Ford Ranger / B-Series :: Runs Rough For About A Minute After Engine Started When Cold

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.

Ford Super Duty (1999-2016) :: F350 - Engine Surge / Crashed?

I was recently involved in a fender bender. As I backed out of a parking space, I struck another vehicle. When I immediately attempted to pull back into the parking space to check things out, the engine in the F350 bus surged to the point that it crashed into one of the safety poles in the parking lot despite the fact that I had both feet on the brake pedal. The vehicle is 8 years old and has 25K miles (not used frequently) but never had this issue before. Could the crash have something to do with the vehicle's computer and the subsequent surge?

Ford Ranger / B-Series :: Idle Surge On Startup

On startup, hot or cold, I get an initial high idle, up to around 1800 rpm's. This happens immediately when engine starts, and then idles right down. This has done this since new in '04. Dealer at that time said it was normal and not to worry. It's always made me wonder, but I trusted the dealer. Ya, not always smart.

After 92k miles. Engine runs fine otherwise, but I don't really care for grabbing a bunch of rpm's on any engine without having the oil pressure up to normal.

A few weeks ago, I started it up, and some yahoo said he knew I drove big trucks by the way I started my Ranger. That was one of those times. I'm thinking IAC is wide open maybe?

Ford 7.3L Power Stroke (1999-2003) :: Intermittent Engine Light / Momentary Surge At Highway Speeds

I have a 1999 F350 200,000 miles. Now getting an intermittent engine light. Still runs well, although once or twice I felt a momentary surge at highway speeds. The light is on intermittently about 1/2 time. I read the codes and the following codes, as in the thread title, came up:

P0280 - ICP circuit out of range - low
P0113 - intake air temp sensor circuit - high input
P0470 - Exhaust back pressure sensor circuit malfunction
P0478 - Exhaust pressure control valve - high input

What would make these all code at the same time? Would these not make a noticeable problem driving? And how do I resolve these?

Civic - Honda :: 1999 - Engine Shut Off Within A Minute Of Turning The Car On

I have a 1999 honda civic that has had an issue with randomly shutting off lately. It always happens within a minute of me turning the car on and I usually have to wait several minutes before the car will crank again. When it does the engine shuts off and all lights immediately go off. Once I finally do get the car to crank its hit or miss if it will stay running, but if it makes it through the first minute or so its usually golden. Its like it has to have a perfect connection or something or it wont stay on. The only suggestion I've had from someone is possibly the ignition being bad.

Ford Ranger / B-Series :: 2001 - Airbag Light Blinks For About 1 Minute Upon Startup And Then Stays On Solid?

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?

Ford Excursion :: 2001 - Engine Surge When Cruise Set At 70 Mph?

2001 V10 115K miles

When I set the cruise dead on 70mph, the engine surges as if it's not getting fuel. I can set it at 68 and 72 and it runs great. Fuel filter was replaced 2K miles ago, and I just had new plugs put in, but it still does the surge thing. The RPM's don't bounce when it does it, but it the whole X lurches pretty good.

I'm not an engine guy so don't know what else to look for.

Ford 7.3L Power Stroke (1999-2003) :: Surge During Hill Climbing

Decided to try a new wheel to see if I can stop the surge during hill climbing with our 5er. Old wheel looked great with no dusting or nicks. New wheel sure has a whirl when it spools up, but sounds cool. Haven't pulled trailer since swap yet. Truck still only has 85k on the clock.

Ford F-150 - 1997-2003 :: Engine Vibrates Severely At Startup In The Morning For A Minute Or Two During Idle

2003 F150 5.4L Tow Package 140k miles... Had coils, all plugs/wires replaced two years ago due to vibe climbing hills. Now at startup in the morning for a minute or two during idle, the engine vibrates severely then subsides and runs fine rest of day. Doesn't do this every morning. Truck lives in FL. The issue is either temperature related or moisture related. Ford service has the truck presently and attempting to diagnose from an overnight stay. They already 'fixed' the problem last week by replacing #1 plug/wire and resetting the power control module (pcm) but two days later the problem came back. Tech said today that the plugs currently installed are Bosch (any issue with these plugs?)

Ford 7.3L Power Stroke (1999-2003) :: Hesitate For A Minute And Then Lag When Floor It Going Uphill

I have a 2000 7.3 and I have a hypertech Max Energy Programmer set to stage 3 in my truck right now (100 HP). I noticed last night when I was going up hill and had my foot to the floor the truck would hesitate for a minute and then lag before it was would catch up to itself. I did it again on some flat ground and noticed when it did do that my boost gauge would get to 20 and then fall to Zero. If I start out and gradually get to the floor without punching it the truck drive fine. How to fix it?

Ford F-150 - 1997-2003 :: 1999 4X4 - Intermittent Misfire / Runs Rough For About A Minute

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.

Ford Super Duty (1999-2016) :: 2003 F250 - Surge / Lag When Shifting

I just got 03 f250 with 6.0 and when shifting has a weird surge/lag thing happening. Reminds me a little of the old 7.3 surge when it was just started on a cold day. Seems to be worse in higher gears.

Ford Super Duty (1999-2016) :: F250 - RPMs Surge When Let Off The Gas While Driving

I've got a 99 f250 5.4 that runs like a top. In the last 6 months I've been chasing a little problem. It doesn't happen all the time but seem to be happen more and more. While driving any speed If I let off the gas the RPM's hold at around 1500 then surges down to 1000 then back up again to 1500.

Does that 2 to 4 times then all good. Give it gas again it does it again. It kind of does it when it wants. Could be fine for a trip around then next trip it acts up again. Checked a lot of the vacuum lines, PVC valve and replaced the idle control next to the EGR valve. EGR is next.

Idles and runs fine except the surge thing..

P0401 code as well.

Ford 7.3L Power Stroke (1999-2003) :: High Idle After It Sits About A Minute Warming Up

I have noticed thru the cold months after I start my 2001 F250 7.3L 4X4 after it sits about a minute "warming up" that it goes into a high idle. The high idle will stop once I press the brakes. Is this normal?

I think this is a unrelated issue, but just started over the weekend. Was riding home, and pressed my brakes and the pedal moved almost to the floor. Not normal conditions for my truck. Usually the pedal is very stiff. I have noticed that my power steering pump has had a hum for months. I changed the fluid (ATF Mercon) within the last 6k miles and that calmed it down a bit.

After the pedal went to the floor, the hum seemed to quieten down even more. The power steering still works and the reservoir has adequate fluid and so does the brake fluid reservoir. I haven't noticed any leaks around the truck. I'm going to bleed the brake in an hour or so. The brakes pedal seems stiff when I press it after the high idle, but then it gets soft after a pump or two.
