i attempted putting in a SRI and found out im missing the damn mas adaptor plate and some other shi* and somehow i lost a bolt to my mas now my idle is below 1000. is it cause im missing a bolt? is this bad for my car?

 

I really couldn't tell you.. but find that bolt, your MAS might be reading incorrectly... But BTW I put a grounding kit and my idle is at just about 500... so I wouldn't worry about low idle.

It's bad for your car. You could be running lean or rich. ECU might be confused. Go the some hardware store and buy bolts!
