Ford - Mountaineer :: 2004 - Running Rough - CEL On - Ticking?
Dec 27, 2014
Mountaineer started running rough couple of weeks ago with engine flashing. Had codes read, got codes P0306 and P0316. I changed the coil pack of cylinder 6, engine light went away but still running rough. Decided to change all plugs. Found cylinders 2 and 3 filled with oil so I changed the valve cover gasket. Put back together, still running rough and ticking. Pulled every coil pack and metered them.
Every one reads .6 ohms across terminals and 5.6k from each terminal to spring. I'm assuming this indicates a good coil pack. I also metered the one that I took out and it reads the same. I've also looked for vacuum line leaks and listened but found none. The engine is rocking pretty bad and the exhaust comes out in the pattern of the "misfiring". Went to see if Autozone could read a code without the engine light on but they read "no codes".

the F150 of my brother has the follow diseases:rough running ticking noises, low mileage per gallone, blue smoke out of exhaust after start, i have ordered the cam phaser, hope, that will be the reason. But today, my brother means, i have to do a test drive, because the truck has no power. and really, feels like missing of one or two cylinders. Very bad performance. Is it possible, that the reason are the phasers?

98 5.0 last week i was driving around for a few hours and everything was fine. Did some work in the garage for a few hours and had to run to the hardware store. Started the truck up and she ran like crap. Engine shaking like a misfire. First thought plugs and wires. Well by then it was late and Easter was the next day didn't get to it till Monday. Well after the change still crappy running.
So I changed the fuel filter and cleaned the mass air. No change. Checked for spark on the coil packs all have spark. Checked the PCV all good there. Checked for vac leaks none found. During that I noticed a small hole in the EGR tube I repaired that but still running like crap backfiring out the exhaust, engine shaking badly at times. I also changed out the FPR on the fuel rail. No change of course.
As of today I changed the coil packs. Again no change. Only code it throws is a EGR high flow after I fixed the hole but was having problems before that.

The wife's 08 Mountaineer has an exhaust tick when it's cold. Goes away after it warms up. EGR valve sticking or something? Is there an easy fix?

My 2006 Mountaineer 4.6 is ticking at start up, and it gets quieter after about 30 seconds. Does this sounds like the cam phaser?

I have used a wooded stick to locate a ticking or knocking noise on my fuel rail. I can't hear anywhere else on the motor. I took it to a mechanic and he told me it was the timing chains and guides. Sometimes it is very loud and other times it barely noticeable. 191k miles so I am not going to spend $ rebuilding the front of the motor. Just want to be sure it is what he says before I scrap it out.

My parents have a 2007 Mercury Mountaineer, 100,845 miles. They change oil like a religion. It has under the hood ticking that increases and decreases with RPM. The ticking (tickity-tickity) sounds like when there is low oil. People have said,"You better put oil in there..."The oil is full. I can't tell if the sound is coming from inside the engine, or if something on the engine might be loose that is causing the ticking as the engine RPM changes. From what I can remember from auto shop in the 80's...it kind of sounds like valves/lifters.
Also, it has a strange road noise that I think is coming from the tires. It sounds and sort of feels like riding on knobby off road tires. I can put it in neutral and turn off the engine, and the noise remains and decreases as the speed does, so it is not from the engine.

A couple of days ago (Friday, Sept 14th), I noticed my 98 V8 5.0 liter Mountaineer was idling rough. I had the codes pulled and got P1401, P0455 and P0308. I did find a vacuum leak and fixed it (changed the air filter and cleaned the MAF while I was in there). I also replaced all the plugs (based on the P0308 misfire). I cleared the codes after that with a neg battery pull.
I'm still running slightly rough at idle, but not as bad. However, I have found that when I get up to about 45MPH (1500 RPMs) I started to get a worrisome shaking/ vibration. It's difficult to tell where it is coming from. If I let off the gas, or give it more and go up to about 50 mph, the shaking stops. It is only when I'm pressing the pedal in this range (like it is having trouble switching gears, perhaps?). Over the past two days of driving it and testing, I have been to autozone and had the codes checked. Nothing comes up, and no CEL.
I just had a new trans put on about 6 months ago. The only thing that preceded this issue was I got an oil change the day before this started at a place I don't normally go to (unlikely, but since they didn't write the type of oil they used on my window tag, I figured I'd mention it). I've read some suggest it to be a tire issue; but that strokes me as odd, since the shaking only happens when applying gas.

History: Truck was running okay but acted like a coil was bad when under load. I changed out all the plugs with Motorcraft and put on Summit racing COPs.
After the plug and cop change the truck will run rough after it is warmed up. I changed back to the old COPs and it runs the same.
First I replaced the MAF sensor after finding many posts on here about it. No change.
I read a bunch of posts on oil causing the problem so I used 10-30w and nothing changed.
I searched for a vacuum leak with carb cleaner and couldn't find one. I removed, cleaned and reinstalled the throttle body.
When I did the plug change I disconnected the PCM without disconnecting the battery. Would this cause this type of problem?
I think this is about all the stuff I found to try in the threads that came up through searching.

