Hey how are you ,I will Try to Help you with This Issue

If TB body cleaned and MAF sensor , we need to check for vacuum leaks and check fuel pressure ?

Do you a Capable scanner that can read fuel trims ,long term and short term and read the fuel status when engine warmed up, does it switch to Closed Loop Fuel Status from Open loop ?

oxygen sensor reading at idle and at operating temperature ?

what is maf reading at idle ?voltage and air flow ?

If you do not mind me asking are you looking for the most possible causes and taking it to a repair shop or you are repairing it yourself and you need step by step instructions
Please Let Me Know
Thank You
