Ford Ranger / B-Series :: 1994 - Running Rich / Strong Exhaust Smell
May 30, 2015
1994 reg cab 4.ol 13ok.. my wife just got it, been doing some small things like replaced dome light, replaced cargo/third brake light, truck starts and seems to run ok. but i get a headache in it which i believe is carbon monoxide, has a leak or something? i text previous owner, he said he replaced 02 sensors, but didnt say if they were bosch or a good brand.. also trucks has a oil pressure and coolant temp gauge fitted on by the gear shift as the dash gauges for those functions are out. Does this mean the CTS may not be working and affecting fuel/air I do not know these trucks i only just found out what this strange silver looking thing was it is the IAC, I Believe, then there is this black plastic vacuum type cylinder by the passenger side firewall, what is that? and right against the drivers side fire wall is a small reservoir type thingy, is this something to do with ABS? i do have an ABS light on, was hoping it was the bulb out on the third brake light or something quirky like that no such luck its still on after starting engine. but i am concerned about this running rich/strong smell as we really cant take it far as is it, its dangerous, may have to get a smoke test? Just got the truck, trying to get caught up..

I have a 87 ford ranger pickup, it is running extremely ruff. You can smell the exhaust and it smells super rich and is even spitting fuel out of he exhaust. when I bought the truck the wires were cut on he oxygen sensor, so I put a new oxygen sensor in it hoping that it would lean out the fuel. The truck has duel tanks on it, but the back one is off and it is draining fuel out of the line when it is running. I don't know if the catalytic converters are plugged too, the truck only has 65,000 miles in it. or maybe its a vacuum line leak?

My car was running rough, with white smoke and strong gas smell coming from exhaust. It died out on me a few times as if it was not getting enough acceleration. Well, I coded it and said misfire cylinder 3 and 4. I also tried to shut down 3 and 4, but did not shut down. I switched 3 and 4 with 1 and 2, still did not shut down cylinders 3 and 4. Engine coils are good, engine module was tested and passed twice. Ok, fuel injectors 3 and 4 were leaky and I changed them out. New spark plugs and boots. New oil and filter..(There was gas in my oil and oil in my air filter.) With the new parts....my car sounds soooo much better!!! still a little rough, does not bog down, but it still has the strong gas smell and white smoke from exhaust..(gas smell soo bad I had to open all doors to the garage!!) What else could be wrong?!?! I'm getting frustrated!! It also has NOT ever over heated, does not run high.

Got a problem with the '94 Ranger. Something keeps draining the battery. For reference, the truck is an XL, manual 4x4, 4.0L, 5-speed. I've been trying to keep driving it so I could try and diagnose the issue. At first, as long as I cranked it every day, it stayed charged up, but now it has gotten worse. It will run down in an hour or two. I know figuring this kind of problem out is tough, but I thought maybe some others of you may have experience in this area that might benefit me.
Based on a gut feeling, my first idea was that there was something going on inside the AC compressor. So, I disconnected the compressor, but that wasn't it. My plan at the moment is to replace the wiring harness between the battery and the starter. The current harness is pieced together (not my doing), and whether it fixes this problem or not, it needs to be done. Another thing I've thought about is the ignition switch. It acts "funny" to me, but it has never really given any trouble.
My son needs to take this vehicle back to college with him in a couple weeks, and I need to get it figured out.

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.

So I got everything fixed on my 94 ranger so I thought. Now it runs right on the "L" on the idiot gauge on 90 degree plus days running the AC. Also it seems to lose power at times and not even want to do 70. I think new coils, new plugs and wires may work. I also have an intermittent check engine light that pops up on occasion, but clears when you kill the motor and start it back up. I was really starting to like this truck despite it not being my style(I like square body rangers) and it being a 4 cylinder. I like the MPG but am starting to think the 200k engine may be fading

