Customer Question

I had a smog test on my 1995 Ford Aerostar 3.0 liter eng. The van failed the test because it was running to lean. What would be the cause of this condition?

Hello my name is ***** ***** I can assist you.
Expert:  CHRIS ZAPANTIS replied 6 months ago.
most of the time on those vans its due to a leaking intake manifold gasket.
Expert:  CHRIS ZAPANTIS replied 6 months ago.
Theres many reasons it can run lean but that is number one. Also the vacuum lines to pcv go bad.

The van just had the one the heads replaced because the van overheated and I know from experience that they have to remove the intake manifold Maybe they messed up when they put it all back together.

take a can of carburetor cleaner and spray it wherever you have vacuum if its leaking it will surge when you hit a leaky place.
