:::closing the loop::: I crawled around banging on parts with a rubber mallet, and found one of the exhaust hangers was loose... After some contortionism I was able to tighten it... Voilà... Noise gone! It's hard to believe a bolt with only a couple of turns of play could make that racket! Thanks to everyone!
Thanks to all of my "online mechanics"!! It seems as if the consensus is an issue with either a loose heat shield (perhaps not tightened after coil pack install), or an problem with one of the cats. I will have it checked by my Indy asap. I needed front brake pads and an oil change anyway... If it is one of the cats, and they are no longer in warranty (no cel), then it might be time for cat bypass pipes?! :)
All engine gurus, I need help. While checking my parking spot today I heard the strangest sporadic metallic rattling from the passenger side of the engine. I could not really localize the sound (hoping it was from the cats maybe, and NOT the engine itself). It sounds ominous to me. The car just had 2 new coil packs and 6 new spark plugs installed, and is otherwise running GREAT. Here is the sound... you hear it right away (sounds like Im starting the car, but its just the weird sound), and then again at 9 seconds or so... http://www.aliota.com/js2k/engine-noise.mp3 Any help TRULY appreciated!
Just to close the door.... Changed all the plugs... and the 2 cracked coil packs... and voila! Running as smooth as ever!! A full test drive - and no thrown codes. :)
UPDATE:::: So despite the very generous offerings of some local guys, I ended up bringing the car to my indy (Motorwerks - awesome guys). Code said: random misfires. So we'll try changing the plugs and going from there... so much for "no apparent issue". :) The car almost has 50K miles and has not yet had the plugs changed (8 years)... hopefully this will be the solution!
judgejon, thanks man! She is running good. For a moment I was looking to trade her in for something a little more "hard-core", but I love her too much! I think the Durametric is a great idea - esp since I'd like to keep the car for a while. Here is some recent footage of the old girl in action... http://www.youtube.com/user/Iatrodesign JeTexas, thanks again for the input and for offering to help read the codes... you're an example of what a great community this is! Im going to clean the MAF when I do my oil change / x51 pan install ~ fingers crossed no more CEL!
... ok, this afternoon I started my car... and the CEL was gone! What gives?
Sent you a pm. I'd really appreciate the help. ~J.
Thanks for the replies. I will try to get a code reader to dive deeper. I hope its my cats so that I can upgrade! lol :)
All, Quick question for those much more knowledgeable than me... My 02 C4S has been running great, and just spent a weekend at Harris Hill Road performing like a champ! I drove the car home and to/from work the next 2 days with no apparent issue. Then yesterday I got a CEL after starting the car in the parking lot. I drove the car home, and it did not sound or behave any differently than usual. I thought perhaps I had not tightened the oil fill cap after topping off, but it was on securely... The on-board computer just says "drive to workshop" or something like that. Questions: is it safe to still drive the car minimally, and is there a way to get more specific information about the CEL? I already have a service apt with my Indy for Monday (soonest avail)... Thanks to all!
Malakas replied to Malakas's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Right on here! The previous tires (which had been in my garage >1 year) are much older (2 years) than the new one. So the new one is obviously softer... and hence pulling a bit to that side. Well, I guess I have my answer. Thanks!!

I have a 2002 C4S with nothing modified on the suspension. About 1 month ago, I hit some road debris and punctured my passenger front tire (2000 mile old Pirelli). The tire was patched until a new one was ordered. I then had my indy do an alignment (forgetting about the tire). The car drove perfectly. The next day I had the tire changed by my dealer and I noticed that the car was pulling to the right. The dealer said this could be because I had one new and one used (only 2000 mile used) tire on the front. Hmmmm.... So I had the alignment checked again by my indy. Still perfect. Now the car is pulling even worse to the right... Anyone recommend a way to diagnose the issue? I was thinking about just swapping wheels in the front and seeing if the car pulls to the opposite direction. I am hesitant to bring it back to the dealer because they will just swap suspension parts until the issue and about 1000 of my dollars goes away. Thanks to anyone who can help!!
Malakas replied to superporschefan's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I only have experience with ZAINO, but the results have always been incredible. In addition, they have terrific customer service - one of the owners even emailed me once on a Sunday afternoon.
Hey John, Sounds like our mileages are pretty close... I just did my 45K, but am too nervous to not extend my warranty. ;) I think Im coming up on a new clutch too - but local places are asking $2200... which seems steep. To stay on topic: my local service guy also inspected my aircon blowers for debris when I was there... I hear its pretty common to trap stuff, and/or foul up a fan. Just FYI. Best, J.
