Ford - Explorer :: 2002 V8 - Engine Running Rough - Seems Missing?

On my V8 02 XLT Explorer the engine is running rough like it's missing.

I think a coil may have gone bad,,found a LOT of anti-freeze down in the spark plug hole.

Have replaced the intake but now need to fix the roughness.

Is there any easy way to check each coil? Or should I be checing something else?

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

I have been puzzled to why my truck isn't running right. We were driving down the highway one day and*then all of the sudden it starts running really rough. I changed MAF sensor, plugs and plug wires, oil change, fuel filter and air filter. Still doing the same thing. What this could be? 2003 ford sport trac..

Ford - 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.

Explorer :: 2000 Ford Misfiring / Running Rough / Sluggish Power

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.

Ford - Explorer :: 2003 - Misfire On Cylinder 8 / Running Rough At Idle And Under Load

Switched cop and plug with another cyl and plug.... same code and cycl 8 is definitely not working. Would a generic problem always affect i cylinder. I even checked wire clip on for injector... it appears ok. There is power to injector wire clip.

Ford - Explorer :: 2002 - Intermittent A/C - Running Cold Then Hot

Have been having problems with my a/c on my '02 Sport Trac (4x4 w/ 235K miles) running cold, then hot, then cold again but inconsistently. Aside from the fact that it always seems to happen when I'm really in need of some cold air, there doesn't seem to be a pattern...in traffic, idling, highway driving, city driving, but it does seem to be a bigger problem at lower speeds or in traffic. No issues with air flow or controls, just maintaining cold temps. I've already had the system recharged and in the past replaced the a/c manifold hose assembly, and a dye test was inconclusive.

Ford - Explorer :: 2002 - Front Right Side Damaged From Running Off Road

My son ran off the road in a neighborhood and hit some large rocks along side the street. It punctured the front right side and obvioulsly damaged the steering because now it drives terribly and instead of the steering wheel handles being side to side it is 90 degrees perpendicular. The service station I use said it has a bent frame and will need to be taken to a body shop. Will the cost to fix it be worth it especially due to its age?

Ford - Explorer :: 2002 - Rumbles And Shakes When Running And RPM Fall Then It Just Dies

248k miles on it, was taken from a body shop and put on side of road, I know who took it but can't prove it. He is known for messing with ppl vehicles. . Started up just fine when found, but you can hold foot completely down on gas and it's like it is losing pressure (?) , it rumbles and shakes when running and you can watch the RPMS fall while holding gas pedal down (in park) until it just dies. It has an "egg" smell and one side will get hot while the other stays cold. It was something intentionally done to my vehicle. .already checked Cadillac converter and cleaned/removed muffler. I'm not sure where to start looking now, I'm a single mother without the money to take it to a repair shop. We could drive it onto the trailer to get it to a friend house, but barely made it up it without dying...

Ford - Windstar :: 2002 - Rough Running While Moving

I have a 2002 Ford Windstar. Just replaced a TPS, went to town was coming back home, and all of a sudden it started to spit and sputter while in gear. But, in neutral she runs alright. I use mid-grade gas. I put in two cans of Seafoam in the tank. Wrecker operator smelled the exhaust and told me the it was too rich. My question is and this sounds stupid, could the previous owner. Had never replaced the fuel filter or if they did replaced it, that it was installed backwards. I drove it almost 20 miles before it died. I figured that the fuel in the gas line emptied and it refuse to go. And since it only runs good without strain on the engine...

Ford - Explorer :: 2007 V8 Started Running Horrible / Rough Idle / Drives Badly And Hesitation - Code P0171

I have 2007 explorer with the 4.6 V8....

Recently it started running horrible. Rough idle, drives badly, hesitation, etc. Check engine light is on, code P0171. I cannot find a vacuum leak, and i am pretty much at a loss. Before it started running poorly i replaced the thermostat, and flushed the coolant. I am assuming this is a coincidence.

Ford Ranger / B-Series :: 2002 - Running Rough Like Misfiring

My ranger just started running very rough. Like misfiring, but I think it may be the fuel pump. It starts and drives...but it surges then drives normal, as if fuel is being fed, then starved, then force fed etc. My father asked if I had trouble starting it and to be honest in the last 6 months it was a little harder to start on several occasions. On a few occasions it required more cranking. But that was only a few times.

I tried putting in a fuel injector cleaner and 93 octane gas but it is still running even rougher now. I changed out the fuel filter under the rail about a year ago (maybe 8000 miles ago at most). My father thinks the fuel pump is shot and he laughed because his went on his expedition and he said it is inside the fuel tank and there is no way to get at it without dropping the tank. Is that true? 2002 ranger xl 4cyl

Ford - Explorer :: 2002 - Hesitation / Jerkiness And Rough Acceleration After 1st Stop - Air Sound?

The problem starts after about 5-10 mins of start up and normal driving. First signs usually come leaving a stop light or stop sign. Hesitation, jerkiness, rough acceleration. It's usually slight, just enough to feel it. Soon it really shows up while keeping the truck at a steady speed, say 40 for example.

I finally heard what I would describe as a puffing air sound and figured vacuum leak.. finally! Nope.. it's coming from the rear underneath of the vehicle. I can't hear it in the engine, or the tail pipe.

2002 Ford Explorer xls 4.0 125k miles, I've replaced the air filter, egr valve, pcv valve, cleaned the maf and covered about every hose I can reach with carb cleaner checking for a vacuum leak. I've yet to try some of the other things due to hearing that puffing sound.

Ford Excursion :: 2002 - Running Very Rough And ABS Light Continuously Flash

I bought my 2002 Excursion 6.8L about 2yrs ago, no less than a week of having it I started to have all sorts of problems. (insert nagging wife here) the biggest of problems was the darn thing started to run very rough and the ABS light cont to flash, then the truck just died (engine stopped, EXTREMELY scary in a intersection) I replaced the VSS in the rear diff.. acted a little better for a while then..no luck. I called around to every ford dealer in town. I need more break light fluid to there isn't enough grease on my wobbler pin?

So I got the initiative to simplify what I was seeing and hearing. I found that there was an OSS sensor on the tail of the transmission...drove my very intense self up to the dealership and bought myself a new OSS sensor. I got home and replaced it, then I drove my truck under the largest shade tree I could find and replaced all the coils and spark plugs. (Insert bloody knuckles and curse words here) Job Done. I thought to myself if this doesn't fix it then I don't know what to do. (I couldn't sell it)...again the point being...the truck has never ran better, gas mileage has doubled and the true power of the v10 has been restored. I found 4 different types of spark plugs in it and 3 different types of coils...?
