A check engine light (reads as code 172) just appeared for me.

I got this car one week ago and it had no cel until this morning, following several hours of troubleshooting a no start condition (could be I disconnected something in the process)

The battery was disconnected most of the last 24 hours, driven 3-4 miles since last reconnect, so maybe pcm is still learning?

Have just replaced plugs, wires, air filter, fuel filter, cleaned maf, flushed radiator

any advice is appreciated.
