misfire

Hi all, I've searched google a bit but I'm not even sure what to search on. I had a miss-firing 4th cylinder & I repaired it by simply changing out the sparkplug. I haven't really driven it yet but it, obviously, significantly better just from the smoother idling. (Perhaps it isn't...

I was wondering if anyone knew when the ignition coils should be replaced .... The truck chuggs when you push down on the accelerator and when I took it to the shop they hooked it up to the scanner and it said it was in need of a tune up and it was misfiring, that the O2 sensors are bad and...

So I have an engine misfire/backfire problem. I've been dealing with the code P0305 for about 2 weeks now. Last week I got the spark plugs and wires changed, and this week I did both coil packs. Now get this. Obviously I know its Cylinder #5 with the issue. I ran the car and drove it...

So recently, I had a #7 Cylinder Misfire in my 1996 AWD V8 Explorer. I got the plugs, wires, and coil packs changed with brand new ones, and now I have a misfire on Cylinder #5. Anyone know what could have happened? I get the code P0305 and sometimes the check engine light flashes. Before the...

:mad: I have had the same problem for MONTHS. I have codes p0301 p0302 and p0303 and no other codes. What would cause these codes and no other codes? I'm stuck and have no clue where to begin. I don't have the money to take it to a mechanic. Any help will be MUCH appreciated. Thanks

I've been trying to diagnose this problem for a little bit now and I want to see if anyone has an opinion out there. I'm pretty new to car repair. I'm going to get in there this weekend I just want to have it kind of nailed down before I get there. I know I have a misfire on cylinders 5 and 6...

My 1998 Ford Explorer 4.0L OHV recently started misfiring erratically. I took it to the shop and had them take a look but since I'm rather low on funds I had them do my brakes and I decided to do the plugs, wires, and ignition coil myself. This is the first car I've ever worked on. I replaced...

:mad: I am having TONS of trouble with my 2002 Ford Explorer Sport 4.0 and need help. I have already checked the codes and get: P0301 P0302 P0303 and P0174. I have also had the ignition coil tested and its fine. The CEL flashes when the engine has warmed up. Mostly after sitting at a light for...

Hello all! Hoping someone who is very automotive savvy can help me out here with an intermittent problem my Explorer is having. Please bear with me this is a little long but I want to make sure I'm providing all the needed info. 95' Explorer 2WD 4.0L V6 Pushrod EECIV (No CEL) 237,000miles...

:exp:Hi all! Have been chasing a P0308 (cylinder 8 misfire) code now on my 02 Limited for about four weeks. Here is the background and what I found after 4 weekends of beating my head against the wall. 1. changed the plugs 2. oil and filter 3. fuel filter 4. lucas in the tank 5...

Ok, so I'm stumped on this one. I would consider myself fairly good at diagnostics, but this one has me ( and apparantely a number of Ford master techs, and others, stumped) Not mine (yet???- The owner is fed up, and I might be able to buy it cheap as is, but I;m a little scared of this...

Hi, I'm new to this site and this vehicle as well. I purchased it with 106,000 mi., and a number of problems. I am hoping that someone can shed some light. Besides the low speed firing of the ABS system that is bugging me, I am pulling numerous codes on bank two for random misfire, cyl 4,5,6...

My Explorer started running rough w/CEL on. Code received P0308. I replaced fuel filter, air filter, spark plugs, wires, coil pack. When removing Cyl 8 plug, there was moisture on internal end of plug. Plugs looked fine, but replaced any way. Vehicle idles fine when in park. Runs fine...

If anyone can help with this it would be greatly appreciated. I have a 1998 Explorer with the 4.0 SOHC and about 98K miles. Everything was fine when I left it for about two weeks in the driveway. When I came back the MIL was on, running rough and a moderate to loud ticking noise. It was a great...

I've got a misfire on one cyl - no fuel - on the farthest right bank cyl, if you are looking over the engine on the front end. I dont know how the cylinders are numbered. It could be no. 5 or 3??? I replaced all spark plugs and HT cables. I disconnected and reconnected the injector connector to...
