Ford Ranger / B-Series :: Runs Rough For About A Minute After Engine Started When Cold
Feb 19, 2014
This has been an ongoing issue for about a month. When I start the engine after it has been sitting and is cold it runs ruff for about a minute then smooths out and runs fine. I pulled a P0304 code (cyl.4 missfire) but I do not get a CEL.
I checked the plugs and they were ok but I changed them and the wires anyway as it just turned 50k and the plugs were original. I could live with a little cold ruff idle but the code throwing bothers me. The truck is a 2000 xlt 4x with auto trans. and 4.0 engine. This is my second 4.0 ranger but I have only had it for about 6 months.

I have a huge problem. My 94 ranger 2.3L 5 speed manual transmission, has problems with idoling while it's cold, has no power going uphill and stalls when I slow down to stop. This is all after putting a new motor in. The old one was running ok with 310,000 but lagging bad. I figured with the driving I do, a new motor wouldn't be a bad thing. Boy, was I wrong. It has been a nightmare. But once the truck is up to operating temperature, it runs so smooth you wouldn't think there was a problem. But let it cool off, restart, and boom! There it is. We have changed so many parts and sensors with absolutely no change to the original problem. It's very frustrating. I just can't let this problem win. I will figure it out.

1990 Bronco II, 2.9l, auto, 4x4. Was running just fine. Sitting in Park just idling away. All of a sudden, just starts running real rough, ticking, etc.
Towed it home. This morning, started up OK but still running really rough.
While running, pulled spark plug wires one at a time from the drivers side. Had no effect but could tell the wires were sparking as I held them up to metal.
Turned truck off. Drivers side exhaust manifold COLD, passenger side HOT.
This sounds real bad to me. Am I missing something simple that could cause the drivers side of the engine to not work?

I just changed the plugs and wires on my 2008 Ranger 3L. Now it runs rough with no power. It was fine before I did the work but I thought I should change the plugs at 215000KM. I used Ford wires but unfortunately I used Bosh platinum plugs and now think I will change to Ford plugs. Do you think the Bosch plugs would be that bad for the Ranger? What is the belt tensioner torx size? I had to move the A/C compressor over to get the #4 plug but had a very hard time trying to loosen the belt.

My pops has a 86 ranger with a 2.9. And what its been doing is, it will start up just fine then u give it a minute and itll start to run very rough like a bad miss fire, then if he revs it up for a bit. It will clear out and then run just fine until he starts it up again and it seems to do it more the colder it gets and it smells very rich. Iv checked the injectors and there fine, what other things could it be ? O2 sensors oorrr

I am working with a friend on his 99 Ranger with a 4.0 . When first started it will idle rough and hesitate for the first 300 feet or so, and then clear up and run smooth the rest of the day. If he lets it set for 6 or more hours it will repeat the problem. He has taken it to a local Ford dealer and they have replaced spark plugs, plug wires, coil pack, cleaned the throttle body, checked the air idle motor and passage.
He has had it to the dealer 3 times and their latest plan is to pull the heads @ a cost of 1500.00 to start. Since it runs well, no coolant in oil or oil in coolant nor loss of either fluid, I couldn't figure why they want to pull the heads.
To date it has not thrown a code, I ran it on a New Generation Star tester and cannot find a code. The truck runs great after the first intial start up and does not give any signs of cutting out or lack of power. My guess is it is losing fuel pressure overnight and is taking a while to reprime. Original fuel pump and 160K miles. Will do a fuel pressure test this weekend.

I have a 99 F150 Lariat 4x4 with a 5.4, 150,000 mile on it. About 2 weeks ago I blew spark plug out on #2, and a friend who said he has heli-coiled a bunch of these tried to do mine and ruined the head. Anyway, I called a local engine shop and got another PI head, only I used my cam in it. Torqued it as per the book, etc... Mind you that the engine ran perfect before all this.
Got it back together with all new plugs, new exhaust manifold, and 2 new COP's. When I start it-it runs rough for about a min, then straightens back out to run perfect again, and after a few seconds you can hear a solenoid click, then it goes back to missing again. This goes on and on... I went through all the vacuum lines and checked them, checked the egr valve, put on a new IAC, new PVC, cleaned the MAF, and checked everything else with a DVM.
I took it out and drove it.... Runs good for a minute, then it goes back to missing, then back to smooth again. This just keeps going on and on. I noticed when I hear that click, it sounds like a mad rush of air being sucked in, but I cannot locate it. I ordered a new set of COP's to try next. I can understand if it just plain missed all the time, but this it intermittent. Also, the only code I can get is a too lean on bank 1, so I replaced the 90's and the pvc valve. Now no codes but still in and out of missing. It ran perfect before the new head.

