spine911 Posted March 13, 2009 Share Posted March 13, 2009 My 06 GS300 would stutter around 5000rpms when i floor it when idling, it would stutter (pause) at this point for about 2-3secs, then climb up to redline; after i repeat the same procedure 2nd-3rd time, it would just go to redline without pausing, or stuttering....It would do this "cycle" everytime after initial Start. Any thoughts??? I recently brought my car for service due to CEL which was diagnosed to have a bad Gas Cap (replaced), and a leak in the evap system, i dont think this stuttering is related to an evap. leak though. Car runs smooth, no noticeable power loss/miss fire when driving, No CEL currently , Stuttering happens with either a cold or warm engine.

John Stanley Posted March 14, 2009 Share Posted March 14, 2009 I've never redlined mine. Come to think of it, I don't think it's ever seen 5000 RPM. I'll wait to see what others say before I try it. Stan Quote Link to comment Share on other sites More sharing options...
