Default P1518 + symptoms...

I've read a few threads here on P1518 code, but didn't find anything with my specific issue. Thought I'd see if anyone has an idea.

Symptoms
  • Somewhat rough idel, intermittently
  • MIsses occasionally on freeway
  • When there is a downshift (going slower) and do a miled accellerationm, seems to do multiple quiet backfires.

2004 Drive by wire Corvette motor; 4L60e

What's your thoughts?

by the way, no trouble light.

I just cleared the codes. Seems to idling OK at the moment.
