ok i just installed my slp runners and adjustable fuel pressure regalotor and now the car isnt idleing right and i getting a pop in the intake. I didnt touch the ingination system wile doing the swap so i dont think its timming and there a horrible vaccum leak somewhere. can a vaccume leak cause poping in the intake? also the AFPR was used so can it be clogged and causeing me to run lean? any help whould be nice

 

fix the vaccum leak at all costs

do you have a fuel preasure tester

 

well the vaccum is at 10 inchs when i can get it to idel soim guessing one of the manifold gaskets are not sealing. the fuel pressure is kinda low at 37.5 so im going to tear it back apart and reseal the manifold

 

did you hook the vaccum line for the brake booster back up? I always forget. If you put a holley regulator on I suggest to take it off they are junk. I put one on and less than a year it was leaking. Put a new diagphram in and in less than 2 weeks its leaking. POS

 

naw it was just the upper intake gasket. is the holley AFPR really that bad? i got the TPIS ones and it seems like it kicks ***
