#2996 of 3003 Re: '02 IS300 brake issue [ron_m] by cwis300 Sep 18, 2007 (9:16 pm)
Replying to: ron_m (Dec 17, 2005 8:24 pm) I hope you don't mind me emailing you. I have just purchased a IS300 Sportcross. I have a similar problem as you have posted on the popping sound when you change gear from forward to reverse. Were you able to resolve your problem on your IS300? I had my brakes checked out by Toyota dealership prior to my purchase and they didn't find any problem. I didn't notice the problem till I brought the car. The brakes on my IS300 does not make a popping sound all the time when I brake, it only does it when I change it from reverse to forward or if I am on the freeway on a grade downhill and I am braking every 5 seconds. Any response from you on how how you resolved the popping sound from when you brake would be appreciated.
#2997 of 3003 Drive By Wire Hesitation by mark_f Dec 15, 2007 (4:27 pm)
I would like to add the IS300 to the toyota vehicles with Drive By Wire hesitation problems.   This is total unacceptable for this vehicle. The only way to fix it has been to put a non DBW TB on the car. Unfortunately this eliminates the CC and TCS.   Here is an item that tries to correct Toyotas inability to give a reliable throttle system. http://www.jdm-option.com/eng/parts/06_12/direct.html   I would also like to add that i experience the brake noise with the reverse and first stopping. Also the transmission clunk happens.   With the Throttle response, clutch dampening device and throttle dampening devices in place, this car is totally disconnected. No wonder the magazines gave the BMW a better recommendation.   Is it time to start a petition to get a re-calibration of throttle tip in like the appliance style Camry owners complained?

Replying to: mark_f (Dec 15, 2007 4:27 pm) "Is it time to start a petition to get a re-calibration of throttle tip in. . ."   Yeah. Good luck with that.   You might want to look at the IS250/350 boards, since almost no one posts on the 300 board anymore. What I think you will learn is that the people who drive the IS don't (generally) have a clue what throttle tip-in is, let alone how it should feel. You sound like an enthusiast. You're in the minority, in case you haven't noticed.   I'm guessing you bought this thing used. Enjoy (as best you can)! Replies to this message: kc567567 (Dec 16, 2007 5:31 pm)

Replying to: cdnpinhead (Dec 16, 2007 4:52 pm) You might also think about having the engine checked out ..... i seem to recall a failed Oxygen sensor and/or dirty injectors etc caused me some grief on my 2001 .... spend an extra $100 the next time its in the shop .... make sure you use high test gasoline as well.   KC
#3000 of 3003 reply by mark_f Dec 17, 2007 (8:25 am)
I frequent the is300.net forums (my.is) and changing to a supra TB is really the only way to correct it.   It does not feel like injectors or o2 sensor, i have never had any Error codes and i only use 93 octane gasoline.   It is just a lousy programming of the DBW. If you look at the Bee*R Direct throttle system it clearly shows almost a half second tip in time.   Either way, it is pretty sad that toyota has calibrated the reaction to be of this nature. And i plan to fully log all channels and report back my findings. Possibly not here, since people do not care as much.
#3001 of 3003 New member, 1st question by the3dstickman Jan 23, 2008 (4:03 pm)
Greetings, list. I just found this list and am happy to be on board. I've just been warned by a coworker that since I'm a newbie, I should post pics of my ride. Well, please be patient, I don't have any. Had the '300 for a couple of years now and have not taken any. its going to rain here any hour now, so as soon as I get the chance, I'll post some. Looking forward to bouncing my questions to the forum.....so here goes!!   Anyone had any ECU mods done? If so, what was the final outcome, and where/how much did it cost?

I'm on my second Toyota (actually Scion) and I'm interested in buying used IS300.   First all, I know IS300s are RWD. In reality, how is the IS300 in snow conditions? Is it TERRIBLE or is so-so? I currently own a tC and what I have learned you have learned how to drive it. Still driving in snow in a tC is still "So-So." But its not made for winter. I have to rotate tires each winter month to keep traction or I'll slide through red lights even if I'm stopping mile away.   Thanks for your inputs
