What do i hav to check so my car wnt throw white smoke?

The coolant level is good it doesnt move wen i turn on da car nd da oul is also clean.. i cheked everythin nd it uses to much gas.. im guessin its nt burning the gas because it the amike smells like gas and alot of fluid comes out the myffler which also smels like the gas dat its not burnin...

Does it have a Service Engine Soon/Check Engine Light on?

Yes it shows multiple misfires nd da code po1320.. we cleaned everythin nd double checked everythin nd its all good nd still throws all da white smoke

There is a TSB for code P1320. It says all 6 coils need to be changed. If the resistance is to low on the coils they will fire cold and not burn all the fuel. You can start there. Good luck.
