and check engine light came on.


There's a few possibilities:

One of the plugs was bad You didn't tighten them properly You knocked a vacuum line off somewhere One of your coil packs failed or you forgot to plug it back in

If you knew the error code, that would help.

Checked tha car this AM. One of the spark-plug-coil connectors was not seated securely. All is good now. Thanks again.
