could also try a header and exhaust if your wanting to free up some power... Cool, thanks for your reply bro! headers are a tough install right? I've also heard though that an exhaust system won't really add too much power, but I'm not too sure. What do you think?

Thank you for your response! I will have to look into it, but do you know how much the price will be roughly for the SRT intake with the ECU? Nevermind, I found the price on their site; I was being lazy :P

I have an '03 gs300 sportdesign and I wanted to add some power to it, so I figured I would replace the spark plugs to something a little better, maybe add a cold air intake, and add an ECU. My question is, which spark plugs, cold air intake and ecu would you guys recommend, preferably those who have experience lol ;p . I have been hearing some good talk about the denso, as well as the torquemaster spark plugs, but I dunno which ones to get. Also, I was leaning toward a K&N air intake, but for the ECU I have no clue, but I know you have to be careful about which one you get. If you guys have any other advice, or some other recommendations for me, I would really appreciate it! Thanks in advance!

I was getting this sound too, after I found that my antifreeze level was really low I’ve added more and it went a way. Check the level of your antifreeze. Hmm, interesting. Thanks for the option, I never would have though of that, I will have to check it out and let you all know if it works!

Did you check for mice? :D Mice? That's the most ridiculous thing I've ever.... oh wait... LOL jk hahaha ;)

Sorry if you took offense to my response to sakataj about the mice, I meant nothing personal by it. I was just having a bad day.

i didnt notice u said ONLY when the car accelerates. then no its not them. but im not jokin or kidding.....mice/rats in our cabin air filters and intake manifolds/engine bays has been a problem. im 100% serious! especially if u live outside the city http://www.clublexus.com/forums/gs-second-...n-the-dash.html http://www.clublexus.com/forums/gs-second-...-me-2200-a.html http://www.clublexus.com/forums/gs-second-...-dirty-rat.html http://www.clublexus.com/forums/gs-second-...-hate-rats.html http://www.clublexus.com/forums/gs-second-...art-update.html http://www.clublexus.com/forums/gs-second-...e-very-low.html http://www.clublexus.com/forums/gs-second-...e-dealer-2.html so no. i wasnt jokin. Sorry for the rude response sakataj, I appreciate your effort taking the time to respond to my question. I almost wish it were a rat, seems like it would be easier to eliminate the noise than it seems to be for this lol.

BillyShaft you are right, I guess I was just having a bad day, it's not like me to give rude responses like that, especially when someone takes the time to respond to my need. However, I think you could ease up on me a little bit too b/c it makes you sound a little bit hypocritical "fighting fire with fire", so to speak. Nonetheless, point taken and I apologize for the negative response sakataj. Thanks for the eye-opener BillyShaft; I mean that sincerely.

sadly that is true it could be rats or mice. check the cabin air filter for ne signs of them LOL do you expect me to believe you are serious? You would have to be 100% retarded to think that mice are making noise only when the car begins accelerating... hahaha thanks though, I haven't laughed that hard since I was a little school boy....

Hey everyone, As mentioned I have a 2003 GS300 Sport Design, and here is what happens. Not every time, but most times, when I am stopped at a light or whatever, and I start to accelerate, during those first 2 seconds or so of acceleration, I hear what sounds like little pebbles bouncing around behind the dashboard. At first I thought I was running over some gravel or pebbles and they were bouncing around against the car, but subsequently it happened on a regular basis so I knew that couldn't be it. Anybody have any idea what could be causing this "bouncing pebbles" sound? I don't think it is a huge deal b/c the car runs great, but I am just curious as to what it may be. Thank you in advance!
