Thanks man, really appreciate the info! Exactly what I was looking for.

Hi guys, about to change the wires and plugs on the 03 SS. Just curious as to what size gap I should be going with. I'm going to go with MSD wires and NGK TR5 V-Power plugs. I have read anywhere from .30 - .60 as for a gap. Which one should I go with and why? What will a smaller gap help where a wider gap fails and vice versa. Thanks in advance guys and sorry if there has been a topic about this already. I searched and searched, but could only find topics of the which plugs and wires to choose, but not really talking about gapping. Again, thanks in advance!

Thanks for all the help guys! Means a lot to be able to get help when needed. It may be a little while before I preform this minor rebuild (month or so), but I WILL report back whenever I do and keep you guys updated on how how it went, if it fixed it, etc. Thanks again!

Hi, lately if i really ever "get on it" with the SS, I hear about 2 pops coming from the middle of underneath the truck. You can also sort of feel it. The motor and transmission are fine. I can't even feel the transmission shift it's in such great shape and it doesn't even sound remotely close to the motor. The truck has 215k miles, but has been VERY well taken care of. I could be wrong, but I'm believing that the noise I'm hearing is coming from the transfer case. I've noticed that if I just drive the truck, the noise never occurs, but it's like it's only when I really get on the throttle is where it occurs. If I drop the truck in first gear, I can get it to happen repeatedly, due to the high torquing at such a low gear. It's still a consecutive 2 pops. If I don't get on it a bit, it never happens. The truck rides as smooth as butter. I'm thinking that maybe the chain is loose and needs to be replaced or I need to buy a rebuild kit with the back half of the casing and bearings, etc. The main driveshaft has a little bit of play and I've noticed a bit of grease around where it enters the transfer case. I was curious if anyone has any idea for the ideal online store to purchase such a rebuild kit. Or maybe someone has experienced the same issue and knows I'm un-accurate at the source of my popping. Thanks in advance guys!

We had a family trusted mechanic just take a look and when we showed him the noise it was making he crawled under and within 5 seconds he knew it was the cat. Claims he's seen it plenty of times before.

Yeah, definitely couldn't have made a better deal from an even greater seller. Has done nothing but helped me tremendously since I have first called him about buying the truck. Since the cat swap, the engine light has went off, and the truck runs like a charm. Couldn't ask for a smoother running truck. Still can't believe it has the miles that it does. Has definitely been taken care of.

Here's videos of the tapping. And as soon as I can, I'll see the cat temps and post them. (excuse the guy in boxers. Haha) http://www.youtube.com/watch?v=E74MDOQSWwk http://www.youtube.com/watch?v=z9qb5EMgrrQ

I'm just worried about the ticking? What in the world could that be? Think my torque converter just had it and maybe a flywheel bolt snapped?

Sounds like it's coming from torque converter

No, does it while idling.

There's a small "tapping" noise underneath the truck? Any idea?

Yep, random misfire. People are telling me to lean towards the 02 sensor going out?

Hi, I was pulling off from my driveway and went to drive off from a still and heard two pops. After that, the truck would barely go. Seems like the more I push the peddle down, the more it bogs down and goes slower. Also, when idling, the truck vibrates pretty heavily. Check engine light is on. Any help is appreciated. I also just got it today, but I drove it 3 hours back perfectly fine. Guy even told me to "step on it" when I test drove it and it did fine. Sucked me to the seat and hauled ass. so I don't think it was "bandaged." and just sold to me. It was a "as is" bill of sale so as far as warranty, there isn't one. Any help is appreciated. Thanks.
