2003 toyota camry 4cyl le eng code p0456
Some times white smoke In the morning even in summer

 

Check the gas tank filler neck area for rust preventing the cap from sealing, the result is a vacuum leak.

 

will this vacuum leak effect my trans its sticking in second on the freeway

and one more question im at 89000 miles when should i give it a tune up and what type of plugs are best

 

These is a emissions system vacuum leak. It should not effect trans performance.

Has the trans fluid every been changed?

NGK or Denso plugs should be fine.
