99blkgs Posted September 8, 2007 Share Posted September 8, 2007 well my smart !Removed! today decided to clean my throttle body and so i did. i took the intake assembly apart then all the hoses then all the bolts holding the throttle body in place and i removed the throttle body. while i was removing it i guess i spilled some engine coolant on top of the sparg plug wire and the sparg plug itself. after i cleand all the gunk from the throttle body i put everything back together without knowing and the car was idling at 2000rpm which surprised me i thought it was going to run perfect. i took it apart again cleaned all the spark plugs but it runs rough now and the idle needle keeps moving up and down. does anyone have any ideas whay my stupid !Removed! did to this car????? any suggestions would greatly help. thankxxxx Quote Link to comment Share on other sites More sharing options...

JIBBBY Posted September 10, 2007 Share Posted September 10, 2007 Well as far as the throttle body goes, you can just remove the big plastic hose inlet and use carb cleaner to clean out your throttle body..No need to remove it.. I would look to make sure you re-assembled it back together correctly...Check all the sensor connections too...No air leaks or detached hoses.. Lastly I would run the car and spray just the open end of the throttle body with STP carb cleaner and see if that helps... The car will want to stall when you remove the snorkel tube so maintain the idle manually...Spray and it will stall, repeat...Open the butterfly and spray that too....You won't blow your engine... It sounds like you have a vacume leak or air leak...Check those tiny rubbber hoses... Quote Link to comment Share on other sites More sharing options...

JIBBBY Posted September 12, 2007 Share Posted September 12, 2007 This all happened just after you removed and then reinstalled the throttle body? None of these problems were occuring prior to the TB removal? Wow, I don't know what to tell you...If you reinstalled everything correctly then just maybe you fouled the TPS sensor...The throttle position sensor... That could cause the idle to do funny things... Do any check engine lights come on or anything? How does the car run after a while? Does the idle balance out after a while, or does it constantly run high? There is a warm up period where the ECU (engine computer unit) raises the Idle until the motor reaches a certain temperature... Quote Link to comment Share on other sites More sharing options...

CarbonGS Posted September 13, 2007 Share Posted September 13, 2007 sounds like to me there is either a vacuum leak or your mass air flow sensor may need cleaning. Quote Link to comment Share on other sites More sharing options...
JIBBBY Posted September 13, 2007 Share Posted September 13, 2007 Could be when you removed the TB you jacked up the TPS - throttle position sensor... A vacume leak would cause the idle to be low and maybe even stall the motor...Vacume leak or MAF problem maybe? I don't know what to tell you...
