Well i have been trying to get an 86 rx7 to run for a few days now. After putting in a new fuel pump, filter, spark plugs, changed all fluids. Well now it will start put will sputter and die. If i rev it when i get it started it will rev and stay running as long as i keep the rpms at like 2k. But if i let go of the gas it will sputter and die.
And i have tried to search but i havent found anything exactly like this. But from what i can see it might be a vacuum leak. If anyone has any ideas it would be greatly appreicaited.

 

vac. leak.
