It is true Aqash knows his stuff but for some time i have noticed he is getting very careless. First (couple months ago) he hammered the Compressor pulley trying to take it off (even though he had puller and brought it later) and thus caused permanent damage to pulley. It cant be used any more because the major imperfections caused by hammering would tear the belt. Kabli pulley costs 1500 btw
Now when he changed the sensor, he forgot to connect the cng pipe back to the air in-take. I was hearing weird sound at a specific rpm and when i opened the hood, i saw the cng pipe was hanging and engine was sucking in unfiltered air directly
