viggenftw Is there any diagram for how the vacuum lines should be? Where is the bpc located? He checked turbo lines they were clamped properly... thanks for the support guys I can't wait to get her back haha

Turbo00 Platonoffs shifter alignment is a great walkthrough, just need a couple small allen keys to keep everything lined up. You don't realize how off your shift is until you go through the process.

As far as power, does it sputter at all? If he replaced the radiator chances are he had to unplug the BPC. Verify that the vac lines are all in the right place. Check the lines/clamps on the cast aluminum pipe that goes from the MAF to the intake side of the turbo. Basically, look at where all the parts are that he replaced, and if it looks like he had to move/take something off, look around for odd connections or unplugged vac lines.

viggenftw thanks john ill have him check that... its funny cuz i can hear the boostand when boost kicks in the car does pull a little more... anyways ill tell him to check... now what is the W hose?
09-27-2012 09:55 AM
JZW Sounds like boost leak, one of the ic clamps is not tight and all the boost just goes out past the clamp. Do a simple W hose test, pull the W hose, the middle hose on the BPC or boost pressure control valve and if it boost fine, then its the bpc or something, if it still does not boost, its most likely a boost leak somewhere,

viggenftw nice... thanks harvey... so does anyone have any idea why im not getting any power after all that work was done? i can floor it in first n the car just barely has the power to move... n it doesnt matter if i floor it, or use light throttle it's the same thing... anyone?

Harvey's Autohaus I discussed shifter alignment @ the end of this thread.

Slow Joe I haven't done this personally... Yet (I will be doing it this weekend though). I believe that You move the "lever" or shifter to align the hole in the front with another hole that is visible below. This will align the shifter.
09-26-2012 04:29 PM
viggenftw one question related to the linkage... in step 4 it says move the lever to align the hole in th elinkage rod... what lever? does it mean the shifter? what exactly am i trying to align the whole to?
09-26-2012 04:22 PM
viggenftw thank you for that link btw i shall try that
09-26-2012 04:20 PM
viggenftw no check engine light. the car just has like no power... so no idea what could be causing this? maybe a sensor in the wrong place or a screw put in the wrong place or a sensor hooked up wrong?

yea he's not someone who's worked on saabs before... he took good care of my buddys srt4 which is why i went to him in the first place but he cant seem to figure out whats going on here... anyone else?

bogan It's hard to find a good mechanic.

You need to properly re-align the shifter

Help with transmission swap please!!

Hey guys. Just took the viggen in for a transmission swap. Now, after the fact, the shifter isn't centered anymore. If anything, it's aligned with first gear? any idea on what could have happened and/or how i can fix it?

Also, i had the radiator replaced along with accessory belt, water pump, idler pulley, and tensioner. After everything was put in (trans and etc.) the car now has no power. It's barely putting along and it barely has any throttle response at all. Whether i floor it or not its the same. The mechanic has no idea why and i was wondering if there was anyone who has any idea what is going on.

Thanks for you help guys.
