First initial thought was vacuum leak, but specific cylinder misfires makes me think its injectors. MAF? Just checking anybody else's initial thoughts. Thanks guys!

Carbon build up

ericA6

I was hoping that wouldn't be mentioned... And it s the first reply!!! Crap!

AndreNY

does it get better within a minute of the car running?

ericA6

A few minutes... Yep

ericA6

Couldn't find any vacuum leaks. Can anyone else chime in with any ideas?

royclark

Pull the wire off the MAF and see if it makes any difference.

ericA6

Are you thinking a dirty MAF? Or what would that indicate?

royclark

It can't hurt to start with the things that cost nothing.
If your MAF is causing a weak mixture at start up, it will get better as the engine warms up, like pulling the choke out on older cars.
