Gebo Posted July 17, 2011 Share Posted July 17, 2011 My '01 IS300 sucks under acceleration. Cleaned MAP, Throttle body, changed plugs. Took my finger and twisted the accelerator cable to simulate a wipe open throttle. The butterfly valve only went about half way. This would explain the poor acceleration under full throttle. Now, how do I fix this? Quote Link to comment Share on other sites More sharing options...
DEATH_AWAITS_YOU Posted July 25, 2011 Share Posted July 25, 2011 My '01 IS300 sucks under acceleration. Cleaned MAP, Throttle body, changed plugs.

Now, how do I fix this? Throttle plate won't open all the way if the engine isn't running. Throttle cable pulls electric motor that does all the work. I think you're barking up the wrong tree. Can you get the engine to rev up with shifter in neutral or park? Is the idle smooth? Is MIL on? Quote Link to comment Share on other sites More sharing options...
