Ford - Explorer :: 2002 4L V6 Is Running Rough
My 2002 Ford Explorer 4L V6 is running rough I found out why I just don't know what the piece is called because I need a replacement. Mine fell off and fell down the engine and melted quite a bit. Also the part number on my piece doesn't work anywhere, that I have typed it in. Mine has a Ford part number of 1L2U-9F764-AC. Also need to know the proper Ford number. I have a picture I found online with an arrow pointing to the piece I need.
View 1 RepliesSierra :: 4.3L Running Rough When Cold - Engine Is Missing
We have been having issues with my son's 97 Sierra running rough when it is cold/damp. It feels like the engine is missing.
Today, which is warm and dry, it started running really bad and it was all he could do to limp it home. It seemed like it wanted to idle fine but when he tried to rev it up the tach would start jumping and it seemed like it was missing.
Could this be a bad cap/rotor? The engine has 200,000 miles and we've never changed the cap/rotor. I changed the plugs/wires probably 100,000 miles ago.
Ford - Explorer :: 2004 - Rough Idle Like Missing And Die Intermittently
I have a weird intermittent problem. Sometimes when I start my explorer it will idle down and die immediately, I restart and it will idle about 400-600 really rough, sounds like it is missing. When I drive it it is jerky and the acceleration is sluggish but after I get it up to about 20 mph it clears out and then drives and idles fine until I shut it down. Plus these things only happen about every third time (on average) that I drive it. Lastly it's not giving me any codes. What this could be?
View 2 RepliesFord F-150 - 1997-2003 :: 2002 - Running Rough And Check Engine Light On
My girlfriend has a 2002 F-150 with the 4.6 V8 and I was going to change the spark plugs for her. She said it started running rough and it threw a code and check engine light. She took it for a scan and they told her the number 5 plug was mis-firing. I'm fairly handy and bought a set of the recommended Motorcraft plugs from Rock Auto, AGSF32PM. It also matched the number in the owners manual so I thought I was pretty safe.
Funny thing, when I took the old ones out, they were AGSF22WM's instead. My thinking is they are a colder plug than the supposedly original equipment, but I don't think they've been changed before. They looked well used but the color was good. The truck has about 135K on it.
Long story short, and to get to the question(s), Would there be any reason the factory would have put a different plug in the engine than what is listed? Am I asking for trouble going with a hotter plug than what's been in there (pinging or timing retardation/loss of power)? Am I just overthinking the whole thing and need to put it back together and drive it?
Ford Ranger / B-Series :: 1999 - Running Rough / Missing And Surging At 50 To 70?
I live in Kansas and was home in Georgia for the last 2 weeks. The truck drove great there after a fuel up started missing and surging at 50 to 70 thought it might have been bad fuel. waited till it was low added Lucas fuel treatment and premium gas still was doing it. no check engine light. went to Advance and fuse for light was blown they checked and was getting mass air flow code. unplugged it and seemed to be better, not perfect but better. plugged it back in and went to do it again. Changed mass air flow night before the drive back to Kansas. Ran well from Savannah to north Georgia then started doing it again the rest of the way home. Going to have advance check code again.

The truck always ran perfect till two days ago. went to start it in the middle of the day , it would barely start, when it did it was missing bad. then seemed to clear up a little after about 30 seconds but still missing. they thought they got some bad fuel. so they dropped the tank cleaned it all out and got new fuel, no change.
Him and a so called mechanic "kid from fire stone" played around switching coil packs around from the injectors with no change. He tells me that the two front cylinders , one on each side are not firing. that those two spark plugs are coming out fuel soaked after running the truck. He thinks it dropped a lifter or push rod popped out of place.
I took my A/E over and came up with codes p0106 - map sensor, and p0135 - 02 sensor. i cleared them and started the truck, shut it back off ran codes again. He also said they pulled the 02 sensor and it still ran the same.
Ford Super Duty (1999-2016) :: 2002 F250 - Engine Running Rough And Vibrating
I have an 02 f250 5.4. I just did the intake manifold. I also changed the spark plugs and the valve cover gasket. Following this I drained the oil and filled it with fresh oil.
It started right up but it felt like the engine was really vibrating and running rough. The check engine light than came on. I don't have one of those tools to diagnose it.
What could be wrong?
Ford - Explorer :: 2002 XLT - Missing Plug On Bottom Of Transmission?
I just had my tork converter and flex plate replaced on my 2002 Explorer XLT, it has the v8 with 5 speed auto trans. My question is this : on the bottom of the bell housing under the tork converter is a round hole aprox 1 1/2 or 2 inches in diameter. Should there be a plug or cover of some sore to keed dirt and debri from getting in ?
View 4 RepliesFord 6.0L Power Stroke Diesel :: 2005 Missing / Truck Started Running Rough
So I have been fighting a rough running, missing problem. My truck started running rough one day on the way home. I got it scanned, it showed injector contribution balance 1&2. Made sense to me that it threw those codes. I replaced 1 and 2 with oem replacements. Got that all done, truck still ran like crap. I changed fuel filter with motorcraft ones and drained the water separator. That didn't work. I am getting it scanned again, so i will have codes shortly.
Also, for a while it would run with absolute no problem. It was intermittent like that. Run bad run bad run bad and then one day run flawlessly. I though it was electrical. Checked all the common places for chaffing, saw nothing. Even did the wiggle test while it was running, no change. But it hasn't been intermittent for a while now.
Ford - Explorer :: 2002 - Missing At 90k Miles - Noise From Intake Area?
The other day my 2002 Sport Trac with 4.0 started to miss badly. It has only about 90,000 miles on it. It started to do this suddenly from one turn of the key to the next. It also makes a weird noice that sounds as if its coming from the intake area that can be described as a "chuffing" sound thats in time with the engine. The intake also gets very warm to the touch. We have since stopped driving it. I sprayed carb cleaner all around where the intake meets the head with no change in rpm. I also checked the plastic hose that goes behind the engine to the pcv valve and its ok.

