Hey guys

quick question, on cold start up. my Z when it turns over it'll fire up, with revs going to whatever they do, as the revs decline to idle, it'll stall. i can start it 2-3-4 times and it'll stall only once and a while. if i fire it up and give it a shot of gas it'll be fine..... any ideas?. i was going to start with a fuel filter and see how it goes, no codes no engine light.. dealer says spend 200 bucks on a tune up... no thanks
