witz04 Posted December 5, 2003 Share Posted December 5, 2003 My '99 GS300 does not like to drive in a city going from traffic light to traffic light. While accelerating from standing still it accelerates relatively slow and it seems to make high RPM sounds as if it lacks power or is confused. This is the only time it accurs. Once in motion the car appears to be doing fine. Unfortunately resetting the ECU by unplugging the battery did not work. Does anybody recognize this? Thanks!

jdmparts_guru Posted December 5, 2003 Share Posted December 5, 2003 I have a '98 GS300 and do not have this issues (knock wood :P ) How long did you take of th power from the battery? You need probably more time, let's say a few minutes. But the way, I recently changed my existing airfilter for a new sports one and have a slightly better performance/reaction (also more noise ;) ) Quote Link to comment Share on other sites More sharing options...
SKperformance Posted December 5, 2003 Share Posted December 5, 2003 Is the transmission in snow mode? Quote Link to comment Share on other sites More sharing options...
jdmparts_guru Posted December 5, 2003 Share Posted December 5, 2003 I do not think it is the SNOW mode. This mode will only be active if you press it and will reset itself after each time. Quote Link to comment Share on other sites More sharing options...
witz04 Posted December 5, 2003 Author Share Posted December 5, 2003 Thanks for your suggestions! I replaced the battery last week so I assume this would allow enough time for the ECU to be resetted. The transmission is in regular mode, not in snow mode. The sluggishness shows up where there is a lot of stop and go and sometimes I have the feeling that the more I am in this mode at one time the worse it gets during that period.

pjobrien Posted December 5, 2003 Share Posted December 5, 2003 It might alos be that it takes some time for the poer to go from the front to the rear wheels. I have not had this problem, but others have said that it occurs in city because of allo the stop and go. the car has to keep transfrering power so it takes a liitle ttime to cathch up, also being that the car is relativley heavy and is rear wheel drive. the only other thing that I can think of is your transmission might be heating up and you might be in need of a transmission cooler.

jdmparts_guru Posted December 7, 2003 Share Posted December 7, 2003 Before I would do any hardware change, I would also replace the transmission oil and flush the autotransmission box. Quote Link to comment Share on other sites More sharing options...
witz04 Posted December 22, 2003 Author Share Posted December 22, 2003 All - THANKS for your advise. I followed the Guru's recommendation to change the transmission oil and have the system cleaned. No doubt the car drives better. Have not had the chance to city drive. Will update as soon as I do. Quote Link to comment Share on other sites More sharing options...