I have a 1972 MG midget and recently rebuilt the carbs, (needles&seats, floats, needles&jets, new fuel pump&filter) along with ignition,(points, condenser, rotor and plugs), checked timing and adjusted the valves. After tuning and balancing the carbs I take it for a test drive, it runs perfectly for about 5 - 7 miles then starts missing and running rough. I thought this might be heat related so I ran on a cold day with no change. I also put in my old coil with no change. After 25 years this is the first time I have been stumped.

So, I have a 2007 f250 with the 6.0. When she's cold she starts fine but runs rough like she has a miss. When she warms up the miss goes away and it runs pretty good. But if I shut it off it won't start for about an hour or so.
ICP sensor has been replaced.

Ford 6.0L Power Stroke Diesel :: Rough Running Like Missing When Cold / Puffs Of Blue Smoke From Tail Pipe
My truck has been having this issue pretty much since I have had it, but it seems to be getting worse, or so I think.
When the truck is cold, it does not want to move very well. Like it's missing, and it does this until it gets warmer. Also, I have puffs of blue smoke come out the tailpipe when this occurs with it cold.
Injectors? Injector o-rings? Stiction?
FICM volts are good at 46.5v-48v when cranking.
Passat (B5) :: 2002 Running Rough And Yellow Engine Light Blinking Then Turned Off
Drove fairly fast (160km/hr or 100 miles/hr) then took an exit down a ramp and had to stop at a red light. Noticed all of a sudden that the engine was running bit rougher and then noticed the yellow engine light blinking. I know to turn off the engine immediately when this occurs but then all of a sudden engine light turned off and car was running smooth again.
Car has been reliable for 7 years - proper maintained, synthetic oil, 171000km, timing belt changed, burns very little oil, good torque. Should I have it checked by the dealer (fantastic fair vw dealer)?
Ford - Explorer :: Running Rough When Takeoff From Idle Until Hit 25 - 30 MPH
My explorer has been running a little rough, particularly at idle. When I take off from a rough idle, it'll run rough until I hit 25-30mph. I ran by O'Reilly's hoping to pick up a pack of spark plugs and be done with it, ended up leaving with a new MAF sensor. It ran better for about 10 miles (I'm a delivery driver, so I did a lot of stop and go immediately), before it ran even worse than it did before, but at least my CEL finally came on. Took it back to O'Reilly's and they read a MAF sensor code and a catalytic system code (didn't ask for the codes, and now realize that was a mistake).
So today I took it to a muffler shop to have the catalytic system diagnosed. They looked at it for 10 minutes and told me they didn't think it was the converter. They said it seemed more like the EGR valve or solenoid, or the IAC. He scanned the codes again and got multiple "running lean" codes (0171, 0174, etc). The guy said I didn't have a vacuum leak, so I think I can rule that out. Unfortunately, the truck idled fine the whole time so he didn't feel comfortable giving me a definitive answer. He told to to leave the EGR valve hose unplugged for a few days and see if anything changes. I'm thinking about running a bottle of fuel cleaner through it or taking off the IAC and/or EGR and cleaning them myself.
Ford - Explorer :: 2003 - Suddenly Started Running Really Rough

View 11 RepliesFord - Explorer :: 1993 - Intermittently Started Running Very Rough
I have a 93 Ford Explorer, manual transmission. About a month ago it intermittently started running very rough. I does this wether the weather is rainy or not. The engine has done this when it just started up, cold, and when it's been fully warmed up. I have been able to drive it, but it has been quite a challenge. When running, there is a very noticeable noxious exhaust smell. The check engine light has come on some of the time. When the eec codes were checked it only revealed 522, the car wasn't in park or neutral when running the test.
I have tried clearing and rerunning this test several times, yet 522 still shows up. No other fault codes. Don't know how this would cause engine to perform so bad. The fuel tank has been near full when it happened so I believe the gas to be good/ no water. The engine has a lot of mileage on it, over 200K, so I'm not sure if something inside could be malfunctioning, but don't know how to check. The car will run for days very smoothly before this happens again. I have changed plugs, wires and the pcv valve and it still occurs. It's like the engine is hitting on one cylinder when it happens.

I have a 2000 ford explorer. 4x4 v6. One day i started it up and it was running rough. It had real sluggish power. Then the check engine light came on. I hooked it up to the code machine. The only readout was number 3 misfired. I replaced the plug and all was fine. A few months it happend again. I replaced it again and it was fine. Well it just happened again. I replaced it again. It ran good to work but on the way back no good. Light came on again. Hooked up the machine it read number 4 misfired and number 2 bank lean. So I replaced number 4. It still runs like shit rough idle and no power. Give it gas it dogs out but then it'll kick in if i get on it. Thinking it maybe a vaccum leak or intake leak or o-rings.
