I got home from traveling and my ranger was sitting at the airport for 5 days.

I got in it yesterday and when I was driving home everything seemed fine until I tried to pass someone and I notice a serious bucking/wheel hop action when I am pushing the accelerator pedal hard. I let off and it drives normal. This also happens going up a hill and it starts the bucking action.

As long as I don't push it hard it drives normal but if i try to push it faster it acts up.

I checked my slave cylinder for any leakage but nothing was wet and and everything looked good related to the clutch so I'm thinking it's engine related.

Anyone have any ideas where to start? I don't have a check engine light and this just started after it sat for a while.

Before I left work I cleaned the MAF sensor just to be sure it's cleaned and driving to work it didn't do anything abnormal.

I will continue driving it as it is, but anything simple I can check to make sure everything is working fine?

Of course since this is a consistance deal this is going to be fun to diagnose.

Sounds like something in the ignition system. Sufficient spark to tool along, but breaking up when you squeeze the trigger.

What I was thinking, I drove it around after work and didn't have any issue. But this weekend I got nothing going on and I'll probably inspect everything and see if anything pops out as a issue.

It's been roughly 50,000 miles since i last changed plugs and wires so maybe it's time to do it again.

Hopefully the coil pack is fine that's a expensive unit! LOL

Check the IAC. They don't cost that much and are pretty easy to replace. Some folks will say "clean it" but I find that a kind of futile exercise for the little extra life you get out of a part that can be had from Autozone for $50 bucks (around here at least) http://www.autozone.com/autozone/parts/2003-Ford-Ranger-2WD/Idle-Air-Control-Valve/Duralast/_/N-jkcelZ9gsofZ1z141xg

When my 4.0 was doing that, changing the plugs and wires fixed it. I had over 70,000 miles on them and it did the same thing, it would buck so bad you thought it was going to quit running. I've got 50,000 miles on that set and it's start to miss once in a while again.

But mine was in the same situation, running it hard. Anything less than full throttle and it ran fine.

I thought the IAC only works when the motor is idling?

I'm not 100% sure but that's what I thought I read somewhere.

On a side note, I haven't notice any issues since I cleaned the MAF so that might have been the issue but I know the plugs are due for a change.

Also my O2 sensor might need to be replaced, 117,000 miles on the factory original units!

You guys are going to disown me when I tell you this...

I bought my '05 (4.0) with about 16k on it, and I currently have 126k on it. I've never replaced the plugs or wires. Still runs like a top. I'm almost afraid to change them now.

Yes that's true, unless it's clogged with carbon build up. Take it off, douche it really well with brake cleaner and see if there is a difference in how the truck runs.

Well, I pulled the plugs and found that the electrodes was wore down. I had a gap of .055-.06 on all 6 of them so I bought new ones and gap them at .044 as per factory and took it for a ride. It's not doing it now but then again it wasn't doing it after I cleaned the MAF sensor too. I'm going to do some more maintenance on it as I get time but right now it's running good and not having any issue.

List of things,

Fuel Filter
Spark plug wires
IAC
EGR? ( Never had a issue and never took it off as it's the original unit.)
Cam sensor shaft( I've read these thing wear out on the 3.0L and I might want to check it)


Anything else to check without having to replace anything right away? It's sitting at 118,000 miles on the motor.

Cody,

Did you figure out the issue? I've got 122K on mine and it's doing the same thing at various speeds. I've replaced the plugs, cleaned the MAF, just had the clutch replaced. And between 70-80 its does the same thing.

Haven't noticed it after I replaced the plugs.

Every once in awhile i think it's doing it but I can't tell if it's the road or the engine doing it.

Guess I'll run it til it breaks.....

Afternoon folks!

Been dealing with this miss in the ranger for the past 2 years and today I think I made some progress.

It was missing last night really bad it sat the past 2 days and it's been wet and snowing here. It was missing so bad to the point that I seen my cat glowing red in the dark! So this morning I cranked it up and pulled the plug wire for number 3 cause that was the one that was reading no firing as per the codes I pulled. It didn't make a difference so I pulled the wire off the coil pack and stuck my finger over it and didn't feel anything. Then I stuck a screw driver in there and it shocked me hard! Then I just stuck my finger over it again like I did earlier and this time it shocked me!

So I put the plug wire back on and it was not missing this time. So it seems something is fubared in the coil pack as it was still missing going down the road but not as bad as before. So I got a new coil pack and for shit and giggles I threw a new set of plugs and wires. Seems like i got some more power compare to what I had in the past few months.

Hopefully that's all fixed but only time will tell.

Oh and yes I'm still alive and yep I still got this truck!

That's the first clue I had that my plug wires were going out. The originals lasted around 70,000 miles and they were still firing but I replaced them anyway. Then after about 30,000 miles on my new "premium" wires, it started missing a little on wet days. Not so much under power, but on very light throttle, like maintaining speed when coasting down a hill. It would kind of stumble a little. Replaced them and the problem went away.

Mine was bucking and missing under load and cruising. It was really bad but I noticed it was only on wet days.

Closer inspection of the old coil I see hair line cracks in the epoxy on the bottom and some discoloration amoung the area that number 3 was located.

So far I haven't had the issue and I feel like i had more power going up hill today! We will see after some more time has gone by.

Oh and the plugs and wires was only 20,000 miles old.

The plugs looked good except plug 3 was brown compare to the white plugs
