dk99 Posted September 10, 2002 Share Posted September 10, 2002 I am new at this so bear with me. I bought my 1999 GS300 less than 3 years ago (65,000 miles) and had no problems untill now. Less than a month ago it started stalling at the low rpm, not every time (no consistency) and also some times (no consistency again) it hesitates at the highway speeds. It feels like something holds back the transmission and then releases it (sonick boom). Dealer can not find anything wrong with the car, no computer codes show up!! Dealer is blindly changing parts with no cure so far. Please help! I welcome any suggestions or guesses. I do not enjoy my car anymore!!! :( Quote Link to comment Share on other sites More sharing options...
Rodders Posted September 10, 2002 Share Posted September 10, 2002 You might want to try resetting your ECU - the easiest way is to remove the battery connections for an hour or so. Quote Link to comment Share on other sites More sharing options...

dk99 Posted September 16, 2002 Author Share Posted September 16, 2002 Update on stalling and hesitating: The dealer changed TPS but the problem did not go away. No warning lights coming up on display! Resetting ECU did not do any good. Lexus dealer decided to keep the car until they find out what is wrong with it. Meanwhile they gave me a loaner to drive. I will keep you informed on any new developments Quote Link to comment Share on other sites More sharing options...
lenierdw Posted February 16, 2003 Share Posted February 16, 2003 I had the same problem. I have 98 GS 300 and the dealer took out all six spark plugs and found corrosion on 2 of them. This caused the hesitation during morning idling. I never had problems driving at highway speeds. I hope this helps. Quote Link to comment Share on other sites More sharing options...
ps930 Posted June 21, 2004 Share Posted June 21, 2004 dk99 What did the dealer figure out as the problem Quote Link to comment Share on other sites More sharing options...
