I am sure someone has done some sort of write up on this but I need help as soon as possible. I got the 84 laser running, but now she wont idle. I checked all the vacuum lines and ran them the way they are supposed to be ran but now she does not idle at all. I will start it up and it will just die if I am not on the pedal just a little bit to keep the rpm up. also she stutters and backfires at low rpm until about 4000.
Have you checked the cam and ignition timing?
when I checked it during the build it was good. have not checked it since.
I would triple check the cam and ignition timing and go from there .
okay. I will see what i can do
would the timing jump just by hooking up the vac lines correctly
No, but having the vac lines hooked up incorrectly won't help the car to run right.
the timing was set when the car was running great, before the head gasket went bad. I will double check, but I think it is something else
sounds like cam timing off to me. Did you do it right with the coolant sensor unplugged and all that?
yes sir.
Thats ignition timing:thumb:Quote:

Pulled codes on her last night. got a 13, 22, 23, 31, 33, 34, 43, 55
13 means you don't have vac hooked up to the map properly or there is a leak somewhere in the line. Fix that first and then pull the rest.
Fixed all the codes. Drove the car around last night, at wot the car went into overboost shutdown and about made me eat dash. no codes ar present after driving the car back to my house without going wide open. anyone know what i could do to fix this
hook it up correctly, as in having some vac line going to the wastegate and to a reference, either through the solenoids, manual boost controller, or directly.
All vacuum lines and everything else is hooked up correctly. I have gone threw the vac lines 3 times now. The car threw the overboost code. then it went out. not when driving the vehicle at wot it does not throw any codes, just falls on its face and hard
Either vac is not reaching the WG can as Berry suggested, or the arm on the SV or WG can is seized shut.
Well I got it fixed. Thank you berry. I am sorry that i didnt think it was the vacuum, but evedently it was. I replaced all the line and now she runs. now the only problem that I am having is the car will stumble when i punch the gas
