the car has the 2.2L correct? the coil packs are located near the bottom of the motor on the firewall side. I'm thinking that maybe you could have knocked a plugwire or 2 off the coil pack

your best bet would be to first get the codes scanned to see what is throwing the SES light. most likely you are going to have a misfire code. see what cylinder it is, then that will break down your problem
