Asslam o alikum sir ,
Need your professional assistance,
I had an issue with my 2007 corolla xli , in the earlier stage, when ever I turn the A/C ON , RPM droped down to less than 800 and engine shaked with A/C, without was fine , then I figured out it need Throtle Body cleaning , Because it was kind of cloged with carbon , then took a Throtle Body appart & gave it a good clean with petrol and carburator cleaner , Idle valve was a kind of stiff , after cleaning , engine is running smooth but the only problem is Higher Idle upto 12-1300 in normal condetion, but with the A/C it drops down to 1000 which is still higher ,
Waiting for your Kind reply,
Regards
Usman Ajmal
