will kick in and I do not need to hold my foot on the gas pedal to keep the truck from dying.
This is about all I know from the problem besides that it does not matter how long my truck is sitting. For example, my truck was sitting for 5 days and I came home and started it up just fine, but after I drove it a few minutes later and stopped driving, when I went to drive it about an hour later the symptoms came back again.

Also, My brakes are acting a little funny. I went through when I first got the vehicle and bled the brakes, took the front rotors in to auto zone or another shop and had them fixed up, and new brake pads. Sometimes when I first start driving the brakes are extremely sensitive, to the point where I apply a little bit of pressure and my truck will start skidding. This goes away after driving for a little bit though.

Ford Ranger / B-Series :: Rough Idle At Start Up - Spark Plug 4 Keeps Going Bad

I'm getting tired of the same problem about every 6 months. Plug #4 keeps going bad. Its been doing this for years. It starts with rough idle when first starting up that clears up quickly then eventually it leads to a misfire when accelerating. Every time this happens I replace plug #4 and its good to go. Just recently (roughly 6 months ago) did a full tune up and all new injectors. About a week or 2 ago it started its rough idle at start up and just the other day it started misfiring again. What would keep causing this??