I have a 2003 ford ranger 2.3 vin d 5 speed, this truck originally... Took it in for wires plugs front brakes fuel filter battery and added a small cold air intake. We discovered a valve cover leak and while repairing guy drops a screw into a valve and when finished he started it lodged the screw between the valve, shearing off a cam sprocket bolt. Throwing the timing. 2 valves on the exhaust side were bent and replaced. no damage to the head.
Timing was reset and the truck was running. 2 days later truck is running/had a hint of exhaust smell then started bogging dying and shaking, at which time we got an 02 bank2 lean code and fixed that. it cleared code and didn't fix it. From there we replaced coil, imrc intake bc of a crack, tried and check all vacuum, reset the timing. Timing would slip before but no longer than 10 minutes every time truck started.
Found the hole in the timing cover that holds the bolt to torque? to harmonic balancer was broke. replaced along with the diamond washers and cam sprocket bolts. timing finally held crank sensor was adjusted. truck came home for one day running good, we had removed the cold air intake and replaced the factory air intake. next day it was so slow outta first gear, you must baby the throttle, if you floor It, it sputters and kinda pops, truck stays slow all the way to about 10 mph and 2000rpm then it begins grabbing speed, 3000rpm is where this truck shifts the best, 2nd is better, third better than that.
As rpm increase the truck runs better, it idles steady at 1100-1200rpm at stops with an audible miss and then struggles again on takeoff. Here what im wondering, the truck has an abs sensor that just came on, but no codes showing now.tomorrow I wil run matko determinator 3.0 on it. and test the catalytic converter. first how do I check the timing belt to see if it stretched? do these trucks store the p.i.d.s. koer or kams that could cause one, all, or any of this and if so do I have to have it flashed from ford or can you manually do this without a drive cycle test.

After I've been driving a bit and stop at a red light, drive thru, etc. I've noticed a strong gas smell. I drive with my windows down so I really notice it. I've searched all over the car and can't see any leaking. In addition to this, after I shut the car off for 20-30 minutes, when I re-start it, it runs really rough like its flooded until it clears itself out, along with the gas smell. The consensus seemed to be that its the pressure regulator/vacuum line. Where exactly is that located?

Here is a video of my sonata exhaust running rich and "popping" when i ease off the gas when in P/N (haven't driven it enough to recreate it on the street in gear). I also included a teaser pic of my plasti dip project which is almost done and ready for me to enter the Ride Of The Year.

2002 Ford Ranger edge 3.0 flex ... Truck was running fine and giving me no issues. I woke for work the other day and went to get coffee and truck wouldnt start. I could hear fuel pump running and knew it wasnt that, it was acting flooded. So today I pulled fuse from fuel pump relay, and got it to start. Put the fuse back in and ran to gas station. On the way to the gas station it started running really rough, very low and rough idle, trying to stall out. I noticed it had black smoke coming from exhaust. I got it home, and got it to start barely, and it has the same very low and rough idle, but my oil gauge was going crazy, flickering back and forth all crazy, and the idol is terribly rough and eventually stalls out. Earlier today I did put new spark plugs in it, but not sure that has anything to do with the issue. I also hooked it up to a computer and it isnt throwing any codes.

When firing up the engine cold it runs really rough, smells very rich all the time, even warmed up. No codes set, fuel trims are within 5-10%. I've replaced the front O2 sensor, swapped crank & cam sensors, Map sensor (have lots of spare parts) & I'm sure there was more things I've changed but can't remember. I have a snap on scanner and everything is within parameters.
I have not checked the EGR valve or solenoids yet. It's a 2006 Santa Fe 2.4l 5 speed, new timing belt & balance belt replaced when I dropped this engine in. Is there a common problem with these that I could begin looking for?

We've had a run of -20 to -40 weather here for the past few weeks.
A few weeks back I noticed that when I climbed into my truck after command-start warm up for 10 minutes, and I could smell strong exhaust.
I figured it was hopefully the wind, or an isolated event.
Over the past few weeks I've used my truck for 3-4 more around town runs and every time I warm it up I get the strong exhaust smell. It's that rich, eye watering, sickening exhaust smell. I also notice a small yellow frozen puddle under the exhaust tips that wasn't there before.
It's bad in the cab, but even walking around outside the truck and the smell is sickening. I actually just started the truck and I could actually smell the exhaust smell faintly, from inside my house! This has never before occurred. Prior to this, a person could hardly tell it was a diesel by the smell of the exhaust.
Once the truck is up to temperature the smell seems to disappear, or at least lessen.

