This is a repost, I recently have developed a problem with my 99 es 300 with 93k miles. The car would stall out after starting for the first time of the day, I had to hold my foot on the gas for about 3 minutes before it would go. I was told to clean the throttle body, I sprayed throttle body cleaner in theTB as best I could without taking it off.

Now, after 3 days The car always feels like its going to stall and usually does after I start it. just got codes P0125 P1135 and P1133. Now I am nervious to drive to the toyota dealer 20 miles away, I know it will stall in traffic, Does anyone know what could be this cause? anyone have similar problem? , always get excelent advise from this forum thats why I check here before calling around. any help would be much appreciated.

 

check if you have a vacum leak... it'll sound like a ball giving off air.
clean intake filter?
clean TB?, did you take off the hose from the TB to the intake and clean the Trottle?

on idle, what kind of sounds does your car makes?
