runing rich and no power?

would a missing intake manifold bolt create a bad enough vacuum leak to make it run like ****. It is running pig rich its spewing out raw gas and if you rev it up over 3k it starts backfiring like hell once you let off. This is my first S5 NA I have messed with older stuff but nothing thats so relying on ECU.

spray some carb cleaner around intake where bolt is missing to see if it changes idle. I would have to say sealing intake properly would be a first step.

i got the bolt in there. still no real difference going to pull a map censor out of the garage and see if that might be a problem I know on my fd if you unplugged the dam thing it would go way into the rich. It also not pulling a whole lot of vaccum like 10-12 psi around 1kish idle.