I understand there is not much adjustable on my 98 Ranger (2.5L) as far as idle speed and mixture. It runs rough when started cold. Is this a sign to replace spark plugs?

I have a 98 ranger with 2.5 and 225k mostly trouble free miles. This engine has never used a drop of oil and ran good. In Dec 3 miles from work started running poorly and sounded to knock the more I asked for power. The CEL started flashing I made it to work and it idled rough but more rpms smoothed out. Took it to mechanic says he did a compression check with little or no compression on #1 & #2. #3 & #4 fine must have broke rings. Doesn't seem right to lose 2 cylinders at the same time out of the blue. Could anything else be causing these symptoms or time for a heart transplant? He hasn't opened anything up yet.

Quick back story I bought a 1999 Ford Ranger It is a 4 cyl with an auto trans the guy said it had some trouble with the tranny (major understatement) he also forgot to mention he cut out the CAT. so running a 4 banger off the header.
When you start the truck it rough idles but you have to hold the gas down til it warms up. You can shift into reverse but it labors the motor and the motor will not up the rpms kinda stays at idle and wants to die no matter how hard you accelerate and you can't move up a slight incline.
When you shift into drive you have to rev the motor to 3 grand an it will catch then move slowly forward. no matter how high the revs go. The fluid levels are a tad above the full level and a bit dark for my liking.
Ok, I used an OBDII scan tool from the parts store and it came up with 3 codes P0351, P0352, P0500. From my internet search the first two seem to be coil related which explains why the motor is running like garbage. The last may or may not have to do with what the tranny is doing.

I have a '92 Ranger with a 2.3 liter engine. She starts and runs a couple of seconds and shuts down. I'm thinking maybe a fuel pump is not putting out thepressure needed. Gotta go to work tomorrow and gotta get the truck running today.

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.

Just recently my 2003 3.0 Ranger has started to rev high between shifts. With the clutch in the it will continue to rev high for 8 to 10 seconds. Where should I begin to look to correct this problem?

I've got a 1992 Ford Ranger 2.3L with about 240,000 miles on it. The check engine light started blinking on and off pretty regularly so I pulled the OBD1 continuous memory codes and came up with this.
327 - EVP/EPT circuit below minimum voltage
328 - EGR closed valve voltage lower than expected
334 - EGR closed valve voltage high
I can't say these codes mean a whole lot to me besides I've got issues with my EGR valve and possibly the EGR valve position sensor. I was thinking I'd start by replacing the EGR valve.

Throwing codes ... p0136, p1131, p1151 acts like it going to just stop then will take off, at a stop light it will sound like it has a large cam in it... It is a 1998 4.0 V6 automatic tranny.

2002 Prius that idles really rough for a min or two when first started. Recently got check engine codes 300, 301, 302, & 303 for misfires. Also have had the red triangle with a 3191 fail to start code. When I get the 3191 it will start after a couple attempts. Mileage has dropped to mid 30's. 227k miles & other than the idle problem the car runs well.

I have an 89 Ranger 2.3l with 255,000 miles on original engine. The engine runs like brand new. I'm just curious as to why it's extremely sluggish when cold. Example, it was 3 degrees this morning and I literally couldn't get over 45 mph for 5-10 mins. Everyone was passing me. No knocks or other strange noises just doesn't have any power. Once warmed up its completely normal. Obviously my '01 4.0 Ranger doesn't do this so I was mainly interested in why? Do they use different metal materials, is engine wore out (obviously it is to an extent), or something else?

I have a 2001 Ranger 4.0L 4x4 with 101,000 miles on it. I went to go get in it the other day and the Air Bag Light came on out of the blue. I've drove it some since and it is still on. The light blinks for about 1 minute upon startup and then stays on solid for the remainder of the trip. What would make this come on so suddenly and is there anything I can do/check?
