Most of the oil or additives are just that, you add them and supposed to fix things normally they do not. Scan for codes and check fuel pressure and get back with us.

Hello KSHITIJ,

If you decide to scan for codes and check the fuel pressure yourself, here are links to a couple of articles form this site that feature written step by step instructions and pictures explaining how to do the scan yourself, also I have included a link to our YouTube channel with a how to video on code scanning. In addition I have included a link to another article from this site explaining the process of checking the fuel pressure yourself. If you decide you would like do this yourself you can purchase a fuel pressure gauge online from sites like Amazon.com. Most scanners are fairly inexpensive to purchase. Once you have the codes please get back to us so that we can further assist you. We are always happy to help.
