Alternatively, you could buy the drive/driven gears. I think you can get the set for under $100, but it's been a long time since I looked.

I should quit posting...

Another thing that was mentioned in another thread, something I often forget about. Perhaps your cat is plugged.

Can't reschedule a golf tournament for my late deceased boss.

And the fuel pressure when it starts sputtering out is still within spec?

Copying for future reference. Much appreciated.

Additional engine cycles will be needed for computer to run all of the diagnostics.

The codes won't "clear" themselves automatically. They will just stop causing the CEL to turn on after the conditions that caused them is corrected. They will remain in the computer. As far as I know, there is no ...

I understand. It's easy to say what needs to be done, but completely different to go and do it. I hate to think that it's the fuel pump. However, I can't see a lot of other solutions. Are your BCS/BCA working? Are you dumping boost at 3k rpm?

My 220k+ 4.6L would argue that there is no knock knock. If it weren't for the fact that my rear shock towers rusted out, that engine would still be seeing 5.9k and daily use.

Don't be hatin' on the 4.6.

I don't recall what the factory gap calls for, but I always run my plugs a .060" on my coil pack equipped vehicles. However, the temp of the plug will not have a bearing on the gap you use. The actual difference comes in with how much heat the plug aids in removing from the cylinder. So whatever you ...

You guys would pick a day when I have premade plans, wouldn't you?

An amigo of mine suggests running the Ram Air manifolds for your 455. I have no reason to doubt his advice as he's done quite a bit of research on these things.

He has also advised that if you really want headers, that GP headers *should* work, but they won't be a perfect fit. Additionally, they ...

Then you have an issue with either your pump check ball, or possibly a clogged/stuck injector. Supposedly you can stick a 194 bulb into the injector plug to verify that it is receiving a signal to open. If the light stays on constantly, you have a bad injector driver. Since you've already replaced ...

A general rule of thumb is that your pressure should not bleed off 2psi or more every 3 to 5 seconds. You should be able to hold close to operating pressure for 10 minutes or more with the engine off. So when you say it drops to 10 after the pump shuts off, is that drop happening quickly or not?

I can't speak for the 95 an earlier ssei, but I would assume it is. So, if you prime the fuel system, it bleeds off immediately after key off?

Also, could you give us a summary of your fuel pressure testing procedure? Perhaps your fuel pump is not able to keep up with the fuel demands?

If you have ...

Breaking tabs in the fender?

For what it's worth, you'll only break them once.

Well. I'm most certainly not a pro like most of the other guys that frequent this section, but I'll impart what I know.

If you have the funding, go bigger on the amp. You can always turn it down.

My first subs were a pair of 10" kicker comp vr's and a sony xm 1002 hx.

I then got a pair of planet ...

spraying it is not always sufficient. A q-tip and some isopropyl alchy or other qualified electronic cleaner will be sufficient. Just be very gentle when working on the MAF elements. They can be unnaturally delicate.

Or, ya know... unplug it and see if that helps for a run or two.

Obligatory.
