Arrow What have i done now?

about a month ago i started smelling gas and through you guys determined it

was the pulsation damper. so i ordered the part and then installed it. as i was

putting the upper intake manifold back on i broke 3 or 4 of the vacuum lines and

the black and green one way something or other that was also connected to

some vac lines just under the trottle body. so i got some new hose and one of

those things. i replaced the ones i broke and some others. i finally got it all back

together and it ran great for about 15-20 seconds but then it died. i started it

again and it reved up to 3 grand like normal but then died. it does this now every

time i try to start it. did i maybe cross one of the vac lines or not put something

back on right? any help is much apreciated

Did you re-use intake manifold gaskets, or replace them?

Which vacuum connections did you break off? Emissions solenoids? What color plugs? The only one that really matters is the FPR, which has an orange plug.

Releif solonoid does matter (not that its the one you broke) just stating some do matter. Break off that nipple its attached to and have no hose. See what happens. I did, and the fugger would rarely start. Or it kept flooding. My experience with the vacuum system. MOST are there for a reason. Mine got fixed thanks to a member on here that got me the solonoid I needed.
Mine was the blue plug.

The relief solenoid has zip to do with the engine running. It is used by the ACV for emissions purposes. A small vacuum leak from a disconnected line would not be enough to affect idle much either. I've had rubber caps fall off unused manifold nipples, and idle never skipped a beat. You need a leak larger than that to make it stall.

Besides, the problem was already found, and it wasn't relief solenoid related.

NO NO NO, you read me wrong. one of the posters above me stated none of the solonoids do anything besides th FPR, I was stating, I beg to differ, from me experience with a broken nipple on my releif solonoid. It either flooded, really hard started, or not start at all, until I got a new one. Since then, starts everytime, it wasn't something else as I didnt replace anything else.
