Ford F-150 (2004-2008) :: 2005 - Smoking White - Got Codes P0174 / P0300 / P0305 / P0306 / P0316?
Sep 23, 2014
05 2 wheel drive f150xl 4.2 l 135,000 miles. Smoking white out of exhaust. More at start up but doesn't go away. Turns a little blue. When parked at idle if I bring up the RPM's quick I will get a little puff of black in the white smoke. I can't smell or taste(when I touch my fingers to mouth) any anti freeze in the exhaust smoke but I live in Myrtle Beach and I have little if any anti freeze in the coolant. I flushed the motor, changed oil and filter and added a can of seafoam. I took the throttle body off and cleaned it. I also replaced the air filter because I went down a dirt road and hit a deep water hole. Dirt and mud got into the air filter and by passed it also. This was the reason for the engine flush also. I can't recall any smoke before this. Maybe a puff on start up from moisture not sure. Im going to buy a coil pack and plugs and start from there. I have never had this many codes.
P0174 Bank system 2 to lean P0300 random multipl Lean mil. Missfire detected P0305 random multiple Missfire detected cylinder 5 misfire P0306 cylinder 6 Missfire P0316 Missfire detected on start up first 1000 revolution

I am having the above codes come up P0316 and PO305. The car is running rough...just started tonight. The check engine light started flashing but it's on continuously. Of course when I had the codes read at a Firestone they gave absolutely no support as to what it could be.

I have a small problem that has been going on for about the last 6 months. It only appears once in a while, and only when I have parked facing uphill for longer than a day or so. Upon first start (cold) after sitting pointed uphill for a day or two, it starts real rough and sputters a bit. Then when I check codes, I always have a pending P0316 (misfire within the first 1000 revolutions) along with a P0306 or P0301. No dash lights or anything.
Since those two cylinders are at the front of the motor, could it be that the fuel is leaking back down the rail and leaving those two injectors dry? It isn't always both cylinders, sometimes one or the other. If this is the sign of something bigger on the horizon, I would like to have a heads up.

I have a 1999 4x2 F150 XL, 4.2L engine, 5-speed trans., about 197,600 miles and have been getting P0306 and P0174 codes. The check engine light came on and stayed on. Also, pretty much randomly, my engine over-heats and the engine compartment coolant reservoir is suddenly dry as a bone. I bought the truck new and this has only happened twice, during normal driving.
Clearing the 0306 and 0174 codes. Not sure what to do about the over-heating thing.. What I've done so far to try to clear the codes is the least expensive stuff:
=> Replaced both forward O2 sensors, have read where the two rear O2 sensors don't necessarily need to be replaced so I haven't replaced them yet. The sensors that came off are Bosch, as are the ones that I bought from Autozone and installed.
=> Replaced old spark plugs with Motorcraft brand, gapped to 0.054 in.
=> Replaced old spark plug wires with Motorcraft spark plug wires.
=> Cleaned the MAF sensor
=> Replaced PCV valve and replaced an section of elbow hose near it. The original elbow had a big hole right at the 90-degree bend, on the inside.
=> Replaced a cracked, dried-out, vacuum hose coming from the evap cannister purge valve and going to the front underside of the upper intake manifold.
=> replaced fuel filter.
After doing all this, I took it out on the road long enough for the computer to wake up and relearn and got the check-engine light again. Only this time it was flashing. I gather from reading in this forum that a flashing CEL is worse than a constant-on CEL so I drove back home and have yet to take it back out.
After reading about problematic ignition coils, I followed a procedure in my Haynes manual to check mine out:
=> Verified the correct resistance values at the electrical connector (0.7 ohms),
=> Verified battery voltage is present at the harness side of the electrical connector (about 12.6 volts),
=> checked the resistance values between the three sets of 'towers'. Starting from front to back, the resistance readings were 13.06 kOhms, 13.12 kOhms, and 12.98 kOhms. The correct range in the Haynes book is 6.5 to 11.5 kOhms so I thought maybe my ignition coil was bad.
I located a Motorcraft ignition coil at a local O'Reilly Auto Parts store, went there, and was able to check the resistance values on that new one. Turns out the resistance on the new one at the parts store is pretty much the same as that on the one on my truck (all three coils were 13.something kOhms), so I haven't replaced the ignition coil. I guess either my Haynes book is probably incorrect or the ignition coil on my particular F150 has different resistance values than the rest of the vehicles covered by that manual.
Next things I'm looking at replacing:
=> egr valve and the associated line to the DPFE sensor. (DPFE replaced a few years back, as a result of a P0401 code)
=> iac valve
=> upper intake plenum gaskets
I'm kind of at a loss at this point. I hate to just continue replacing things without knowing that I'm replacing the right things.