My f-150 has an intermittent rough idle and consistently runs rough when you accelerate quickly. Vehicle is not throwing any codes?

I have a Ford F150 XLT. I have 67000 miles on it and the other night it just started running rough out of no where near idle. Once you got over 20mph the rough running would go away. I took it to get an engine change and engine flushed but it came back. It doesnt always run rough near idle or below 20mph. The Ford dealer says my engine has only 22 psi oil pressure near hot idle and cant engage the VCT phazers and they want to replace the whole engine.

My 05 was running rough and misfiring quite frequently. After much deliberation, I took it in for a diagnostic hookup. The dealer said my driver side cat was clogged. Lucky for me, I was just under the warranty period(79673 miles). I have had it replaced and I can feel a noticeable difference in the way it runs. Could a clogged cat have made it run that poorly or am is it just in my head that it is running alot better?

I just completed a successful second spark plug change, using Motorcraft SP515 plugs just like last time. After reconnecting battery and starting engine, it ran poorly throughout a short road test. Felt like it was skipping. Checked under the hood and found that the #2 fuel injector was disconnected, so I reconnected the injector.
I took another short road trip and it still ran poorly as if skipping. So, this time I disconnected the battery for several minutes while removing the #2 plug thinking I may possibly have fouled the plug by the injector not being connected. I also checked all of the other injector and coil connections. Reconnected battery and took another short trip. It still runs poorly. No codes yet.

So I bought an 04 3 months ago everything seemed good all deltas were good had a small leak nothing serious. I had the egr deleted then i did the mistake of flooring it 1 morning at top end and the mech is telling me threw a valve. The truck was stumbling and running ruff with white smoke. looks like cycl. 7 took a hit and shows 10 psi of compression. The injector are in working order and so are the rockers. the bill is 3500 all in for new gaskets and oil cooler head work, arp studs and labor.

I have 07 sscrew with 5.4. 93,000 miles. At start up truck runs perfect. After 20-30 minutes of running motor will start to start running rough at low rpm. Diesel sound. I can rev up and motor clears up and idles fine. Should I replace VCT solenoids? Or phasers? Or both at one time??

I just bought a 2007 F150 XLT with a Triton 5.4 with 80,000 miles on it. My problem is this, the engine seems to run ok ( a bit rough) until it gets up to running temp and I have driven about 10- 20 miles then most of the time, it starts to act up.
When I am driving it is fine, but when I slow down and come to an idle about 500rpms, it sometimes runs very rough, sounds like a diesel and shakes violently. It feels like it is doing damage. Sometimes it stalls. If I rev it back up immediately it will smooth out.
In speaking to some friends they've suggested things from plugged oil channels, (affecting the cam phasers? All the way to it needing new chains, phasers and guides. I don't want to spend a ton of money doing an improper service repair only to have the issue show up later . But there seems to be a lot of different answers to the same problem. Is the dealer going to be able to diagnose something like this fairly well? Or should I try to narrow it down a bit first?

I changed the timing chain, phasers, tensioners, guides, and cam sensors and solenoids about 30k miles ago. Truck now has 170k miles. This past weekend engine started running so rough, it had the whole front end shaking. Threw 8 codes..1 bank..lean, bank 2 rich, timing retarded, cylinder G and F misfire, and more codes. It seems to have jumped timing pretty bad.

I just had my 04 5.4l engine rebuilt. Ive driven it about 500 mi and it started running rough at a stoplight. I tapped the accelerator and it started running good again but service engine light came on. I pulled the codes and they were P0022, PO345, P0340,and P0430. It has done this several times now. Everything was replaced including the phasers, except for the camshaft sensors. Could they cause this problem?

On my way into work this morning, my 06 with the 5.4 started running very rough/shaking at low rpms. I could kick it out of overdrive and it would smooth out and seemingly be fine at higher rpms.
This worked out for a couple of miles until the truck just died on me completely. The Edge is showing po351, 352, 353......358 codes. Ignition coil Primary/Secondary circuit fault on every cylinder.
I'm thinking its unlikely that every coil failed simultaneously....computer? When I try to start the truck, it will try to hit on a cylinder or two, but will not run.

When I first start my excursion in the morning, it starts fine, idles fine. If I don't let it sit for about 5mins plus i have this issue. I will start off and it has no power at all. I can barely get up to 20mph. It doesn't seem to want to change gears, I don't hear the turbo spool up. Then all of a sudden it will go to next gear, turbo spools up and it has power again. It is like I said a 6.0 power stroke, its a 2004 excursion with 214k miles.
