So ive been having all kinds of problems with the swap i bought. Its 4 years old and the previous owner did nothing but beat on it I guess. It ran fine when the swap was done by a shop and the shop sold it to the guy I bought it from. When i picked it up it took forever to start and had a boost leak. Ive since fixed alot of problems but now have a idle issue. My fuel pressure was not right so I put in a aftermarket FPR with a guage so I could moitor it better. Now when the car comes to a stop at a light or something it just dies. Or when you rev the enine past 2k it just dies. Holds fuel pressure fine and my pump continues to prime so I dont think its fuel. Also just put in new spark plugs and cleaned the IVAC. Was idling around 2k before I did the FPR and plugs so I thought i did some good cause not its a pretty constant 900-1100 idle. When you hammer on the gas the thing takes off like a rocket and spools fine, it will continue to drive as long as you dont let it go back to idling range.

Is your BOV venting to atmosphere?

BOV is functioning like it should.

If you're venting to atmosphere and still using a MAF... that's most likely the cause of your problem.

Well i didnt have this problem before. So i thought it might be something i did? However lots of things are old on this swap.
