Thank you. I am getting codes p0301 and p0300. I already change the spark plus, wires and coil. I get a strong smell of gas under the hood and really hard start up. I am certain it is a bad fuel injector.

Danny here. Code P0300 is random/multiple misfire and P0301 is cylinder number one misfire. It is possible to have a leaking/faulty number one Injector problem if Plugs, wires, and coils changed.

After removing intake manifold I found the number one fuel injector is burnt and the gasket for the manifold has oil all over them.

Danny here. After time the gaskets are prone to leaking especially after 100,000 miles.

Would that cause the car to puff grey/blue smoke from the exhaust?

Danny here. Yes, It would. Oil getting sucked into the combustion process would be the grey/blue smoke out the exhaust.

Yea because whenever I start it, I would see a puff of smoke and I saw some oil when I looked inside of the chamber. How long you think it would it take for the car to get the remaining of the oil out?

Danny here. I am sure it would not take long! That was just oil being burned that was leaking caused by the gaskets. Be sure to install new intake gaskets upon reassembly and that all surfaces are prepped/cleaned to insure a good seal. I have attached a diagram showing the proper torque sequence for installation. These bolts are to be torqued to 105 inch/LBS.