Not at the exhaust, but from the engine compartment. Have to open the windows at a stoplight. Can also smell it when I walk past the parked truck. What's up?

I have a 94 ranger 4L. I am looking for a more loud exhaust sound in/outside the truck and at idle. I have had a cherry bomb turbo on it and it was ok but not loud enough for my liking. I just picked up a flowmaster 40 2 days ago and it sounds good but again just not loud enough for my taste and kinda a lot more. I was looking for a louder muffler that is not a glasspack and would like to stay under like 80 or so.
I also thought about getting a high flow cat which i think might make some more sound but was not sure. Im running the stock pipe which is 2" and end in back of the wheel on the right. I look at the Hooker Headers Maximum Flow Muffler which i thought would be louder b/c it's more straight through the muffler so it would put off more sound better. What would u recommend for something more loud ?

There is no noise that would indicate a hole in the muffler, just the exhaust smell. I'm wondering if the catalytic converter is going out? If it is the catalytic converter, will it strand me on the highway eventually?

I'm going to take my Elantra in to get it checked. My Elantra is a 2013, got it in March. Over the last few weeks, I would say, on 4 days or so there has been a STRONG exhaust smell. No smoke, nothing else but a smell. If I'm pulling into the garage with no idling, just pull in and park, I get out and the smell in the garage is very strong. I have to leave the garage open for at least an hour if not more to air it out. The cab ends up having a light smell inside the next day still.
If I'm parking outside when I get out I can still smell it, but not quite as strong, because I'm not in an enclosed area. I don't think it's an exhaust manifold leak, because I don't hear the popping. My best guess is it would be in the tail pipe area pre-catalytic converter, or in the catalytic converter if it is in fact an exhaust leak.

For the last few months, I've had an annoying problem with my 2003 Liberty. If I'm driving the car with the blower on (i.e. when it's cold out), whenever I stop the car and am idling, I get a very strong exhaust smell coming in through the vents. If I turn the fan off, the smell goes away. At first I figured it was due to being behind other vehicles, but now I've noticed that it does it all the time, even when there's nobody else around.
I brought the jeep into a shop a couple of weeks ago to deal with a separate CEL issue (evap leak - fixed by replacing gas cap) and I asked the mechanic to look for an exhaust leak. He said he didn't see any readily apparent problems with the exhaust line.
I'd like to deal with this because it's not very pleasant to inhale exhaust fumes through the vents. I intend to take it back in - but is there anything I can tell him (i.e. like, a particular part of the exhaust system to inspect more carefully) that will solve the problem?

The exhaust from my caprice if thick and white. And there's a strong carbon smell. Could this mean my cat converter is bad?

Not long ago my wife said the air recirc doesn't work any more on our '04 V8 and I had to admit that I agreed. After a little investigative driving, I noted that heavy acceleration (or uphill climb) causes V8 to tick (can hear it reflecting on passing walls, for instance) and strong smell of exhaust in cabin.
I thought it might be a manifold/exhaust system leak causing the noise and the exhaust smell. Seems to be only when driving aggressively or climbing. Soonest the local dealer can see it is 7/21 (16 days from now). You think it safe to drive?

I purchased a 2011 Chevrolet Impala last year with 14,000. When the car reach 26,000 I begin to smell a very strong sulfur smell coming from the exhaust. I took the car to the local Chevrolet dealer and was told that the particles in the catalytic converter begin to break up at about 26,000 mile and the result is a sulfur smell.
I didn't believe that all Impalas had this problem. So I took it to the Chevrolet dealer in the next town where I personally know and trust the maintenance chief. He put his two best men on the car and could not find anything wrong. I was told to try another gas station which I did but it did not work. I now have 31,000 miles on the car and the smell is very strong coming into the passenger compartment when stopped.
