So i took off the whole intake system of my 86 N/A to clean the engine bay around there,
While taking the air flow meter i was taking the two screws at the lug then saw connctions so i put it back right away. So found the clip retainer and plug came right off.

Put everything back as it was, try to start the engine and it starts but then it dies
yes I recheck everything, Is my air meter screw? ,Can't find the problem. Please help

 

Check your vaccum lines. 95% of the time this is the reason for "start then dies" problem.

 

I already did and everything is fine.

 

Funny...I'm having the same issues... lol If it helps any... check out the Color Vac Diagram I made up. It's for the S5's.
