misfire

Hi I have a 2000 v8 ford explorer that started misfireing when it is first started. When trying to accelerate there is now a lot of shaking and loss of power. I bought the explorer a few weeks back. It had misfires in four of cylinders then. After I changed all the sparkplugs and fixed two of...

My explorer has had really bad gas mileage lately and has rough starts on and off along with rumbling at idle. I have had it in a shop for the last couple days having diagnostics run on it and they told me they think, but don't know for sure, that it is a bad cylinder. Cylinders 1 and 5 have low...

Okay. Here's the situation: I have been having off and on misfires for almost the past 6 months now. what started out as rarely happening is now becoming a trend. I first blamed it on my bad trans, but that has since been replaced by a new rebuilt one. This happens usually when the Ex is...

OK, so I have a 2005 Lincoln Aviator, comes standard with a 4.6 (just like the Marauder). I have replaced the crankshaft position sensor, camshaft position sensor, spark plug, fuel filter, ran Lucas fuel injector cleaner, and replaced OEM coil packs with Accel coil packs and I still get a...

Okay, a little background on my driving... I am an aggressive driver with a heavy foot, always complete maintenance on time and fix issues when they come up. If I could I'd go back to a sports car, but with a family in tow... I'm happy driving my V8 Explorer. My Vehicle: 2003 Ford Explorer...

well as the title reads i believe that i have blown my engine but im not entirely sure. about 2 weeks ago i heard a pop in the engine bay while driving followed by a terrible knocking/banging noise and the heavy scent of gas. after getting it off the road i checked the codes and it had said that...

hey everyone, kind of stuck in a jam here. was driving around today when out of nowhere the engine in my 04 4.0 started a violent knock. it threw a misfire code for the 3rd cylinder and i swapped the plug. now it is still knocking and there is a distinct smell of gas. can someone please...

Hello all. Hopefully someone can help me out with this one... So on top of numerous other issues I have encountered with my Explorer, this one really boggles me. I live in Flagstaff, AZ elevation:7,000 ft. Last summer I traveled two hours south to Phoenix which is about elevation 2,000 ft and...

Hello, I recently had the fuel injector service done on my 98 Explorer while at Wal Mart. Initially, it ran fine, but within a couple of days I started noticing a hesitation when I would accelerate as well as a very rough idle. So I had the CEL code read and was told that Cylinder 4 was...

I have a misfire and rought idle that is very repeatable after about five to ten minutes of warmup. No DTC codes are set. I bought the ScanXL software from Palmer Performance Engineering (PPE). I was surprised to discover the data collection (USB) device that I bought from Amazon was...

Still trying to get my 1992 Ford Explorer 4.0L 4dr Auto 4WD VIN X to run properly. Here's the current situation: It starts fine, runs about 30 seconds, then chugs, loses power, and Check Engine Light comes on. What we've discovered: It is running on only 2 cylinders now. When I pull...

background: explorer ran fine for a year or so after I bought it, however would notice sometimes at WOT the CEL would flash briefly till I let off the gas, and it would accelerate and run fine fast forward to a week ago, I finally got a CEL that was constant...ran the code and got...

Greetings! I just bought a 2007 Sport Trac Build date 04/06 So Gen1 I guess, 102,000 miles and no idea really how the owner before treated it. After the sale I had the infamous misfire under load, original spark plugs, so I decided after reading all the horror stories on here, that it was worth...

Greetings all, Recently bought an 07 Sport Trac 3V V8 with the 6 speed 6R60 with 100,000. She's beautiful and I love her, but I'm having a repeatable misfire that threads on the internet have led me to believe is a spark plug/coil pack issue. I have a friend who has offered to help me with...

I have a 1994 Ford explorer in France which has recently picked up a small misfire. I have had the plugs changed and it made no difference at all so I guess it is the spark plug leads next and then a new coil. The thing is the local garage apparently has no way of sourcing these parts so I am...

02 Ranger misfires on #2 and #4 cylinders. 3.0 V6. Where should I start?

ok gang, My "Service Engine Soon" Light came on today. I took it over to advanced auto and the there was one one code being thrown... Misfire in cylinder 6. My 1st thought was the plug or the coil has gone bad. I pulled the coil (1 screw) and the plug to see if there was anything obvious...

Hi, I have a misfire on my 02 limited explorer. It runs ok when cold, but once it warms up, it has a rough idle, and misfires under light load in lower rpms. At WOT, the engine surges and the HP curve is not smooth at all. I've ran fuel injector cleaner twice, changed the plugs, and changed...

Please someone help! It only does this at Idle. My mechanic has checked/changed fuel trim, plugs, coil pack, wires, timing chain, fuel pressure, fuel filter, etc..the basic stuff you would think of. I took it to the dealer today and had the PCM flashed with the latest software as he thought that...

Just to give you all some background info I'll tell the story that lead to this dead cylinder in my explorer. It's a 97 XLT with the 302 v8 and all wheel drive. My radiator started leaking coolant early last month, suspiciously a couple days after getting some recall work done by the ford...

I have been battling a slight misfire for a while. It generally consisted of a jerking motion whenever you try to accelerate hard and the actual misfire starts at almost exactly 2000 rpm. This misfire only happens under acceleration, so if you are just cruising, it is really smooth. The misfire...

i had replaced the intake gaskets upper and lower a little over a month ago to fix a rough idle. it worked for a while but now i am getting a misfire my cel is blinking and my car has a major loss in power and the dash flickers on and off radio restarts. i am receiving two codes at first i was...

I am having multiple issues with my 1997 Ford Explorer. Engine = 4.0 SOHC, Vin E. I am by no means a mechanic, but I can do my own work. When I first start the engine, the RPMs highly fluctuate, a heavy vibration, and the engine rev's on its own. I have been experiencing very low MPG and...

Ok, well after quite a bit of work my explorer is driving great and I can get around 20mpg if I'm nice to it. It starts right up every time and under normal driving it shifts ultra smooth. Well, when I got it it ran like crap and afer I did all of the basic tuneup steps, I decided to run...
