So my ltfts are still at 16.4 and im still gettin the vacuum code. Just went back around the engine and both gaskets with carb spray and there was no change in the engines rpm. Here are all the codes that showed on my aeroforce.
p0107
p0171
p0530
p1107
The 107 & 1107 may have been because i removed the map plug will the car was running to check if it was bad.
