many problems started

[90rslaser]

ok guys this is gonna be a long but please bare with me here.first, i took apart all my stock intercooler piping to clean it all out. i reinstalled everything the way it came out. now when i hit boost, my stock crushed BOV doesnt sound except for a little bit of a chadder(almost like compressor surge). what the hell would be causing this. 2nd problem. after all of that, my car idles fine when i drive normal and dont hit boost. but if i hit boost and then come to a stop, my car missfires at idle. it will does all night/day unless i turn the car off and let it sit for a few minutes then turn it back on. 3rd problem. when i DO hit boost my car has a little bit of hesitation, not boost lag i know what that is. but almost like i have drag on the car or something. only does this in first gear though. but every other gear it acts fine untill i hit higher rpm's(while under boost) and then it kinda stutters or something. please guys, help me resolve all these issues. it all started when i cleaned out the stock intercooler piping then replaced it. thanks

what condition is the intercooler outlet tube. They are notorious of corrosion and you may have a small pinhole in it causing a boost leak. Which leads me to ask, Is everything tight.

Do a boost leak test...

Check for codes and pull a datalog if you can and post it. I can think of a lot of things that will cause your car to do that. How's fuel pressure .....

how do i pull a data log? and wheres the best place to have check for codes? i dont have a scanner and the only places around here that i know of that can do our obd1 scanner program is midas. i dont know if vatozone or advanced autoparts or checkers has the obd1 scanner

Check your BOV, and the vacum hose to the BOV. It sounds like you may be experiencing compressor surge.

As for the missfire after boosting, check that your fuel pressure is ok, and that your vacum hose to the FP regulator isn't kinked. If boost pressure remains in the regulator, you'll have residual high fuel pressure after boosting.
