GM-GMC: starting issue, oriellys, high pitch

Question
I had Jiffy Lube do oil change,they pull PVC to inspect and forget to put back in valve cover.I hear high pitch noise,I open hood to inspect, see PVC hanging there, I put it in valve cover.Now it starts harder- meaning it turn over&over&over to start,before this oil change/inspection my truck was a turn key fire right up unit.SO WHAT HAPPENED TO CAUSE THIS?? & WHAT HAS TO BE DONE TO CORRECT THIS??  Thank you for your time,MARK

Answer
Unfortunately I do not know this would be something I would suggest taking to an auto parts store that offers free diagnostics. They can put a tech tool on your vehicle and see if it throws out any codes. Places like oriellys and autozone offer this. I am sorry I could not be of more help.

I would have gone back to that jiffy lube and told them or asked them why they did that.
