Ford F-150 - 1997-2003 :: Rough Shifting In Cold Weather
Dec 31, 2014
I have a 1999 Ford F-150 XLT, with the 5.4 and a 4spd auto. 172,XXX miles on the clock and i have owned it starting on April of 2014.
Tonight driving home from work, it took some time on the highway (4 miles) to shift into top gear. When you lift off the gas pedal after reaching the speed limit, normally the truck will shift from 3rd to 4th no problem. When I let off the pedal, there was no gear change.
It took sometime for it to shift up. When downshifting on the exit ramp, there was nothing abnormal. Where I live it is 19 Degrees Fahrenheit and this is the beginning of the cold snap that will last well into mid-January of next year.

Have a 2001 F150 FX4x4 and since the weather changed and started having days below 40 the truck has started running rough for about the first 15-20 miles. When you first start it starts like normal for first 3-5 min and then it starts loping real bad like it has a cam in it!

A problem with having a 12 volt battery maintainer hooked up to your truck when not being used for a few weeks? In this cold weather the new battery keeps drawing down while not in use and is slow to turn over after 1 1/2 weeks or so? I think the maintainers charge at about 1.5 amps. I wonder if that can keep up with all the parasitic draws: PCM, radio presets & clock, remote door lock system, and factory security system and keep the battery topped off as well?
Also, is there any problem with putting a charge on a battery when the cables are still hooked up to the trucks electrical system with either a maintainer or a full size charger, Example: screwing up the PCM?

I have 1999, F150 5.4L with electric 4wd shift. I put it in 4high just fine and smooth. Now 4lo on other hand rough shift if it goes in 4lo, sometimes won't engage but 4 high works fine. What's the cause

I bought a 1997 f150 with 160l miles on it. It is a 4x4 with the 5.4 v automatic. While I'm drive and in 4th and 5th gear, the tranny shakes the whole truck and then shifts hard! I check the fluid and it's still good and red but looks like there is to much. I'm planning on removing some and adding some lucus additive in it. What could cause this???

I have a 94 Ford Crown Victoria with 180,000 miles. I got it from my grandmother in 2008. It's a great car a runs like a dream most of the time. Here's the problem though...for the past three summers, when the temperature outside gets above about 70 degrees, it starts giving me transmission problems. The shifting becomes rough, and it revs and jerks. It does this all summer and then when the weather cools off again it runs beautifully. Do I need a new transmission or is there something less expensive that I can do to fix this? Why does the transmission act up only in warm weather?

Rough shifts like my 99 GLS (93k mi.) suffers from. Why this would happen only in warm weather and stop and go driving and not when the outside temp is less than 60 degrees?

So I recently acquired a 2002 F-150 4x4 super crew with the 5.4 V-8. It idles rough (surging from 400 - 700 rpm) when cold, and sometimes dies, but more often then not it stays running. It runs and drives fine when the accelerator is pressed and when going down the road. When it gets up to operating temperature, and has been there for a while, it seems to idle fine 95% of the time. The codes I have are P0136 (bad circuit to O2 sensor), P1151 (HO2S detects lean mixture or something like that), and the infamous P0171 and P0174, which is lean exhaust/mixture on both banks. Now I have read extensively on the internet about these symptoms and have done the following:
Sprayed every vacuum hose with carb cleaner, and even around the intake manifold and injectors.
Considered the IAC (its new, the guy I bought it from replaced it a couple months ago) Torque app for android phone says vacuum is good. Cleaned the MAF and air temp. sensor with electrical cleaner Checked all of the vacuum hoses on the engine by pulling them off
Put grease around the fitting where the PVC valve attaches to the valve cover. Seemed to make it idle a lot better after messing with it, but I don't know if it was a result of the engine being fully warmed up, or my messing with the PVC.
What to try next? I'm close to just dissecting the top part of this engine and seeing what the intake manifold gasket looks like..or could it really be an 02 sensor?

