i've just put on a big bore throttle body on, and now my car idles at like 1500 rpm or has a spuratic idle that goes up and down. it won't sit in one spot. has anyone else had this problem? is my ecu reading to much air or something? please help me..anyone. thanks

disconnect your idle sensor, and screw down your idle to whatever you want (usually 750-1000rpm) then reconnect the idle sensor, switch off the engine, reset the ECU, turn on the engine after resetting ecu and let it idle for 10-15 minutes. switch it off again, then turn it on again and drive

 

usaully what happens though, is that when the car is cold it will idle fine. its just after i beat on the car or drive it for a while, then the car will idle high or iradic. like1500rpm

 

u might want to clean the TB and put a new gasket, make sure its the right gasket, cause i was running a gsr gasket on an ls TB and it was idleling high and going up and down put when i put the LS Gasket it when back to normal, gaskets mean ao this days, lol

 

speaking of gaskets my dog just chewed the folowing gaskets...intake manifold gasket, t body gasket, that little oil pick up gasket, chewed on my head gasket(teeth marks) , chewed up my vtec solenoid rubber gasket with the little filter, chewed my timing belt, pwr steering and alternator belts.. and ive been waiting on these parts for two weeks...
