98 Lumina Code P0102

Replaced the thermostat today on my 98 Lumina 3.1 Went to start it and service engine lite came on and Wont stay running. Checked the scanner and Code P0102 comes up I know it has to do with the Map sensor. Has anyone else had do deal with this. Just trying to figure out what to look at in the morning Thanks Gary

look at your maf connections on the throttle body or the main vacuum connection on the TB.
