Video not required.Is there a video out there somewhere?? I've been looking to no avail
great Thanks helbigtw for the heads up, I'll leave them alone then, much appreciated.I wouldn't replace coils.
Maybe 10 years 150k miles.
I changed my plugs about 15k ago last year.
I have yet to have a misfire detection
or any issues. Mine is an 08, 93k. Coils should last awhile.
Might want to check these out too.is it a good idea to change the ignition coils at the same time when swapping out the old spark plugs ? or it's not necessary ? thanks in advance
Looks like Qty. 3. See posts below from Davicho and 4wdmotionHow many of the gasket do I need to buy. Is it 3?
I did this a while ago too and I am sure it was the first time the plugs had been changed. The engine had started to lunge a bit at highway speeds, that's how bad the gaps were. Once replaced, the engine returned to its normal glory days. Nice write up.Thought I would add my experience here. Just did them on my 2008.
Thanks for the info thus far. It's helped me move through the job.
Here are my tips:
1. The Motorcraft plugs DO NOT COME PRE-GAPPED. You must gap them to .051" - .057". I used .055". DO NOT use the electrode tip to pry against.
2. My car had 80K on it and definitely needed the plugs changed. The gaps had eroded to about .070"
3. I have read that some say you can reuse the green gaskets. Mine looked good but compared to the new ones, they were not very flexible and felt "dry" and hard. These should be replaced.
4. This job is a bit of a PITA, buit with some clever hose removal, it's not so bad. BLOW the engine and crevices out with compressed air prior to diving in. Removing the plenum is fussy and hangs up on numerous things. This can knock debris into the intake runners.
5. The two back hoses are the toughest. For the passenger side one, I waited until I had the plenum lifted off a bit and could get to it. I pulled it off from the valve cover end. Slight twist and off it comes. Right next to it is an electrical connector that is almost hidden. You can remove it "blind" if you try.
6. For the hose with the "fishnet" behind the throttle body, I traced it to behind the battery. I removed the battery and then removed the bracket shown (in red circles). Pretty easy. I could then get at the hose end there and fished it around and removed it with the plenum.
7. I needed to remove the valve directly above the throttle body for clearance (green circle).
8. The plenum is a tight fit but comes out straight towards you with a little fussing.
9. Be VERY careful not to drop anything into the intake runners. I placed a towel over them once I could.
10. I agree with the warning not to use power tools on the plugs themselves. This seems like an engine that is not very tolerant of brutality.
11. The coils were a bit stuck. I pried carefully from under and to the right of the screw mount hole to ensure I was prying against the full thickness of the bracket and they popped up with a little effort.
I can only imagine a careless mechanic doing this job. Small washer down the plenum or dirt/debris. It's also easy to lean on the air conditioning hose on the passenger side. Too much leaning and this thing is going to leak really soon. Easy to "break" the thin wires of the numerous electrical connectors. Each one of these will not manifest itself right away, but will almost certainly result in frustration and difficult troubleshooting to come- all without the culprit to blame and your time and money as the casualty. I strongly recommend participating in watching your mechanic do this job. If they mind, find a different mechanic. In all, took me about 2.5 hours, working steadily. 2 hours I suppose the second time around.
