Time for valve stem seals... 2005, 4.4i, 113,000 miles

Excitedly waiting the confirmation of success but it's been great to be tuned into this channel.

Well... it runs... but it doesnít run well. I had this same result the last time I changed coils, I am going to put the original coils back tomorrow night and I would guess it will run, guess weíll see!

Update to follow!

Havenít pulled them yet, Iím sure it was misfires did the same thing last time I installed these coils... starting to think suspect coils.

Will pull codes tomorrow when I get home and go from there.

A stored coil code will get you into limp mode. You need to clear codes if so before engine won't run like crap.

I always clear any codes before initial start after any engine rework

Shouldnít have been any codes pre-ignition, I checked and cleared everything just before I pulled the battery to start the job.

What I didnít do was recheck after reconnecting and charging the battery before I started it the first time.

That said, I primed it a few times, key on 30 seconds or so to cycle the fuel pump a few times and then it fired right up - ran pretty smooth except for that annoying miss that I think is a poorly seated coil... I bought these new, tried to use them a while back and also had issues with a miss, weird though, wouldnít follow any specific coil, cylinder or plug so I pulled them and put the old coils back - ran like a charm! Iíll pull codes and reset tonight but Iím guessing one or more of those coils may have an issue or just not be sitting on the plug right, Iíll probably end up pulling them to get it running and then doing single coil swap until I either get all of the new ones on or find a bad/suspect coil...

Fingers crossed I would like to get back to it tonight.

In spite of probably being over ďcautiousĒ with everything during reassembly... I am getting continuous misfires on 6, 8 & 3.

Sadly I have swapped coils, plugs, plugs and coils and am still getting routine misfires on those particular cylinders.

No tapping or ticking in the head, everything seems, sounds quiet, or at least like it was before.

Valve covers coming back off??

Make sure plugs are gapped. You said you switched I'm guessing you just swapped with a cylinder that didn't have error. You could be working through some bad gas also.

Check your fuel rail pressure make sure you're holding 50 psi under load
