Hi. I recently changed the spark plugs in my 2003 camry v6, having to take off the intake manifold to get at the back 3 plugs, and now my check engine light is on. The code reads 'System too lean (bank 1)' so I'm assuming I have a small air leak. I didn't replace the gasket on the intake, should I have? I went to O'Reilly's to ask about it and couldn't get a straight answer. When they tried to look up the intake manifold gasket in their computer it shows that you have to buy a package of 4 gaskets but it seems that I should only need to replace one: the gasket between the intake manifold (plenum) and the head (? Or block. Whatever the manifold attaches to). Are there actually 4 gaskets that I need to replace? Do you think the gasket between the manifold and head is a likely place for an air leak? Thanks for any help you can give.
have the same problem?
