As many of you know, I just topswapped a L26 into my 2002 GTP.
It cranks, however I am getting the indications of a vac leak. Boost gauge is jumping between 18-14 while it surges on idle.
The codes I get :
P0102 - MAF Code
P0445 - Evap Code
I found this thread about someone who had a similar issue. http://www.grandprixforums.net/p0443...nge-35815.html
However, I checked all fuses under the hood and all appears to be good. Maf was not removed, nor was TB and worked fine when removed.
So, correct me if I am wrong...the following things that could be allowing unmetered air ar as follows:
LIM Gasket
SC Gasket
TB Gasket
VAC Lines
Evap crap
I sprayed carb cleaner on my lines, and around the sc looking for an idle change, but couldnt find one. It's hard to listen for one when the car is surging.
For sh1t's and giggles I unplugged the MAF while it was surging...no change.
My plan at this point is to replace all the vac lines on top... since that will be the cheapest at this point... any ideas?
Should I delete the evap system for troubleshooting?
