tta300 Posted July 31, 2004 Share Posted July 31, 2004 After cleaning the throttle body and idle control valve, the idle is steady but stays at 1000 rmp, a lot faster than it should be. Did I mess up or miss something here? I used the same procedure as I did to my other cars with success. Has anyone done the same before? Please comment.

SKperformance Posted July 31, 2004 Share Posted July 31, 2004 the engine will learn the new air ratio and should slowly change it Quote Link to comment Share on other sites More sharing options...
tta300 Posted August 17, 2004 Author Share Posted August 17, 2004 It has been over two weeks since I cleaned the idle air control valve. The idle speed is back to normal, but I still have the abrupt clunky feeling and noise when shifting from P to D or between R and D. The tranny shifting quality while driving is fine. I wonder if the problem is still related to IACV. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted August 18, 2004 Share Posted August 18, 2004 no ,it is related to the higher rpms when cold and you shifting the tranny into gear before it is ready causing it to thud until warm Quote Link to comment Share on other sites More sharing options...
tta300 Posted August 18, 2004 Author Share Posted August 18, 2004 The tranny has never shifted like this since new; no matter the engine was cold or hot. It all happens after the intake cleaning exercise. I left the negative battary post unbolted last night. The shifting is much better now. Thanks for your advice.