So i got two codes.... P0300 and P0305. I am thinking its the coilpacks because i changed the spark plugs a few months ago. Cleared it last week and came back today. What else could it be? And is it ok to just change one coil pack or do i have to do all of them? The recall was done in 2007.

I have a 2005 F-150 5.4L 2WD 90K miles. I started getting a misfire and hard jerk when going uphill. No codes for a few days but misfire got a little worse and more jerking at full throttle acceleration or level throttle up a hill got codes p0300 and p0171. I replaced the fuel filter cleaned MAF and changed plugs Motorcraft plugs (none of them broke during replacement). Miss got worse. Missing at idle and no power 3K rmp to get to 40. Only code pulled was p0171. Replaced upstream O2 sensors and COPs. Will barely idle now. Dies when put in gear. Full throttle barely moves forward a few feet just sputters. Checked vacuum lines cannot find anything. Only code I get is P0171. Fuel injectors next? Or shop?

My 04 F-150 has recently been blowing these two codes. I've replaced the coil pack already and it is still making the check engine line come off. Just put some injector cleaner in the tank last night, so that might take a while to work through. What I should be looking for?

I have a 2000 Toyota Avalon XLS with 134k miles, engine is a v6 (3.0). It has a rough idle and a steady misfire. You can drive it sometimes and it will run perfect and you can drive it sometimes and it will misfire. I am getting codes P1150, P0300,P0302, P0304,P0306. Driving me nuts.

I have a very Big problem with my Ford Escape 2002 I have this problems code: P0305 accuses Cylinder #5 P0306 accuses Cylinder #6.
I already change the gasket i buy the felpro Kit, and i Also replace all the sparks and spark plug boots, I clean the air sensors and i also replace the EGR, i try to switch cables, and all is the same the car start buy when i accelerate it just go off, i don't know what can i do next, somebody told me to change the fuel injector, i take the pressure in both spark holes the number 4 was 150 and the 5 and 6 was 120, No leaks oil. My car is a Ford Escape 2002, XLT 3.0 4x4

Just recently replaced the driver side 4wd actuator. When testing the system to see if it was working, I noticed that in 2wd everything seemed to be in order (wheel spun without the half shaft, no grinding noises on test drive, seemed good to go).
However, when I switched to 4hi, the dash light "4HI" would come on but the wheel still spun freely without the half shaft. When the truck was off, the wheel and half shaft spun together as they should when vacuum is released from the actuator. When I switched to 4lo, the dash light did not come on and the check engine light came on. Pulling codes revealed P0171 and P0174.
Could these codes be caused by a bad solenoid? Is the solenoid not switching the vacuum off and that's my issue? Are there other possibilities?

My son just left. We scanned his truck and got these codes.
P0172 Bank 1 rich P0300 random misfires P0303 cylinder 3 misfires.
I used the Torque APP Pro to check these codes. I went to live readings in the Torque APP and saw some readings for Long term and Short term bank 1 Readings.
They are all "greek" to me, and I don't recall what they were, but could get those readings tomorrow.
When I have done searches combining these codes together, I see changing spark plugs. P0172 alone gets me a different train of thought. Mainly CAT issues.
Also, his cranking to start is quite long. (A lot longer than my 6.0L would ever think of cranking) At least nearly 30 seconds of cranking. We are leaning toward first just changing #3 plug.

Here is my situation : I have a F150 1999 4x4 ext cab with 326 000 km. A little while ago I got a P0401 code so I decide to clean the TB first and at the same time change plugs and wires since they were overdue. The same code came back and a misfire. Ordered EGR valve, DPFE sensor and selenoid. Realize that I had ordered crappy plugs by mistake. I change all plugs. Had to wait for the EGR valve and others to arrive. I drove the truck for a while since I did not have the time to change the valve and others, during that time the misfire did not come back. Yesterday I change the EGR and others. Today I get a truck that runs really rough and got new codes , P0305 and P0174. I'm really confused now on what should be my next step, should I change the coils, can a P0305 cause a P0174. Should I change vacuum hose going to the EGR , selenoid and DPFE.

