i just bouth my third rx7 but this one is a tII. the car starts fine everytime but wont stay running unless i keep my foot on the gas a little and when i shift the rpms drop and the car stalls. its not a big deal while im moving because i can pop the clutch but i want to fix this so i can just let it run. im thinking that the air is cutting out because i know its getting fuel. any thoughts as to what it could be?

 

Likely a vacuum leak. Check intake connections, vacuum lines, etc...
