Misfire / knock... Halp!

[Slacker1357]

I was going to drive my car to the armory this morning.. but my car had other plans.
It started a little rough... but I kinda ignored it.

I tried backing out the driveway and pulled forward... and it sounded like hell.
Its knocking real bad, misfiring...
I guessed plugs and wires... (even though I put NGK's in a while back)
well, after a new set... I think it sounded worse!
WTF is going on????

where do I begin? I hope this isnt an engine job. My car will sit a long long time before I decide to do anything with it... I will be deployed soon.

:sulk2:

someone please also help me verify what the spark plug order is... hopefully its not a stupid screw up like that with the new plugs.

coils are marked on the mounting bracket, but from top to bottom they go 1-4-2-5-3-6

Open up your ecu and see if the caps are leaking.

[Slacker1357]

this sounds like a real hard knock. Im thinking its something a little serious.
Reminds me of when my old '88 jimmy took a dump.

[GTOJOE]

I agree with Hans. Check your ECU for leaking caps.

How's the oil pressure look?

[Slacker1357]

IIRC the oil pressure was fine. But I have been burning oil just like most 3S's

I will inspect the ECU shortly and come back here with results.
Thanks for the link... helps me understand more of what Im doing.

3000GT pictures by slacker1357 - Photobucket (http://s157.photobucket.com/albums/t67/slacker1357/3000GT/)

The pics are a little bigger on my memory card... Photobucket is crap

[Slacker1357]

I took a 2nd look at the "caps". Saw tiny bubbles in the one, and larger ones in the other two.
I dont think its healthy. Who can I have fix it?

also... how possible is it that it may be the coil packs? and how could I test them instead of burning $150?

[Alex3000gt]

Looks like the capacitor next to "IC105" & "C104" has leaked and left residue on the circuit board.

[Slacker1357]

yeah... It did look a little strange... but wasnt sure.
Anyone here I could mail this too and have fix?

Im tight on cash, but I would rather get this fixed while its still nice outside and Im still home

If your proficient with a soldering iron it will only take 5 mins. If your not then don't touch it and bring it to any local electronics shop.

[Slacker1357]

yeah... I havent used a soldering iron in at least 5 years. I wasnt that great at it then either.
I will have to find an electronics shop then.
any big name ones you think might be near me?

Im gonna ask a few buddies near me if they know anywhere...
just seeing if you guys have any intel

[GTOJOE]
