Ford F-150 - 1997-2003 :: Codes P0302 And P0401 / Misfire Due To A Loose Injector Plug
My 97 F150 4.6 4x4 threw a P0302 and P0401 the other day, I traced the miss fire to a loose injector plug. I reset the codes last weekend, I got in the truck and went to the Dump and to town to pick some stuff up. It threw the EGR code again, so this morning I did a little checking on the EGR I cranked the truck and disconnected the FPR vacuum line and hooked it to the EGR valve and the truck died down but didn't completely die.
Now the green line that went to the EGR valve felt like it had a slight bit of pressure coming from it. Is this normal? I did pull the white feed line from the EGR Regulator and it had good vacuum.
The regulator also makes a humming sound when you cut the truck off. Ill be pulling the alternator this weekend due to it going out last night, while I'm in there if Ive got to pull the throttle body id rather do it while I'm elbow deep in it. So does it sound more like a Clogged Throttle body or a Faulty sensor?
Ford F-150 (2004-2008) :: 2005 - Smoking White - Got Codes P0174 / P0300 / P0305 / P0306 / P0316?
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.

Ford F-150 (2004-2008) :: 2005 - Injector Stuck Open - Shake Really Bad - Got Codes?
Well I believe I finally had the opportunity to experience the wide open injector issue. I was driving to work and all of a sudden at a stop light my truck started shaking bad. It went away but as I took off every so often it would shake. I thought it was a tire or front end component so I pulled over and just got overwhelmed with the smell of gas. I drove 30 miles back home and check engine light blinked the whole way and truck ran . Also wasted at least a 1/4 tank of gas and the a/c wouldn't blow cold air either. Hooked it up to read DTC codes and got P0172, P0300, P0303, P0304, P0316 and P2196.

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 filled up at the same fuel station I've filled up at for 6 months, never had a problem. I just bought a 6 liter and put some injector cleaner in on the last fill up. Ever since then, it's been running really rough and missing when cold, and even when it's warm if I really lay into it, it'll pop and sputter. The fuel in water lights been on since I bought it. I think I have a bad sensor, because it was running fine until I put that cleaner in. Since its been running rough I put in new fuel filters and drained the fuel water separator, which only had fuel in it. I don't really know what it could be, but I'm 99% sure it's an injector issue since it started only after I put fuel treatment in.

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

View 14 RepliesFord F-150 (2004-2008) :: 2006 - Random Misfire Code P0316
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 ?

I was out driving my brothers Escalade today and notice that it had a lot more power than the last time I'd driven it. When I asked him about it, he said that he poured a bottle of fuel injector cleaner in about 2 weeks ago but hadn't noticed any difference. We thought maybe it was because he drove it all the time. He let his wife drive it and she noticed the difference as well.
View 14 RepliesPrius (2004-09) :: 2006 - Got Codes P0301 And P0302 / Misfire At Low RPM?
This has been an ongoing issue with our 2006. We purchased the car about a year ago and have put on just over 8,000 miles. Rebuilt the battery pack and replaced the 12v battery. This is my wife's car and I have a 2005, so I have done some diagnostics, tuneup, and even swapped some parts between the two cars trying to narrow down the issues.
Only recently have codes been recorded. The car is has a noticeable misfire at low RPM. Here is what has happened up until now:
11/29/15 - replaced spark plugs - #1 was fouled so I swapped coils between cylinders 1 and 4
2/25/16 - replaced 12v battery with new battery
4/1/16 - P0300, P0301 codes were first recorded and reset to see if they came back
4/10/16 - swapped Integration Relay with my 2005 (part # 82641-47010). My 2005 ran poorly after the swap, so I put a used one in my 2005.
Ford F-150 - 1997-2003 :: Codes P0304 And P0316 - Lean Bank 1 And 2
2003 F150 v6 2wd 170k ... For a year I've only had codes P0171 and P0174 (lean bank 1 and 2). I was told it wouldn't hurt anything... I think now I should have taken care of it.
Anyway 3 weeks ago my truck started running a little rough. It was sputtering and had trouble getting up to speed, sometimes also the air switches from vent to defrost until switch gears and rpms go down. It gradually got a lot worse over 10 days while part was otw. A week ago i changed MAF and cleaned the black thing it's inside of. It started running better but still not good. I pulled my small trailer 2 days ago and it got worse after dropping the trailer.
Today checked codes at AZ and lean codes are gone and have p0304 (#4 misfire) and p0316 (crank sensor problem). Is this related.? Also Right before all the trouble I changed battery and alternator. Also i read online that MAF needed 2 weeks to relearn the way I drive to get correct gas/air ratio? Is that correct?
Also I read so many different things I needed to do during installation... Some say I need to turn key to the on position after unplugging old MAF then plug new one in... turn key to on position 10 times, Rev up engine, drive it rough for the first 2 minutes... etc. Is there a correct way to do it or is it vehicle specific?
Should I start by changing spark plugs and coils? The guy i bought it from and trust said he changed spark plugs right before I bought it. Will it ruin truck if I drive it? I've read so much but everyone says so much different things on the same topic. I'd what to start with or if this is related.
Ford F-150 - 1997-2003 :: Codes P1518 / P0316 / P0303 And P0136?
I have a 2003 F150 V6 4.2L, 171,000 miles on it. I have four codes on it.
#p1518
#p0316
#p0303
#p0136
I had a p1518 in november of 2012, had it repaired and its back. In the time that I had it repaired and it came back on (maybe a month and a half ago) I only drove the truck maybe 3000 miles, if that. Just curious if this particular part should have some kind of warranty either by the MFG or dealer since the dealer repaired it. Have a limited budget, trying to find out what I can fix on my own in a timely manner.
Mitsubishi - Galant :: 2004 - Check Engine Light Came On When Putting Gas Into Tank
I loaned my car to a friend for 2 days. While driving, she allowed it to run out of gas. The check engine light came on as soon as gas was put into the tank and has never gone off. I now need to get inspected, but afraid it will not pass. Someone said to put "Garanteed To Pass" in the gas tank. I have never had any problems with this car. I am the original owner, and I keep the oil changed and the filter clean. The car runs perfectly with 120K miles! What should I do?

