So yesterday I just replaced my starter and in the process, I think we didn't seat the inatake manifold gasket.

I've only driven about 40 miles so far, and was wondering do I have to buy a new gasket, or can I reuse it and reseat it properly again?

In case you're wondering, the check engine light told me this, with catalytic codes saying low efficiency, temp and bank 1.

You can test to be sure it is leaking before going there?

Not sure of the actual codes (0420 and the whatever the other two were) but I would recheck all of your work......did you seat all of the connectors?

Yea, we reseated all our connections.

Update we did:

We're thinking the check engine light came on because we had removed all the sensors when replacing the starter. So we're going drive it for 200 miles and see if the light goes off. If it doesn't my stepdad/mechanic will erase the code.

Sounds like you need a new cat......

Works!

After driving 90 miles, the light went out. Due to un-plugging and plugging, it just took some time for the computer to reset itself.
