My ls has been missing for about 4 months now. And when a code pops up i always have it checked and fixed. Usually its a coil. And now it wont throw any codes. Going up hill it misses. And during idle. Ive replaced plugs, fuel filter and the air filter and have done seafoam treatments. I dont know what else. and this morning when I was going to stop at a stop sign it is almost kept going through stop sign. It then popped up with a etc failsafe mode. I then had my car scanned and these codes were stored in it:

P0316
P061b
P2106

Now my car had a leaky coil cover, so i was told im going to need a whole new valve cover because the screws couldnt be torque down all the way. But for now ive tryed to seal it with silicone. Could that be The problem? Moisture?
Anyways yall have any ideas?

Its a 2005 ls v8
 
Replace all COP's, Valve cover gaskets and spark plugs. This should cure your problems. I have never heard of a valve cover not being able to be torqued down tight enuf. Not to say it cant happen but the only reason for that would be the bolt holes are stripped. A new valve cover would not help that issue.

It's his coil cover that won't tighten down. Replacing the valve cover would fix that. However, that's not really where the problem is. He needs to replace the wiper cowl seals. That's what has failed and is pouring water onto the engine. If he doesn't fix that, he'll still have problems even after changing out the valve covers and getting the coil covers on tight.

I bet he meant the coil cover and not the valve cover. It sounds like he needs the seals for the wiper cowl too (that's where the water is coming from).

You are probly right Joe. I think somewhere I read they made an upgraded gasket kit for the coil covers IIRC, I could be wrong
 
Yea my coil cover is broke. The things the bolts screw into are pulled out. But im looking for a little band aid i guess. I dont have 300 to spend on coils and plugs then 500 for a valve cover. And sorry newb question but whats a wiper cowl?
 
So your Valve cover is broke, not your coil cover? Valve cover covers the valve train and cams, a coil cover is the smaller piece that just cover the coils

If the other answers weren't clear, it's also the part that you take loose on the passenger side to change the AC filter. There are two big soft foam seals that will be coming apart. You can replace them with door weather striping that you buy at Lowes or elsewhere.

You can epoxy the inserts back into the valve covers, but it's not worth the trouble. Personally, I'd just calk the coil covers back on.

The important thing is that once you fix the foam seals, you will have to replace all the coils and all the plugs one more time, and do them all at the same time. Otherwise, bad parts will kill good parts and you'll never get this fixed. If you let it go too long, you'll kill your catalytic converters and maybe even your PCM.

That happened to me also. Clean out the "holes" and use JB Weld to install the supposed-to-be captured nuts. Let it dry overnight (I waited 24 hours or so) and reinstall the bolts. I also expanded the "nuts" a little to make sure they were secure in the hole.

Much, much cheaper than a new valve/cam cover. I had 3 bad bolts.
 
When I went to do my Coils & Plugs, we found on the drivers side coil cover, far lower corner, that someone had been in there before and forced the last bolt out by cracking the corner of the coil cover itself. (very tight spot to get bolt out)

The cracked corner was far along enough that the bolt would not grab much in terms of tightening down that corner.

We flipped the bad coil cover from drivers side to the passenger side so I can get it out easier next time.

I hope to pick up a used one at a scrapper one of these days to replace it with.

In that mean time it was bolted down and some hi temp silicone was used where the
corner was broken and on both sides where the COP wires enter the housing.

This should keep my new coils & plugs from getting any moisture in it.

Also keeping an eye on my wiper cowl for the time being and try not to drive too much in the rain.

Coils, coils, coils ... :Bang

Happened here as well. The monkeys at the dealer I used to visit overtightened one coil cover bolt, and the whole thing came out.
 
Pm me i may know where to get u new covers cheep
off a 2000.
I had same pro at the cal there talking about.
Only missed when it rained hard.
And yes the guy that told u about yor cats going bad,it dont take much if its missing bad.
 
Okay. New problem. Recently I've been experiencing a "ETC failsafe". I first noticed it when I pulled up to a stop light and it lunged forward, and when I slammed the brake down farther it stopped and popped up with the failsafe message and missed a little bit before returning to normal. It only did that twice during that 12-15 mile drive. sometimes it will do it most of the time it wont. The codes are :
P2106
P061B

Both of the codes repeat about 3 times each. Could it be a TPS or accelerator sensor? or just something simple as coils and plugs? Or (knock on wood) could it be a throttle body. Any input would help. Thanks!
 
It could be any of those things, but it is probably coils and plugs. What brand of coils did you use last time? Did you replace all of them? Did you replace all of the plugs? Did you verify/set the gaps to 1.0mm, no more, no less.
 
Autozone brand coils. were cheaper at the time and lifetime warranties. I replaced all and all plugs with double platinum I think duralast. they were already pre gapped. they are about 35k miles old. But coils doing that just sometimes?

Every set of plugs that I have bought have been pre-gapped, and at least a few of each set had the wrong gap.

Were the coils enough cheaper than the Motorcraft coils to pay for a set of catalytic converters when the time comes?

This is the normal failure mode of the coils on the LS. They become marginal, they don't fail outright. Marginal in this case means they don't fire every time or when they do the voltage is too low.

so thats a no... that alone could have ruined a coil or two... now you get to guess at which one is failing(which the car has trouble doing half the time...) or buy a whole new set.



always at least check the plug gaps!!!