I love my Ranger. I'm quite impressed with the power and durability. I'm ticked at Ford for stopping production.
I have searched my problem and could not quite narrow it down. I have also tried several remedies with no improvement. I need to narrow it down to a specific item.
2004 Ranger, 4.0 liter, 4x4, 131,000 miles, runs great above idle.
Problem: rough idle, idles at about 750 rpm's. If i raise the rpm's to 850 and up, smooth as silk.
The truck did this a few years back. Not quite as rough and it went away by itself.
Engine light came on this time with P0303 & P0316 codes. I have replaced: plugs, wires, coil pack. I know that the #3 plug is sparking quite well. the #3 injector is getting signal to spray not sure if it is. I have 4 O2 sensors and I believe I tested them correctly (passed). The passenger side upstream or pre cat sensor has not been tested yet. Had to rent a tool and will do that in morning. I slid a piece of aluminum roof flashing between the crank position sensor and the crank pulley. Not a noticeable difference. While at idle (750 rpm's) I pulled each (#3,2,1,) (one at a time) injector wire plugs off the injectors. No noticeable difference. I pulled the vacuum line off the egg and operated it with a vacuum tool. Seems to be working fine. Sprayed carb cleaner around on vac lines. No engine surge

Our 2007 Avalon with 65xxx miles on it was skipping and running rough this morning. Running a scan with my VAG-COM gave me these codes.
Mode 07: Pending emission related fault codes Address 7E8: 2 Faults Found: P0305 - Cylinder 5: Misfire Detected P0355 - Ignition Control Circuit for Cylinder 5: Malfunction
Would you say it is time to replace the Coil for this cylinder, or should I do more troubleshooting first?
From what I've read on this forum, it appears cylinders 1, 3 & 5 are at the rear of the engine and are a PITA to change. Is there a good write-up or video on how to change these at the rear of the engine?

My 2005 f250 5.4 with codes p0171 and p0174. I have replaced fuel filter, MAF, Checked for vac leaks by smoke and water test.
I don't have a way to check fuel pressure on this thing since it must have been to much trouble to put that test port on the fuel rail!!!

Went to do a few things this morning, started the car and it ran like crap. It was an obvious multi cylinder misfire. I checked to make sure all the coil connections and all other visible connectors were tight. Went back around and noticed the mil was flashing, so I shut it down and took the girl's car. I returned later in the afternoon and swapped out my intake in anticipation of it going to the dealer. Started up the car afterward and it ran fine without the mil lit. I had the codes pulled:
p0300 p0303 p0306 Its kind of weird that 2 coils would go at the same time. Do these cylinders share a coil or fuel injector driver off the ecm?

Well my problem went from bad to worse. My 05 started running rough at idle, then smoothed out a bit but started smoking on acceleration a little. At this point it felt like it had more power than ever before and even ran smoother running up to 3k RPM before shifting (manual transmission). But now it's smoking so bad, I can't really drive it. It's smoking white or gray at idle but blowing black smoke on acceleration. I had a cylinder 5 contribution code but with the amount of smoke it's hard to believe only one injector is a problem. I pulled the EGR valve and it doesn't look stuck open but I'm going to replace it anyway.

My Suzuki has been in and out of maybe 5 shops in attempts to fix engine codes P0171 (system lean) and P0174 (bank 1 rich). None of them have successfully done so. I tried to take it into a dealer, but I was informed that diagnostic would take several hours (maybe $1000), and that the fix may be another ~$1500-2000, even though I have already replaced many parts related to these codes.
The dealer advised me to give up on the car, as the repairs could easily exceed the value of the car. I don't really care about that, I just need a reliable car that works.

I just did an oil change at my vocational school on my grandpas car, 2008 LE V6. On the way back it threw a CEL. Codes are listed in the title. Now googling those codes i found info on other car manufacturers i.e ford, dodge etc.. But i found nothing in regards to a gen 6 camry. It seems like this code has something to do with the engine running lean. Bank 1 and bank 2. What could cause these codes and what could be a possible remedy. P0174 and P0171 were both pending and setting a cel don't know if maybe they were pending before i did the oil change.

Friend has a 2006 with the 4.6 motor. From time to time he gets a random misfire code ( I think its 0316).. He claims it will only do it when the gas tank is less that half full. I don't see any correlation between fuel level and the code. I am going to check fuel trim values, etc, when the code is set, this weekend.... all I can assume is low fuel pressure which sets the code... Any problem with the pressure module or fuel pump / discharge hose that is related to low level in the tank ?
