Whats up guys, my 91 3.1L V6 91 RS cant and will not hold an idle. When you go to start it up you gotta give it gas or else it will just crank and crank. Once it starts tho it runs really rough and if you let off on the gas it just stalls out. I just had a new fuel pump in it less than a month ago. So anything helps at this point. Thanks guys!!

 

Check the fuel filter, pressure, regulator and injectors. Remove the idle air valve assembly and make sure all the passages are clean. Make sure the EGR isn't stuck open. Then.....

 

Okay, i found this line and i have no idea where it goes. Its connected to the EVAP camister purge valve. Any ideas?

 

There are a couple of rubber lines that connect to hard lines that go back to the fuel tank. There is also a vac line that winds up under the plenum to the vacuum block on top of the throttle body.

 

The car is just turning over now, i havent had the time to mess with it. Thanks for the help guys!