When it's cold outside my car will start up, but not stay running. The only way I can get it to stay running is to keep my food on the gas for up to five minutes. Once the vehicle is warmed up, it stays running. If I start it every hour or so, it will run fine. It's just when it's been sitting out in around zero degree weather overnight for example.

my 2012 nissan sentra when I first start to drive it in the morning when the temperature is below-5C does not "shift" properly. At 40 km/hr it runs at 2400 rpm. I drove it this morning to work and the whole 2 km distance it ran at 2400 rmp. The dealer says that this is normal until the car warms up, which is strange as the car only started doing this in January of this year. Coming home at -6C , I drove it for 3 blocks, it ran at 2400 rpm at 40 km/hr. Stopped the car, shut it off, restarted it and then drove home with the transmission shifting properly and rpm down to about 1500 rpm at 40-50 km/hr. We normally were getting about 400 km per 40 liters of gas, now it is down to 200-300 per 40 liters of gas(for in town driving).

My 2005 Prius shifts into Neutral, "N", when I put it either into Drive, "D", or Reverse, "R", during Cold weather, mid 20's and below. It will only stay in "B" to drive, and I have to hold the shifter in "R" to back up or "D" to drive. After the car warms up while driving 15-20 minutes in "B", I can shift it into "D" and it will stay there. I normally start the car and let it warm up in the morning for 10-15 minutes on cold days, below 25F but still I'm only able to drive it in "B" until it's ready. I just moved to Montana after driving this car in normal Southern California driving conditions. It happened while vacationing in Montana during the winter of 2007 a few times but it didn't bother me since I wasn't living there. I reported to Toyota but they couldn't do anything since the weather wouldn't co-operate. This car is still under 70,000 miles.

2 questions regarding our 2001 F150 Supercrew. My 2 questions are:
My 2001 Ford F150 Supercrew (5.4L, 230,000 miles)has the check engine light on with the code reader telling me that it is the P0174. The truck would run rough when cold (usually in the mornings) and sometimes it would get close to stalling out when coming to a stop light. So we would quickly put it in park and give it some gas to rev it up a bit. After the truck gets warmed up, it runs great with no hint of the rough idle. Since this all started I have changed out the PCV valve and replaced the PCV hose (including the elbow). I have also replaced the Idle Air Control unit but that didn't really make a difference.
We then experienced a cylinder #4 misfire which we resolved by changing out the cop with a new Motorcraft unit. The misfire went away but we still had the problem of running rough at idle to the point of stalling out at stops when the engine is cold. A few weeks ago we cleaned the MAF sensor and that seemed to work. The truck doesn't run as rough now (when cold) at stop-lights, but occasionally it will still have the loping idle. We cleared the check engine code and it stayed off for about a week before returning.
I don't know what else to check other than trying to see if there is some type of vacuum leak, but I don't have access to a smoke machine nor would I know how or where to hook one up. Removing and cleaning the throttle body would work? What could be causing the trouble, or what I should do to further isolate or troubleshoot the problem? I saw a you-tube video on the F150 intake manifold gasket possibly being the problem and although I hope that isn't the trouble with my truck, if it is then I will have to deal with it. We need the truck to get to work and the car is now due for a registration renewal, but we can't get a California smog certificate with the check engine light on.

I have a 91 Miata Auto. I bought it from someone that (I think!) never drain auto trans fluid during its 145K mile life. So last year I replaced all the gaskets/filters and tuned up the car. It runs fine except shifting harsh in cold weather. I have to mention that it seem to have no power and goes very slow on first few minutes.I used a pump to suck trans fluid out. It was so dark (even I dropped the trans pan and replaced filter/gasket). Then I pumped Lucas trans fix fluid in and it seem to improve. What should I do more to reduce the harsh shift condition in cold weather? Or is there a booster module need to be replaced?

2000 Sierra 1500, 5.3L engine. When he starts it in the cold (below 40 degrees) at first hits 1000rpm, then immediately drops to 400-500rpm. The idle is rough and wants to die if he tries to drive it. However after 10-15 minutes and the eng warms up, its fine no problems at all. There is no codes, so the scanner we had didn't tell us anything. He had cleaned the TB and intake system with cleaner, no dice. He also disconnected the IAC while it was idling rough, that didn't change the way it ran at all. We would like to toubleshoot it more before we start throwing parts at it.

My idle seems to always be somewhat rough whenever I put the heat on in cold weather. While in drive I'll come to a red light, heat will be on and I'll stop. The. my idle will bounce down then back up. I shut heat off to test and it only does it while heats on.