My 2003 ford ranger 3.0 v6 is having a misfire on start up and it is located in the forth cylinder. Where to start to get rid of this problem. i have already changed all my plugs wires and even the coil pack cleaned out the maf and looked for possible leaks. the car shakes really bad at lights and the check engine light starts to flash. Need diagram of where all the cylinder numbers are at and maybe the firing order?
View 14 RepliesFord Escape / Hybrid :: Check Engine Light Only Comes On After Motor Is At Higher Rev - Codes P0304 And P0316
A couple of weeks ago I got a check engine light. Pulling the codes I saw that it was a p0304 and sometimes a p0316. The first time this happened I check the spark plug cables and one was loose (cycylinder 4). Then last week my fuel pump died. since then I have gotten the two codes on a somewhat continous basis. I replaced the plugs (needed to anyway) and the problem did not go away.
The odd thing is that the check engine light does not come on at idle. IT only comes on after the motor is at a higher rev. The replaced plugs looked pretty normal, but the cylinder 4 plug had some carbon deposits. I am currently running injector cleaner in the gas. I may go ahead and replace the plug wires since the current ones are high mileage and it is not an expensive fix.
Ford F-150 (2004-2008) :: 2006 V8 - OBD Error P0302 / Low RPM Torque Causes Major Shuddering
2006 F150, 4.6 V8 ... My truck was running fine until one morning I was sitting in the truck giving it my customary 30 second morning warm-up and it starting running very rough and quickly threw Check Engine LED.
I hooked up my laptop and got the following error codes: (To assist with future searches, the error codes are P0302, P0303, and P0353)
It seemed to drive fairly well, but low RPM torque causes major shuddering, so I try to keep the revs up to avoid damaging other components. The first step was to replace the spark plugs. They looked to be original and I'm at 140K on the truck, so it's probably time.
I went with Bosch Platinum as the factory plugs were platinum. When replacing the plugs, I moved the coil pack from cylinder 2 to cylinder 3 to determine if the problem would move. After the plug swap, the engine did run noticeably smoother (so the plugs worked overall), but still had the low rpm shudders and the same error codes (after clearing them).
Unfortunately, the error codes still indicate cylinder 2. I guess a misfire could be related to the fuel injector as well, not firing at the right time or not a complete spray, but what else could cause this?
Ford Excursion :: When Parked Facing Uphill Start Rough And Sputters - Codes P0316 / P0306 And P0301?
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.
Ford Excursion :: 2000 - Misfire - Got Codes P0301 And P0302?
2000 Ford Ex 5.4 V8 175K miles
Top of radiator (plastic part) had a small crack and started leaking on drivers side. Fixed with JB Weld. Ran fine for a day. Now I have a bad misfire and codes P0301 and P0302 (Cyl 1 and 2). Cleaned MAF and checked Air Filter. All good. Plugs replaced at dealer less than 20K miles ago.
So I took off Cyl 5 (easiest) and found that the boot is fine but the collar on the boot is done for. Can this cause the issue?
