after vacume line replacment car stalls?
 
The car was running ok before I replaced the vac lines. But I was getting no boost 5psi at max. The car idels fine but when you rev the engine it hesitates and bogs down and if I try to drive it stalls.

What did I do wrong? I tried searching but dont know where to start.

Checked all selonoids and pass valves and followed the diagram And felt very positive about the job.

My lower manafold dosent have a egr valve on it but I did have the selonoid so I capped it off. Could that be it?

It also has a clicking sound by the plenum that wasnt there before.

Thanks for any help Im sure you can tell that Im new

Have you started troubleshooting using Section F of the FSM yet? TPS or a problem with the MAP sensor would be first guess.

Wow 17 pounds per square inch @ 1000 rpms!!! What a torque curve huh?!!

Thanks Ill start there. The map sensor broke and I glued it. Not so good I guess

Not when you can get a used MAP for $40.

This might explain why it at least idles well, I'd say your pressure reading won't work well with it cracked and you should look for a used one in the parts for sale/wanted section for 3rd gens or call Ray Crowe up and get a new one, who knows you may have done the job correctly but won't know till it's fixed.