I have a 2001 Toyota Sienna xle that started running rough when the weather turned cold. When started, the car idles very high and will not shift properly until it was been running for around 5 minutes. After that it will run well for about 10-15 minutes and then begin to run rough or poorly. The problem is very noticeable at low speeds and when stopped. It never actually kills, but it feels like it is going to. At high speeds it is less noticeable but occasionally you will feel it jerk or chug like the transmission is slipping or a belt or something.
I took it to a mechanic who checked the codes and found that the ignition coils were supposedly bad. I say supposedly because they replace three of the ignition coils and the problem still persists. I then took it back to the mechanic who then told me it was the oxygen sensor. The o2 sensor was replaced and the problem is still there with no noticeable improvement. I again to it back to the mechanic who tells me that they scratching their heads.
I have done some looking around on the internet and have found some discussions that seem to have some promising leeds and actually last weeks car talk show had a caller who described a similar problem. The guys told him it could be a oxygen sensor but they thought a better possibility would be EGR valve or a vacuum leak. Not sure if this sienna has an EGR, but I plan to suggest looking into it to the mechanic. Also, I found some discussions talking about the idle control valve and the engine control module.

I have an 1997 F150/4.2 V6/220,000 miles/4x2. During hot weather (over 90F) the engine slowly overheats. While driving on the interstate (from Indy to Fort Wayne), the coolant temperature shows normal on the gauge. Slowly the temperature gauge creeps up to close to the red area. I am running the A/C.
When I switch the heater on and the heater fan at max, the temperature gauge drops pretty quickly to a normal range. I switch off the heater and the A/C back on, then it takes 30 minutes for the temperature gauge to start rising again.
When I open the hood when the gauge shows close to the red area, the upper coolant hose has a lot of pressure (can not squeeze it), which would mean that the thermostat is open and the water pump is working. Also the fan is running fast.
The coolant was changed out a few weeks ago and the coolant level is at normal level when the engine is cold. At lower ambient temperatures, there is no overheating. I am puzzled what the problem can be. I am thinking of a restricted coolant flow.

I have 3,500 miles on my RWD '14 F Sport. I have been noticing since its been getting colder, that the transmission is jerky for about the first 5 miles of my morning drive. It's like that even if I let my car warm up for a minute, instead of just taking off right when I start it. It's a lot more hesitant to downshift one gear for an incline. And when it does, it's slow, sloppy and then clunks.

Does the 2002 7.3 have an automatic high idle in cold weather?When you start it after it runs for a few moments it goes into high idle until you hit the accelerator. I had a 96 powerstroke before this one,it didn't do this. Just wondering?

Ok I've been getting a intermittent misfire on my truck for soem time now. It ran great all winter but now its getting hotter it intermittently misses. Last summer I replaced all the coils. And the coil inquestion now was replaced since last summer with Motor Craft Coil. I have red the check Engine Codes a d here is the freeze Fram data
DTC :P0351
Fuel System I : Closed Loop
Calculated Load: 71.37%
Engine Coolent temp: 199.4 F
Short Term Fuel Trim Bank 1 : 3.91%
Long Term Fuel Trim Bank 1: 0.78%
Short term Fuel Trim Bank 2: 6.25%
Long Term Fuel Trim Bank 2: 0.78%
Engine RPM :1613.25
Vehicle Speed Sensor: 4.35 MPH
What might be my problem? Since The Short Tem Fuel trim from bank 1 and Bank two are vastly different could that mean my fuel injector is not working correctly?

I have the LED mod and several weeks ago, my LED stopped indicating and the truck would not start in cold weather unless I jumped the terminal on the relay. I replaced the relay and while I was tightening one of the small lugs, the one towards the nose of the truck, I felt it break.
The truck acted just like it had been for the weeks prior, if I didn't jump the relay, it wouldn't cold start, so I assumed, because I had broken that small lug, it wasn't getting the signal to turn them on.
So what now? obviously the GP's themselves are working, as the truck starts when I jump them. But for some reason no signal is getting to the relay. What do I need to check to see what is going on between the PCM and the relay?
