I have a 1999 ES 300 w/240k, the CEL and the TRAC light or on I recently had the # 1 and 6 coil paks replaced. ran fine for a few months. but know the lights are on and every once in a while the car will sputter no acceleration... like its starving for gas... and the engine light will flash.... if I pull over shut the car off and wait 10 min. and start up it runs ok the lights are still on both but the CEL lights does not flash...I have not got any codes as of yet...appreciate any help on this... thank you...
