Welcome to Justanswer, My name is Danny I am here to help.
Please let me know what is going on?
i have a 93 gmc serria pickup place the gasket manafold , sensor capteur , premium oxygen sensor and the idle is so high
very high idle. This is a prooblem with the idle air control valve
replace and clean the throttle body then it will idle normal again
Common problem on this modek
Let me know if you have any questions
what is a throttle body
let me get a image
31 is the IAC
what carberatour cleaner should i use?
use throttle body cleaner
Safe on the sensors
IS there any specific one in mind?
I always use whats on sale at the parts store
That will work perfectly
okay is it best if i spray it all inside while its running? or if its off?
off is fine running will not let it clean it out as good
okay one more thing should i take out the throttle sensor and spray inside too? or just the throtle body?
Yes and if this doesnt clear it up you will have to replace the IAC #31 in the pic
If this was helpful please take a moment to kindly press the green ACCEPT button in the lower right hand corner. Thanks in advance Danny
okay I already had replaced that part..
This and the throttle position sensor?
If cleaning it doesnt help and there are no leaks then I suspect there is something internal of the throttle body leaking down causing it to idle high
so then replacing the throttle body in general would be best?
Yes thats one way to do it or a overhaul
ok whats an overhaul?
It will completely be disassembled all new gaskets seals and cleaning is done. Anything broken is replaced
okay thanks alot!! you were a huge help!
