If engine light is on,go have it scanned,but IMO,it sound,s like the throttle position sensor may be bad,causing it not to idle under load.

Is that typically expensive and a lot of work?

Not really that bad,TPS is probably 70 dollar,s and labor 30 minutes,but that said go have it scanned to be sure this is the issue.
