Drove the car to work today and it's running very well. When I got home I wanted to check a couple things. Don't know why I did it, but the last thing was to spray some carb cleaner around to check for vacuum leaks. When I sprayed some under the plenum, she almost stalled out. Sumbitch! I thought I'd found all the vacuum leaks.
Question is, what's under the plenum that might allow it to suck air? Could there be a crack? Great, gives me another excuse to wrench on the car. Also should allow me to lean it out a bit more at the AFM. It's L-jet, btw. Any ideas? |

Check the trough-tubes on the plenum. Almost all cracks i have seen where around those tubes and they can be somewhat hard to spot.
